In 2024, the veteran lithium battery enterprises will be eliminated

  According to the latest data of China Automotive Power Battery Industry Innovation Alliance, from January to December, 2023, a total of 52 power battery enterprises in China’s new energy vehicle market achieved vehicle loading facilities, 5 fewer than the same period of last year, and the elimination rate was close to 10%.However, in other words, we should know more about it. sodium foil:20 The law of development has brought new vitality to the whole industry and revitalized the market. https://www.canrud.com/products/detail/6a65d3b2d5084d24b10540fe9edae280

  

  On the other hand, the top ten power battery enterprises have loaded 375.3GWh, accounting for 96.8% of the total vehicle. Compared with 95% in 2022, 93.5% in 2021 and 91.8% in 2020, power battery companies have staged the drama that the stronger the stronger.

  

  Power battery companies ranked lower are struggling.

  

  Gateway Power, a lithium battery factory owned by Galaxy, is obviously one of them. From January to October, 2023, the loading capacity of Gateway Power was only 0.88GWh, ranking 13th. Now, the company has stopped production for two months.

  Jiewei Power was established in 2009 with a registered capital of 1.218 billion yuan. It is a 15-year veteran lithium battery enterprise. Once, it was full of lofty sentiments. It became the top 3 in the power battery industry in five years, ranked among the top 3 in the world in 10 years, applied for IPO of A shares in 2022, and strived for listing in 2023. After all, it was “but before he could conquer, he was dead”.

  

  Obviously, in the power battery industry, there are still many battery manufacturers that are not as good as Jiewei Power. They are also facing many problems, even life and death tests. How do you spend this winter?

  

  01

  

  Small battery factories are getting worse every year.

  

  The person in charge of the lithium battery manufacturer who suffered in 2023 will definitely miss 2022, especially the “small factory” of lithium batteries.

  

  Wu Sujun, a grassroots employee who has worked in Jiewei Power for more than ten years, once told the media that the company still has some orders in 2022, but the quantity is not large. Mainly small modules, not finished products. In 2023, there was no order, and the factory could only do some battery repair work, and about 200 sets were repaired every month.

  

  Compared with more than 2,400 employees in the glorious period, gateway power had only about 400 employees left in its headquarters before the production stopped, and 200 people left after the production stopped. The 2022 annual report shows that in 2022, the number of social security participants of Jiewei Power was 882, which dropped by more than 70% in less than one year.

  

  The closed production lines record the cruelty of the lithium battery industry. According to the Shenzhen Communique of the 10th G20!-Lithium Battery Summit, since 2023, the average capacity utilization rate of domestic power batteries is less than 60%, and that of energy storage batteries is less than 55%.

  In fact, in addition to the power battery companies such as Jiewei Power, there are also four major materials (cathode materials, anode materials, separators and electrolytes) for lithium batteries.

  

  In terms of capacity utilization rate, many companies disclosed that the overall capacity utilization rate of the anode industry decreased significantly in 2023. Even the leading enterprise Shangtai Technology announced the suspension of production in the first quarter of 2023.

  

  On the evening of March 27, 2023, Shangtai Technology announced that Licheng Road Base had stopped production. It is reported that Licheng Road Base started construction in 2008. It is the earliest production base of Shangtai Technology, and also the starting place and birthplace of the company’s entrepreneurship, with an annual production capacity of over 10,000 tons.

  

  ”The supply and demand of the entire anode material industry has reversed, facing a situation of overcapacity.” Shangtai Technology clearly stated in the announcement.

  

  The performance of Ferrous lithium phosphate cathode manufacturers in operating rate is also relatively sluggish. According to market data, in November 2023, the average operating rate of manufacturers was less than 50%, and it has accelerated to about 20% since December. The output of cathode materials in Ferrous lithium phosphate has reached a new low since June 2023.

  Solve overcapacity

  

  ”Surplus” became the label of lithium battery industry in 2023.

  

  Mr. Gang ‘an, the technology developer of Jiewei Power, said that the company kept investing in building factories, which eventually led to overcapacity.

  

  How many lithium batteries did Gateway Power produce? According to the information of official website, Jiewei Power has two production bases, Yancheng and Changxing, with an effective production capacity of 10GWh. Jiewei Power CEO Lu Chenli announced in 2022 that the company plans to reach the power battery production capacity of 100GWh in 2025.

  

  Source/Gateway Power Official Website New Energy Prospective Screenshot

  

  Zhu Huarong, Chairman of Changan Automobile, once predicted that by 2025, the demand for power batteries in China will be 1000GWh, while the production capacity of the industry has reached 4800GWh, and the degree of excess can be imagined.

  

  The four major materials of lithium battery also have different degrees of surplus. Some organizations predict that the global electrolyte capacity planning will exceed the demand by 3.4 million tons in 2025.

  

  It is also a means of self-help for the lithium battery factory and the four major material enterprises behind it to delay the production capacity and adopt the low inventory procurement policy.

  

  The semi-annual report of Contemporary Amperex Technology Co., Limited in 2023 shows that its inventory is only 48.91 billion yuan, which is 27.76 billion yuan less than that at the end of 2022. Zhongchuang Singapore Airlines, the third in the industry, cleared its inventory slightly, and its inventory decreased from 11.82 billion yuan at the end of 2022 to 10 billion yuan, a decrease of 18.2%.

  

  Enterprises in the upper and middle reaches of lithium batteries have been kidnapped by the “game theory” of production capacity, forcing low inventory.

  

  Jin Yiteng, an open source securities company, said that as the pace of production scheduling in downstream battery factories declined and the price of lithium battery materials in the middle reaches continued to fall due to overcapacity, battery factories also adopted a lower raw material inventory procurement strategy, forcing middle-stream lithium battery materials enterprises to reduce their start-up, maintain low inventory, and delay the launch of new capacity.

  

  Low inventory is obtained on the premise of price reduction. According to the data of Xinyi Lithium Battery, an industry research institution, on January 24th, 2024, the average price of square Ferrous lithium phosphate power battery and energy storage battery was 0.38 yuan /Wh and 0.43 yuan /Wh, respectively, which was more than 50% lower than the price of 0.9 yuan /Wh in early 2023, and the price has reached the lowest point in history.

  

  The seriousness of the price reduction can be seen. According to the statistics of Hi-Tech Lithium Battery, compared with 2022, the gross profit margin of diaphragm listed companies in the third quarter of 2023 decreased by about 40%, the electrolyte field decreased by about 25%, the cathode field decreased by about 20%, the ternary cathode decreased by about 9%, and the iron-lithium cathode decreased by about 5%.

  

  03

  

  Power Battery 2024: More Fierce Fight

  

  ”After experiencing rapid growth in demand and production capacity, the lithium battery field is currently facing the challenge of overcapacity. It is expected that supply and demand will further deteriorate in 2024 and it is expected to ease in 2025. ” Huatai Securities pointed out.

  

I finally understand-thread locking is actually to prevent bolts from breaking.

  Bolt looseness is common, but if you don’t pay attention, it will often cause equipment vibration, component damage, and even casualties. How to tighten a small nut has always been a long-lasting topic in mechanical design. Today, let’s talk about the most basic method of fixing nuts in work.So, I believe left thread rock bolt In the future, it will be promising to create a miracle belonging to the industry. https://www.chinatianlong.com/

  

  In general, we analyze the bolt fracture from the following four aspects:

  

  First, the quality of bolts

  

  Second, the pre-tightening torque of bolts

  

  Third, the strength of bolts

  

  Fourthly, the fatigue strength of bolts.

  

  In fact, most cases of bolt fracture are caused by looseness, specifically, it is damaged due to looseness. Because the situation of bolt loosening and breaking is basically the same as that of fatigue fracture, finally, we can always find the reason from the fatigue strength. In fact, the fatigue strength is so great that we can’t imagine it, and the fatigue strength is not used at all in the use of bolts.

  

  01

  

  The bolt fracture is not due to the tensile strength of the bolt.

  

  Take a M20〜80 8.8-grade high-strength bolt as an example. Its weight is only 0.2kg, and its minimum tensile load is 20t, which is as high as 100,000 times its own weight. Under normal circumstances, we only use it to fasten 20kg parts, and only use one thousandth of its maximum capacity. Even under the action of other forces in the equipment, it is impossible to exceed 1,000 times the weight of the parts, so the tensile strength of threaded fasteners is sufficient and it is impossible to damage them because of insufficient strength of bolts.

  

  02

  

  The fracture of bolts is not due to the fatigue strength of bolts.

  

  Threaded fasteners can be loosened only 100 times in the transverse vibration loosening experiment, but they need to be vibrated repeatedly for one million times in the fatigue strength experiment. In other words, the threaded fastener is loose when using one ten thousandth of its fatigue strength, and we only use one ten thousandth of its great capacity, so the loosening of the threaded fastener is not due to the fatigue strength of the bolt.

  

  03

  

  The real reason for the damage of threaded fasteners is looseness.

  

  When the threaded fastener is loosened, it generates huge kinetic energy mv2, which directly acts on the fastener and equipment, causing the fastener to be damaged. After the fastener is damaged, the equipment cannot work in a normal state, further causing the equipment to be damaged.

  

  When the fastener is subjected to axial force, the thread is damaged and the bolt is pulled off.

  

  When the fastener is subjected to radial force, the bolt is cut and the bolt hole is oval.

  

  04

  

  Choosing thread locking mode with excellent locking effect is the fundamental solution to the problem.

  

  Take hydraulic hammer as an example. The weight of GT80 hydraulic hammer is 1.663 tons, and its side bolts are 7 sets of M42 bolts of grade 10.9. The tensile force of each bolt is 110 tons, and the pre-tightening force is half of the tensile force, and the pre-tightening force is as high as 300 to 400 tons. However, the bolt will break, and now it is ready to be changed to M48 bolt. The fundamental reason is that the bolt locking cannot be solved.

  

  When a bolt breaks, it is easy for people to conclude that the strength is not enough, so most of them adopt the method of increasing the strength grade of the bolt diameter. This method can increase the pre-tightening force of the bolt, and its friction force is also increased. Of course, the anti-loosening effect can also be improved, but this method is actually a non-professional method, and its investment is too large and its income is too small.

  

  In short, the bolt is: “If you don’t loosen it, it will break.”

  

  Cause analysis of bolt looseness

  

  The threaded connection is designed according to the self-locking condition: ψ +ρv, and the friction pair generated in the threaded pair makes the bolt self-lock to tighten the bolt, so the connection will not loosen automatically under static load. However, under impact, vibration, variable load and great temperature change, the friction force f of the screw pair will decrease or disappear instantly. If this phenomenon occurs repeatedly, the connecting bolt will gradually loosen. After the threaded fastener is loosened, the kinetic energy mv2 is generated, and the fastener subjected to axial force, the thread is destroyed and the bolt is pulled off. Fasteners subjected to radial force, bolts are cut and bolt holes are broken.

  

  Bolt locking principle: limit the relative motion between screw pairs or increase the difficulty of relative motion.

  

  Introduction of common anti-loosening methods

  

  There are three commonly used methods for locking bolts: friction locking, mechanical locking and permanent locking. Among them, mechanical locking and friction locking are called detachable locking, while permanent locking is called non-detachable locking.

  

  01

  

  Friction locking

  

  1. Spring gasket locking

  

  The anti-loosening principle of the spring washer is that after the spring washer is flattened, the spring washer will generate a continuous elastic force, so that the threaded connection pair between the nut and the bolt will maintain a friction force continuously and generate a resistance moment, thus preventing the nut from loosening. At the same time, the sharp corner at the opening of the spring washer is embedded into the surface of the bolt and the connected piece respectively, thus preventing the bolt from rotating relative to the connected piece.

  

  2. Lock the top nut (double nut)

  

  3. Self-locking nut locking

  

  One end of the nut is made into a non-circular convergent or radially convergent after being slit. When the nut is tightened, the closure expands, and the screwing threads are pressed by the elastic force of the closure.

  

  4. Locking of elastic ring nut

  

  Fiber or nylon is embedded in the thread to increase friction. The elastic ring also plays a role in preventing liquid leakage.

  

  02

  

  Mechanical locking

  

  Locking of groove nut and cotter pin

  

  2. Stop gasket

  

  After the nut is tightened, the single-ear or double-ear stop washer is bent and attached to the side of the nut and the connected part respectively to realize locking.

  

  3. Locking of series steel wire

  

  Use low-carbon steel wire to penetrate the holes in the head of each screw, and connect the screws in series to brake each other.

  

  03

  

  Permanent locking

  

  Commonly used permanent locking are: spot welding, riveting, bonding, etc. This method mostly destroys threaded fasteners during disassembly and cannot be reused.

  

  In addition, there are other ways to prevent loosening, such as: coating liquid adhesive between screwing threads, embedding nylon rings at the end of nuts, riveting and locking. Mechanical locking and friction locking are called detachable locking, while permanent locking is called non-detachable locking.

  

  1, punching method to prevent loose

  

  After the nut is tightened, the thread is damaged at the end of the thread.

  

  2. Adhesive Locking-Nut Locking Solution

  

  Apply the nut locking liquid to the bolt tightening position, and then screw on the nut. After self-curing, the locking effect is good.

How can you not know such knowledge of drawing cards

  In the chess game, listening to cards is a skill, and listening to cards is a craft. Listening to cards means that you are about to enter the stage of Hu cards, which means that the final victory will not be too far away. Generally, players on the field basically start to listen to cards at the later stage of the game. At this time, whoever listens well and can master the skills of listening to cards will win the game earlier. Today, the new recruitment game will come to say for everyone?Only by working together can we turn BL777 Casino The value of the play out, the development of the supply market needs. https://www.bl77777.com/

  

  1. Listen to multiple cards-in a card type, players usually choose to listen to several cards. For example, 2,345,000, and the cards drawn at this time are 20,000 and 50,000. If it’s 2,345,600, then the draw cards are 10,000, 40,000 and 70,000. However, players need to pay attention to the fact that if some of the cards in Hu are likely to destroy the overall card type, such as one-stop, flat Hu and so on.

  

  2. Listening is monotonous-it means that when players listen to cards, they just listen to a single card and want to make a pair.

  

  3. Listen to the hole-for a simple example, if the cards in the player’s hand are 20,000 or 40,000, then the card type that the player listens to at this time is 30,000 holes.

  

  4. Listen to the side card-listening to the side card is similar to listening to the hole. For example, at this time, the cards in the player’s hand are 70,000 and 80,000, so the card type that the player listens to at this time is 90,000.

  

  5. Listen right-if there are two pairs in the player’s hand, at this time, you only need to make another set of engravings, and the other set will be used as a card. In this case, the player needs to listen to two cards, and this card drawing type is called listening right.

  

  When listening to cards, players must pay attention to the card type of their family, and try not to listen to the same card type as their family, so as not to be called Hu by their family in advance. If your last family happens to be the dealer of the game in this bureau, it’s like avoiding listening to the same cards as your last family. If you can hide, you can hide!

Secrets that have to be told in chess games

  The so-called chess game is the floorboard of chess game and card game. Chess and card games have flourished since the Ming and Qing Dynasties. Mainly includes poker, landlords, China chess, military chess, gobang, mahjong and so on.Even if there are obstacles to moving forward, Jilibet We should also persevere, forge ahead bravely, cut waves in the sea of the market, hang on to Yun Fan and strive for the first place. https://www.bl77777.com/

  

  Chess and card games can be divided into poker, landlord fighting, mahjong, China chess, Go and military chess. It can be said that the richness of chess and card games is completely beyond your imagination.

  

  In China, Landlord Fighting, Mahjong and China Chess can be said to be the most well-known players. After all, China Chess can be said to be the quintessence of China, and Landlord Fighting Mahjong has become omniscient among the people. People over three years old basically know these chess games, so today we will talk about the unknown contents of these chess games.

  

  Dou dizhu, a popular Chinese poker; fighting the landlord

  

  Nowadays, most of the landlord fighting industries rely on online. Since the first full game of JJ Landlord Fighting was held online, the offline card game has not been adopted, and now online landlords are in full bloom. Online landlords have occupied half of the landlord fighting world, while offline landlords have struggled to survive in the residual wind of online landlords.
