CR2032 button cell battery

Analysis of the technical route competition of power CR2032 button cell battery

"I think the current power battery market is in an unhealthy competitive environment. The update speed of new battery technology and development routes has even exceeded the current car design. Perhaps in the next few years, CR2032 button cell battery may change completely." On November 26, Andreas Schabacker, technical director of German Electric Vehicle Research and Development Co., Ltd., said at the "Second China-Germany Automotive Conference". For the automotive industry of China and Germany, this year is undoubtedly a key development node. Especially in July, at the fifth China-Germany intergovernmental consultation meeting held in Berlin, China and Germany signed 22 agreements and letters of intent involving cooperation in the fields of science and technology and dataization. At the same time, representatives of enterprises from the two countries also signed a number of economic cooperation agreements with a total amount of US$30 billion. Among these cooperations, the automotive industry occupies almost half of the country. These include the announcement that the CATL battery factory will be located in Thuringia, Germany; JAC Motors and SEAT signed a memorandum of understanding; Great Wall Motors and BMW jointly established Beam Automotive... A closer look shows that most of the cooperation between the two parties involves the field of electric vehicles. It is precisely because one party has a huge consumer market and the other party has a century-old car manufacturing process that the cooperation between the two parties will be more conducive to becoming a weathervane for the development of the automobile industry. Therefore, the technical route of power CR2032 button cell battery has also become the most critical issue for Sino-German automobiles. At present, power CR2032 button cell battery show a trend of common development of multiple technical routes, mainly focusing on four battery materials: lithium iron phosphate, ternary materials, lithium cobalt oxide, and lithium manganese oxide. They are flourishing in their respective application fields and occupy a certain market share. Among them, lithium iron phosphate has good safety, long cycle life, abundant raw material resources, and less environmental pollution. But the disadvantages are also obvious. In addition to the extremely poor cycle performance at low temperatures, the main defects are its low conductivity and tap density, and its energy density is only 120-150wh/kg; lithium cobalt oxide is the earliest commercialized lithium battery positive electrode material, and its disadvantage is low mass specific capacity; the production process of lithium manganese oxide CR2032 button cell battery is very mature, and it is easier to carry the 18650 type CR2032 button cell battery used in Japan and South Korea. But lithium manganese oxide has poor high-temperature cycle performance; the main ternary materials are nickel cobalt aluminum oxide (NCA) and nickel cobalt manganese oxide (NCM), of which NCA is the material with the highest specific capacity among the current commercial positive electrode materials.

● How to choose the technical route? "Although many OEMs produce battery cells, they do not really control the battery cell technology. Because the investment risk is very huge. This also leads to that once the technical route of the new energy industry changes, a large amount of investment in the early stage will cause very large risks." said Xu Huanping, vice president of Mahle Technology Investment (China) Co., Ltd. Zhu Chaohong, director of the electric drive division of ZF Friedrichshafen AG, said frankly: "Among the three-electric systems, ZF is the only one that has not entered the battery field." The reason is battery technology and funding issues. He believes that CR2032 button cell battery occupy an important position in the entire electric drive. In order to achieve cost reduction, in addition to the basics, it is also necessary to consider what type of vehicle is used. To this end, Xu Huanping suggested that it would be best to achieve a relatively unified battery technology route as soon as possible, which would be conducive to the development of power battery companies. "The entire industry chain needs to consider this issue. Technology needs a life cycle, and it is developed under this life cycle linkage." So, how to choose the battery technology route? Zhang Jianfeng, director of new energy at Zhejiang Geely Research Institute, believes that the battery technology route ultimately needs to be combined with vehicle companies, battery companies, and upstream and downstream supporting companies to formulate a reasonable power battery development route. "This requires vehicle manufacturers to work closely with battery suppliers in order to enable our battery industry to develop rapidly." Therefore, in this system engineering, the advantage of vehicle manufacturers is that they are conducive to understanding the needs of the entire vehicle. They can propose some of the most basic restrictions on CR2032 button cell battery based on the vehicle's cruising range, such as energy density, power, and some basic requirements for thermal management. Battery suppliers can make some detailed designs based on these simple requirements, and analyze the feasibility from the perspectives of cost, safety, reliability, etc., so as to develop a reasonable battery route.

● Cost must be achieved first "Whether electric vehicles can be accepted by the market in the end depends on two aspects, one is cost, and the other is the same convenience as fuel vehicles. The power battery is undoubtedly the most important influencing factor." Xu Huanping said. Based on this, no matter which technical route is developed, how to achieve rapid cost reduction must be considered. In this regard, Zhang Jianfeng analyzed from four points: From the perspective of materials, the cost of battery cells can be reduced. Because the price of cobalt in ternary materials is relatively high, the cobalt content can be reduced by using different types of CR2032 button cell battery, which can be regarded as a way to reduce costs; from the perspective of battery modules, it is recommended to use a large number of large-capacity battery cells, which can introduce the cost of auxiliary shell materials; from the perspective of battery pack design, it is hoped that the design of the battery pack and the design of the entire vehicle should be integrated. In addition, costs can also be reduced through battery recycling. If we analyze the number of power battery products, lithium iron phosphate CR2032 button cell battery and ternary CR2032 button cell battery are used more frequently. In terms of future market development prospects, fuel cells and solid-state CR2032 button cell battery will eventually occupy a certain market position with the overall advancement of technology and the improvement of related supporting facilities, but in the short term, they are not enough to affect the market position of ternary and lithium iron phosphate. Therefore, we need to look at each technical route rationally, have sufficient foresight and market sensitivity, and then make reasonable market predictions.
