Analyze the development trend of lithium-ion battery packs

With the increasing application of lithium-ion battery packs in various fields, especially the gradual promotion in electric vehicles, new energy, military and other fields, countries and major companies have increased their research and development efforts. Material technology is constantly improving, and the research and development of lithium-ion batteries is accelerating integration. In 2018, a number of new technologies and new products appeared in the lithium-ion battery pouch industry. Lithium-ion battery packs first entered the consumer electronics market such as mobile phones, digital cameras, and notebook computers. It took several years to quickly occupy the world market, while nickel-cadmium batteries and nickel-hydrogen batteries quickly went out of the market. New energy vehicles have also greatly promoted the sales of lithium-ion battery packs. The development trend of lithium-ion battery packs: ▲Three parties comprehensively reduce costs: improve processes, reduce material costs, expand scale effects, increase output, and reduce production costs. Others: cascade utilization and modular design to reduce life cycle costs. ▲Double ways to increase specific energy: Physical methods: use large-capacity batteries to improve grouping efficiency. Chemical methods: use high nickel cathode materials and silicon-carbon cathode materials. At present, the basic system of lithium-ion batteries is relatively mature, and several mainstream ternary routes have been determined: iron phosphate Lithium, lithium manganate and lithium titanate. Due to its superior safety performance, lithium iron phosphate has been widely used in passenger cars in recent years. Compared with domestic manufacturers, lithium-ion battery packs have great advantages in terms of battery consistency, stability, safety, environmental protection, and cycle life, and are also very attractive to downstream manufacturers. The business model of cascade utilization, modular design, and vertical integration of the existing power lithium-ion battery industry is still greatly optimized. For example, the battery boom is about to retire, and the rational arrangement and use of retirement batteries will greatly improve the economic benefits of batteries, such as various automobile companies. Promoting modular design is to achieve economies of scale under the premise of batteries. For example, the closed-loop form of the company's upstream and downstream business is similar to BYD. These measures can further reduce battery costs. Disclaimer: Some pictures and content of articles published on this site are from the Internet.
