Powerful driving for electric vehicles | Lithium battery pack output tripled in 6 years

Among many existing technologies, lithium-ion batteries have become the technology of choice for many applications. By 2022, the market value of rechargeable lithium-ion batteries will reach 59.1 billion US dollars. Consumer electronics as the main application market for traditional lithium-ion batteries. , has been replaced by electric vehicles, the application will account for 72% of the rechargeable lithium battery market in 2022. According to analysis by the market research agency Yole Développement (Yole), global battery demand will grow by more than 400% from 2016 to 2022; In order to meet such huge demand, more large-scale manufacturing plants must be built in the next few years.

At the same time, the battery pack market is also very attractive. Yole pointed out in its "Lithium Ion Battery Pack Report for Automotive and Fixed Storage Applications" that the annual output value of the lithium battery pack market will reach $87.3 billion by 2017. The compound annual growth rate is 27.6% between 20 and 20 years. The battery pack is a key component of large battery systems, such as BEV/PHEV, electric buses and trucks, and all-electric systems such as fixed battery energy storage systems. The second part is represented by the Battery Management System (BMS).

Battery pack manufacturers can increase the added value of differentiated battery pack designs, as well as BMS, thermal management solutions, safety equipment, electrical interconnects, enclosures and assemblies. Currently, many R&D efforts are concentrated. In the development of new lithium-ion battery materials (electrodes, electrolytes, separators, etc.) and future alternatives to lithium-ion battery technology, it has driven a large number of patent activities. In 2017, more than 30,400 new patents were issued, and patents were granted. 30,900 pieces, and more than 6,400 patents have expired.
