With the development of electronic products and new energy vehicles, consumers’ demand for power and energy storage is increasing. Lithium batteries have gradually replaced lead-acid batteries and have become the core components of new energy vehicles.  They are widely used in electronics, new energy vehicles and storage energy field. In addition, the government's requirements for energy conservation and environmental protection have increased, and relevant favorable policies have been introduced one after another, and the space for lithium batteries is expected to be further expanded. According to the Starting Point Research Institute (SPIR), the installed capacity in 2020 will reach more than 60GWH, which is the same as last year.  By 2025, the installed capacity of China's automobile power lithium battery will reach 232GWH, an increase of more than three times compared to 2020.

 

Power lithium battery refers to the lithium battery used in the power drive system, such as power tool lithium battery, geological prospecting, environmental monitoring, car model, airplane model, UAV lithium battery, balancing vehicle lithium battery, etc. Compared with ordinary consumer lithium batteries, power lithium batteries generally have more special requirements, high energy density, wide temperature range, support high-rate discharge, longer cycle life, and safer. The advantages of high energy density and long life of power lithium-ion battery make it become the most practical and valuable new energy electric vehicle battery candidate.  


In the next few years, as traditional fuel vehicle companies increase their deployment in the field of new energy vehicles, domestic and foreign power lithium battery market demand will maintain a rapid growth trend. Mainstream power lithium battery companies at home and abroad have announced substantial expansions in order to increase the company's production and sales scale, expand the scale effect, and reduce the production cost of unit products in response to the rapid development of the new energy industry.  


From the perspective of technological development, vehicle power battery technology is a bottleneck technology that restricts the industrialization of electric vehicles. With the gradual deepening of the industrialization of electric vehicles, countries and key enterprises have stepped up efforts to develop the power battery industry. The high specific energy power battery technology based on new materials and structures has become the focus of competition in various countries, greatly improving the safety of current vehicle power batteries , Life, low temperature characteristics, and cost reduction are the direction of industrial technology development.


While pure electric vehicles and plug-in mixed vehicles have achieved rapid development at domestic and foreign, mixed power vehicles, especially mixed vehicles and other energy-saving vehicles have also developed rapidly internationally. Light mixed vehicles require batteries to provide higher energy and even power. As a result, the 48V power system for vehicles is accelerating the development and application, and it is another extended application field and development opportunity where lithium-ion batteries may show advantages.
