Prohibition on the production of liquid-cooled energy storage lithium batteries

Do lithium-ion batteries need thermal management?

Thermal management of lithium-ion batteries for EVs is reviewed. Heating and cooling methods to regulate the temperature of LIBs are summarized. Prospect of battery thermal management for LIBs in the future is put forward. Unified thermal management of the EVs with rational use of resources is promising.

Why is temperature important for lithium-ion battery electric vehicles?

However, temperature of the battery has become one of the most important parameters to be handled properly for the development and propagation of lithium-ion battery electric vehicles. Both the higher and lower temperature environments will seriously affect the battery capacity and the service life.

What is liquid cooling in lithium ion battery?

With the increasing application of the lithium-ion battery, higher requirements are put forward for battery thermal management systems. Compared with other cooling methods, liquid cooling is an efficient cooling method, which can control the maximum temperature and maximum temperature difference of the battery within an acceptable range.

How does temperature affect a lithium ion battery?

Both the higher and lower temperature environments will seriously affect the battery capacity and the service life. Under high temperature environment, lithium-ion batteries may produce thermal runaway, resulting in short circuit, combustion, explosion and other safety problems.

Are lithium-ion batteries a viable alternative to conventional energy storage?

The limitations of conventional energy storage systems have led to the requirement for advanced and efficient energy storage solutions, where lithium-ion batteries are considered a potential alternative, despite their own challenges .

Why are lithium-ion batteries used in electric vehicles?

Lithium-ion batteries (LIBs) have been widely used in energy storage systems of electric vehicles due to their high energy density, high power density, low pollution, no memory effect, low self-discharge rate, and long cycle life [3, 4, 5, 6]. Studies have shown that the performance of LIBs is closely related to the operating temperature [7, 8].
