Analyze the technology and development trends of lithium-ion battery electrolytes

1. High specific energy electrolyte

The pursuit of high specific energy is the biggest research direction of lithium-ion batteries at present, especially when mobile devices occupy an increasing proportion in people's lives, battery life has become the most critical performance of batteries.

2. High-power electrolyte

At present, it is difficult for commercial lithium-ion batteries to achieve high-rate continuous discharge, an important reason is that the battery tabs are seriously heated, and the internal resistance leads to the overall temperature of the battery being too high, which is prone to thermal runaway. Therefore, the electrolyte should be able to prevent the battery from heating up too quickly while maintaining high conductivity. As for power lithium batteries, fast charging is also an important direction for the development of electrolytes.

3. Wide temperature electrolyte

At high temperature, the battery is prone to the decomposition of the electrolyte itself and the aggravation of the side reaction between the material and the electrolyte. At low temperatures, electrolyte salting out and negative electrode SEI membrane impedance may be doubled. The so-called wide temperature electrolyte is to make the battery have a wider working environment.

4. Safety electrolyte

The safety of the battery is important in combustion and even explosion, first of all, the battery itself is flammable, so when the battery is overcharged, overdischarged, short-circuited, when receiving acupuncture and extrusion from the outside world, when the outside temperature is too high, it may cause safety accidents. Therefore, flame retardant is an important direction in the research of safe electrolytes.

5. Long-cycle electrolyte

Because there are still great technical difficulties in the recycling of lithium-ion batteries, especially power lithium batteries, improving the life of batteries is a way to alleviate this situation.
