The development trend of lithium ion battery electrolyte technology

　　1. High specific energy electrolyte

　　At present, the pursuit of high specific energy is the biggest research direction of lithium-ion batteries. Especially when mobile devices take up an increasing proportion of people's lives, battery life has become the most critical performance of batteries.

　　2. High power electrolyte

　　High-power lithium-ion batteries not only require electrode materials with high solid phase diffusion, short nanometer ion migration paths, and control electrode thickness and compaction, but also have higher requirements for electrolytes.

　　3. Wide temperature electrolyte

　　When the battery is at a high temperature, the electrolyte itself is easily decomposed, and the side reaction between the material and the electrolyte intensifies. At low temperatures, electrolyte salting out and negative SEI membrane impedance can increase exponentially.

　　4. Safe electrolyte

　　The safety of lithium-ion batteries is mainly reflected in combustion or even explosion. First, the battery itself is flammable. Therefore, when the battery is overcharged, over-discharged or short-circuited, when the battery is punctured and squeezed by the outside, or when the outside temperature is too high, it may cause a safety accident. Therefore, flame retardants are an important research direction for safe electrolytes.

　　5. Long-cycle electrolyte

　　Due to the technical difficulties in recycling lithium-ion batteries, especially power lithium batteries, improving battery life is a way to alleviate this situation.

　　The above is the development status and price trend analysis of lithium-ion battery electrolyte. At present, domestic battery manufacturers have basically realized the localization of electrolyte
