The development trend of lithium battery electrolyte technology

1. High specific energy electrolyte The current pursuit of high specific energy is the biggest research direction of lithium batteries. Especially when mobile devices account for an increasing proportion of people's lives, battery life has become the most critical performance of the battery. 2. High-power electrolyte High-power lithium batteries not only require high solid phase diffusion electrode materials, but also have a short migration path for nano-sized ions, controllable electrode thickness and compactness, and higher requirements for electrolytes. 3. Wide-temperature electrolyte When the battery is at a high temperature, the electrolyte itself is easy to decompose, and the side reaction between the material and the electrolyte is intensified. At low temperatures, electrolyte salting out and negative SEI membrane impedance can increase exponentially. 4. Safety electrolyte lithium battery safety is very important in combustion and even explosion. First, the battery itself is flammable. Therefore, when the battery is overcharged, overdischarged or short-circuited, when the battery is 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-term electrolyte Due to the technical difficulties in recycling lithium batteries, especially power lithium batteries, extending battery life is a way to alleviate this situation.
