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.
