Advantages and disadvantages of organic and inorganic electrolytes in lithium-ion batteries

Advantages of organic electrolytes:

It can achieve high conductivity, which helps to improve the energy density of the battery;

Has high chemical stability and durability, which can improve the cycle life of batteries;

Lower viscosity is beneficial for mass transfer in batteries;

It can maintain high conductivity at low temperatures, that is, work in extreme temperature environments.

Disadvantages of organic electrolytes:

Compared to inorganic electrolytes, organic electrolytes are more susceptible to the influence of chemical reactions;

Flammable at high temperatures, with relatively poor safety;

Some organic electrolytes may decompose after prolonged operation, reducing the performance of the battery;

The advantages of inorganic electrolytes:

Compared to organic electrolytes, inorganic electrolytes have more chemical stability and can reduce battery losses;

Inorganic electrolytes have better thermal stability and relatively higher safety;

At room temperature, the viscosity of inorganic electrolytes is lower and mass transfer is easier.

Disadvantages of inorganic electrolytes:

Easy to form large electrochemical inert interfaces, hindering ion migration;

The limited electrochemical window limits its potential voltage range;

The poor selection of some inorganic electrolytes may lead to solid-state retention of the electrolyte, ultimately affecting the performance of the battery.
