Most cyano compounds or their derivatives have excellent physical and electrochemical stability, which can effectively improve the safety and stability of the battery; they can effectively improve the performance of the positive electrode under high voltage conditions, which is of great significance for the research and development of high-voltage lithium-ion batteries.

In recent years, cyano compounds containing disiloxane and silyl ether structural units have been widely studied as non-volatile and environmentally friendly electrolyte solvents.

Using disiloxane cyanide compounds as solvents can effectively avoid corrosion of aluminum current collectors in the presence of LiTFSI, while widening the electrochemical stability window and improving the chemical and thermal stability of the system. Cyano-containing silyl ethers as solvents can also improve chemical and thermal stability. LiTFSI as a lithium salt is well compatible with LiFePO4, LiNi0.33Mn0.33Co0.33O2 and graphite electrode materials.

Compared with carbon, the silicon element in the third period of siloxane solvents has an empty 3d orbital, which can accommodate the lone pair of electrons of oxygen, improve the redox stability of the solvent and reduce the coordination between the solvent and lithium ions.

A particular advantage of silicone liquids is their availability and ease of chemical modification as new low-viscosity electrolyte solvents for lithium-ion batteries. We can use this solvent to combine the high oxidative stability and high ionic conductivity of nitriles with the thermal and environmentally friendly properties of silicone compounds to create a safe and efficient electrolyte using the thermally stable electrolyte salt LiTFSI.
