  Application  

Lithium bisoxalate borate (LiBOB), as a new lithium salt, is an excellent electrolyte and additive in the electrolyte.

1.LiBOB is a coordination chelate capable of forming a stable large π -conjugate system. Anion BOB-with large volume and small lattice energy, more ions can be obtained in the solvent, thus improving the conductivity of the electrolyte system.

2. Because the decomposition temperature of LiBOB is 302℃, LiBOB serves as a blend salt or additive, which improves the thermal stability of the battery at high temperature, reduces the cycle capacity attenuation and the thermal expansion rate of the battery. In the condition of high temperature and high current discharge, the battery performance is significantly improved to meet the demand of electric battery.

3. LiBOB, the additive, which can form a dense SEI film (solid electrolyte interface membrane), at the graphite electrode to better protect the negative electrode. PC in the lithium battery electrolyte will strip off the graphite electrode, especially when the concentration is high, the graphite electrode structure is destroyed and affect the normal charge and discharge of the battery. However, LiBOB co-exist with PC to form an effective SEI film at the graphite electrode, which supports the embedding and detachment of lithium ions, while preventing further redox of the electrolyte, and improves the stability of the electrolyte.

4. As an additive containing boron applied to the lithium ion battery of different cathode materials, the additive will be oxidized preferentially than the electrolyte solvent during the cycle, and the protective film formed will be covered to the surface of the positive electrode. The layer of protective film has good ionic conductivity, can inhibit the electrolyte in the subsequent cycle oxidation decomposition and prevent the damage of cathode material structure. To stable the electrode/electrolyte interface, and ultimately improve the cycle stability of high pressure lithium ion battery.
