Description

Lithium trifluoromethanesulfonate can be used in lithium battery organic electrolyte lithium salt, reaction catalyst and ionic liquid.

Advantages

With the rapid development of lithium-ion batteries, the demand for electrolytes of lithium-ion batteries is also rapidly increasing. In order to meet the needs of the future development of the lithium-ion battery industry, it is necessary to develop high-safety, high-environmentally compatible power battery electrolyte materials. Although LiPF6 is recognized as an ideal electrolyte for lithium-ion batteries, its synthesis process is complex and its decomposition temperature is low. A small amount of decomposition starts at 60°C. At higher temperatures or in harsh environments, the proportion of decomposition greatly increases, resulting in Free acids such as HF acidify the electrolyte, which ultimately leads to damage to the electrode material and a sharp deterioration in battery performance. Lithium trifluoromethanesulfonate has lower electrical conductivity and electrochemical stability than LiPF6, but its thermal stability, water absorption decomposition, and cycle performance are higher than LiPF6. When it is applied to a solid electrolyte, its stable anions will cause The structure and composition of the passivation layer between the interface of the electrolyte and the negative electrode material are improved, which is beneficial to the stability of the electrolyte, the passivation film, and the electrode.
