description:
LiFSI Powder has good solubility in common organic solvents and can be fully mixed with solvents and other components in the electrolyte to improve the uniformity and stability of the battery's electrolyte. LiFSI electrolyte has good compatibility with the two main components of SEI film, and only replaces some of its components at 160°C. LiFSI can make up for the deficiency of LiPF6 and is a better quality electrolyte solvable lithium salt.

FAQ
Q.What is LiFSI powder?
A.LiFSI Powder, or lithium bis(fluorosulfonyl)imide, is a new type of lithium salt with the chemical formula LiN(SO₂F)₂. It features high electrical conductivity, excellent chemical and thermal stability, and can enhance the cycle performance and safety of lithium batteries. With broad application prospects in power batteries, energy storage batteries and other fields, it is a potential material to replace the traditional lithium salt LiPF₆.
Q.The function of LiFSI powder
A.LiFSI powder (difluorosulfonic acid lithium powder) is a key electrolyte material for lithium batteries. As a core component, LiFSI powder can significantly enhance the electrical conductivity and chemical stability of the electrolyte. During the battery cycling process, LiFSI powder can improve the cycle life and high-temperature safety of the battery, effectively reducing electrolyte decomposition. At the same time, LiFSI powder is compatible with high-voltage positive electrode materials, providing strong support for the research and development of high-energy-density batteries, making LiFSI powder play a significant role in fields such as power batteries and energy storage batteries, and becoming the focus of industry attention.
