1results about How to "Smooth migration" patented technology

This invention belongs to the field of lithium-ion battery technology, and relates to a flame-retardant gel electrolyte, its preparation method, and a lithium-ion battery containing the electrolyte. The flame-retardant gel electrolyte is a gel structure in which a cross-linked gel network encapsulates a basic electrolyte. It has an ionic conductivity ≥0.50 mS / cm, a self-extinguishing time ≤2s, a thermal runaway temperature ≤1000℃, and a mass retention rate ≥40% after thermal runaway. This flame-retardant gel electrolyte achieves excellent flame-retardant performance through its cross-linked gel network structure. The self-extinguishing time ≤2s can quickly prevent flame spread, and the thermal runaway temperature ≤1000℃ and mass retention rate ≥40% after thermal runaway significantly improve battery thermal safety. Simultaneously, the high ionic conductivity ≥0.50 mS / cm ensures smooth ion migration during charging and discharging, reduces battery polarization, and improves charging and discharging efficiency and cycle stability.
