Overview

Randomized trial demonstrates enhanced thermal safety and electrochemical performance in lithium-ion batteries, indicating a practical pathway for improvements.

Key Points

  • This research aims to develop a multifunctional flame-retardant separator to improve safety and performance in lithium-ion batteries.
  • Introduced a hybrid flame-retardant separator composed of inorganic boehmite and phosphorus-based polymer via vapor-induced phase separation.
  • Evaluated thermal stability and electrochemical performance of the separator under various conditions.
  • The separator maintained ion transport despite the additional layer, with improved cycling stability observed.
  • Thermal shrinkage of the polyethylene substrate was effectively suppressed, enhancing safety.
  • The hybrid separator exhibited excellent flame retardancy due to the interaction of phosphorus and boehmite.
