AI Technical Summary
Technical Problem
In existing technologies, the separator is prone to rapid chemical reactions under abnormal battery conditions, leading to battery fires, and is difficult to effectively prevent.
Method used
An internal resistance adjustment mechanism is set on the surface of the diaphragm. The coverage area of the diaphragm is adjusted by airbags or baffles to control the passage of electrolyte ions and achieve controllable adjustment of internal resistance.
Benefits of technology
In abnormal conditions, the internal resistance mechanism is adjusted to make the separator present a high internal resistance state, thereby avoiding rapid chemical reactions in the battery and improving battery safety.
