CN_113346130_A

Resumen de: US2021320330A1

Disclosed herein is a wide-range temperature electrolyte, a preparation thereof and a lithium ion battery. The wide-range temperature electrolyte includes a glycerin segment, a diisocyanate segment and a segment containing at least two terminal hydroxyl groups and one disulfide bond, and the self-healing electrolyte has a three-dimensional cross-linked network structure. The wide-range temperature electrolyte introduces a large number of repetitive disulfide bond groups and self-complementary hydrogen bond structures into molecules of an electrolyte base material having self-complementary hydrogen bond structures, so as to form the three-dimensional cross-linked network structure. An intermolecular exchange reaction of the disulfide bonds realizes a cross-scale (molecular, micro, and macro-scale) damage sensing response of the electrolyte and a rapid self-healing of the material, and further achieves a multi-level (molecule-component-device-system) self-healing repair function.
