Abstract

A preparation method and application of a titanium nitride fiber-enhanced quasi-solid-state electrolyte, which relates to a synthetic method and application of a solid-state electrolyte. The object of the present disclosure is to solve the problem that the existing polymer electrolyte has low ionic conductivity, poor lithium ion transference number, and insufficient inhibition of lithium dendrite growth. The method includes the following steps: 1. preparation of TiN nanofiber, and 2. preparation of electrolyte. The TiN nanofiber-enhanced electrolyte is used as a solid-state electrolyte of lithium ion batteries. The electrolyte material provided by the present disclosure has excellent rate performance, high cycle stability, and long-term cycle life. In the present disclosure, a TiN nanofiber-enhanced quasi-solid-state electrolyte can be obtained.
