THERMAL RUNAWAY SUPPRESSION AGENT

Title:

THERMAL RUNAWAY SUPPRESSION AGENT

Document Type and Number:

WIPO Patent Application WO/2019/181704

Kind Code:

A1

Abstract:

The present invention addresses the issue of providing a non-aqueous electrolyte secondary battery that has no thermal runaway if an internal short-circuit occurs and no risk of fire or explosion, without increasing size or greatly increasing cost. This agent for suppressing thermal runaway caused by internal short-circuits is for a non-aqueous electrolyte secondary battery having: a positive electrode including a positive electrode active substance comprising a silyl ester compound; a negative electrode including a negative electrode active substance, and a non-aqueous electrolyte. In this suppression method for thermal runaway caused by internal short-circuits in non-aqueous electrolyte secondary batteries, 0.01%–10% by mass of the agent for suppressing thermal runaway caused by internal short-circuits, for use in non-aqueous electrolyte secondary batteries, is mixed with the non-aqueous electrolyte.
