▎ 摘　　要

NOVELTY - Thermochromic paint comprises graphene particles, diacetylene materials, organic solvents and dispersants, where the mass-volume ratio of diacetylene material and organic solvent is 1-10 mg/ml, the mass ratio of graphene and diacetylene is 0.02:1-0.5:1, and the mass ratio of diacetylene and dispersant is 0.1:1-1:1. USE - Used as the thermochromic paint. ADVANTAGE - The paint: has temperature-sensitive and color-changing function, has good thermal conductivity; and can be coated to cells of the battery module through a series of structural designs. The battery module: is convenient for the staff to conduct daily and quick inspections, and is convenient for timely detection of faulty modules. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for battery module with high temperature warning function comprising module housing and batteries installed inside the module housing. The outer appearance of the battery cell includes warning coating of the thermochromic paint. An observation area is set on the module housing, through which the warning coating can be seen. DESCRIPTION OF DRAWING(S) - The diagram shows a schematic representation of the battery module with high temperature warning function.
