Title:
METHOD FOR COLLECTING AND TESTING LITHIUM ION BATTERY THERMAL RUNAWAY PRODUCTS
Document Type and Number:
WIPO Patent Application WO/2020/052286
Kind Code:
A1
Abstract:
A method for collecting and online and offline testing lithium ion battery thermal runaway gas and solid products, which is applicable to collecting and testing thermal runaway products under different parameter conditions, said method comprising: 1) setting a battery thermal runaway condition, and using an electrical heating method to cause, under a set condition, the occurrence of thermal runaway of a battery to be tested; 2) collecting and obtaining gas and solid products after thermal runaway of the battery; 3) testing the gas product collected in step 2); and 4) testing the solid product collected in step 2). Said method takes lithium ion battery thermal runaway products as research objects, and obtains hazard level quantitative data of the lithium ion battery thermal runaway products by using different collecting and testing methods for different environmental atmospheres, different thermal runaway products and different testing forms.
