摘要

Conventional liquid electrolyte of Li-ion batteries is highly burnable. There are efforts to replace it with a Li-ion conducting polymer in order to improve the safety. We decided to test the influence of the liquid electrolyte in a real thermal runaway test and to measure the characteristic temperatures, amount and composition of released vent-gas. Here we compare thermal runaway results of (1) a fully charged conventional Li-ion cell and (2) of the same cell but with all electrolyte removed prior to the test by vacuum drying.
