How to judge the environmental adaptability of lithium-ion batteries?

Environmental adaptation

(1) High-temperature baking: Place the monomer battery in a high-temperature explosion box to (5 ± 2? C) / min warming rate heated to 130 °C, at which temperature insulation 10 min.

(2) High-temperature storage: placing a single cell or battery at 75 ± 2? Coven holds 48h, batteries should, should not leak, do not deflate, do not break, do not fire, do not explode.

(3) Low pressure:(UL standard).

Unsuitable temperatures will trigger other chemical reactions within the lithium-ion battery to produce compounds that we do not want to see, so there is a protective thermostat diaphragm or electrolyte additive between the positive and negative poles of many lithium-ion batteries. When the battery heats up to a certain point, the composite membrane hole is closed or the electrolyte is denatured, the resistance in the battery increases until the circuit is broken, and the battery is no longer heated to ensure that the battery charging temperature is normal.
