Storing lithium ion batteries at temperatures above 60°C (140°F) can lead to thermal runaway, a dangerous condition where the battery overheats and potentially explodes. On the other hand, extremely cold temperatures below -20°C (-4°F) can cause irreversible damage by affecting the internal chemistry of the battery.

The reaction between zinc oxide and carbon at high temperature can completely remove zinc oxide and consume a part of carbon to improve the mass ratio of Si, in which the generated mesopores can promote the penetration of …
Safe storage temperatures range from 32℉ (0℃) to 104℉ (40℃). Meanwhile, safe charging temperatures are similar but slightly different, ranging from 32℉ (0℃) to 113℉ (45℃). While those are safe ambient air temperatures, the internal temperature of a lithium-ion battery is safe at ranges from -4℉ (-20℃) to 140℉ (60℃).
