When the lithium-ion battery is subjected to mechanical abuse, the internal layer structure will be damaged, which leads to internal short circuit and is manifested as voltage reduction and temperature increase [144]. For multi-physical field simulation of mechanical abuse of LIBs, the mechanical failure criterion acts as a bridge between ...
18650 Battery Voltage: 11 Things You Need to Know
Yes, an 18650 3.7V lithium-ion battery can use a 4.2V charger because 4.2 volts is the standard charging voltage for most lithium-ion batteries when they are fully charged. The nominal voltage of these batteries, which is typically listed as 3.7V, refers to their average or operating voltage during use, not the charging voltage.
