Can lithium-ion batteries be overcharged?

In a lithium-ion battery,

overcharging can create unstable conditions inside the battery, increase pressure, and cause thermal runaway

. Lithium-ion battery packs are required to have a protection circuit to prevent excessive pressure build-up and cut off the flow of ions when the temperature is too high.

What is battery stack?

In a battery stack,

single cells can be arranged in parallel and in series in order to achieve the required capacity and operating voltage

(up to 1 kV or higher). Battery manufacturers attempt to provide stacks with identical cells, but this is not physically possible.
