How does a polymer protect a battery from overcharging?

Once the potential rises up to the oxidation potential of electroactive polymer, the polymer transforms from an electronically insulating state to a highly conductive state, owing to the oxidative doping (i.e. p-doping), thus creating a current bypass to protect the battery from overcharging.

Additionally, the battery protection circuit manages current rushing into and out of the battery, such as during pre-charge or hotswap turn on.

What happens if a battery is overcharged?

During normal charging and discharging, the electroactive polymers is in the intrinsic electronically insulating state and the polymer membrane functions as a conventional separator to conduct ions through its porous channels. When the battery is overcharged, its cathode potential undergoes a rapid rise.
