Appreciated, a sub cell consists of an anode-separator-cathode triplet. All but the smallest cells consist of many paralleled sub cells. It's like that for more than 100 years.

Sub cells shortens --> cell short + heat. Sub cell opens --> reduced cell capacity and increased inner resistance with potential for cell reversal.

Important here is that BMS+charger look after the cells, keeping them in their operating envelope and mitigate cell faults.

Mitigate: DISCONNECT charger on any cell fault. When in doubt, do not charge.
