"From an electrical engineering standpoint, that makes no sense. Thermal runaway starts when too much power is being drawn from the batteries and they begin to overheat until exploding or melting, their promixity to each other may limit the damage of an overloaded or malfunctioning cell, however the core problem remains, why are 787 electronic systems overloading the batteries?"
"If one cell explodes or melts, you still essentially have a fire in progress. Protecting the other cells buys you time, but how much time do you have when there is fire on a plane?"
"Obviously its a design issue, probably very complex that Boeing simply doesnt have the time and money to investigate thoroughly."
"So this is a patch. Nothing I have read indicates an engineering approach was taken to prevent the previous result."
