WebHere we report in situ measurement of temperature distributions in a 2.5-Ah pouch format Li-ion cell during internal short circuit (ISC) and thermal runaway. The ISC and thermal runaway were triggered by nail penetration. The local temperatures were measured by embedded K type micro thermocouples in the middle layer of the experimental Li-ion cell. WebClose, the cathode reaction is: $$ \ce{LiFePO4 -> FePO4 + Li^+ + e^-}$$ The anode is: $$\ce{Li^+ + C6 + e^- -> LiC6}$$ The best description I can give is that the lithium ion intercalates into the graphite and "steals" some electron density from the six-membered conjugated ring.
