Abstract
The present disclosure provides a battery module. The battery module comprises: a plurality of mono-batteries arranged along an arrangement direction; and a frame receiving and fixing the plurality of mono-batteries. The battery module further comprises a plurality of isolating plates, each isolating plate is interposed between two adjacent mono-batteries, each isolating plate is provided with a through hole penetrating along the arrangement direction. Each isolating plate is configured to be capable of self-foaming to make a volume of each isolating plate expanded when each isolating plate is heated and a temperature of each isolating plate is more than 200° C. When one mono-battery suffers thermal runaway, the through hole of each isolating plate can form air thermal resistance, thereby preventing heat generated by the runaway mono-battery from massively and quickly transferring to the large surfaces of the adjacent mono-batteries, so as to achieve the purpose of thermal isolation.
