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.

Abstract: This application provides an apparatus and method for detecting tab folds, and an image analyzer. The apparatus for detecting tab folds includes: a first image obtaining module, configured to obtain a first image of a first lateral face of tabs of a battery cell; a second image obtaining module, configured to obtain a second image of a second lateral face of the tabs, where the second lateral face is different from the first lateral face; and an image analyzer, configured to obtain, based on the first image, a first number of layers of the tabs corresponding to the first lateral face, and obtain, based on the second image, a second number of layers of the tabs corresponding to the second lateral face, and determine, based on at least one of the first number of layers or the second number of layers, whether the tabs are in a folded state.
