Abstract: The present disclosure provides a battery box, the battery box comprises a box body, batteries, an insulating film and a adhesive. Each battery comprises a case. The insulating film covers the case of each battery and is provided with an opening. The adhesive is provided between the battery and the box body. The A1, A, L1, ρ1, L2 and ρ2 meet a following relationship: L 1 A 1 · ρ 1 · L 2 A - A 1 · ρ 2 L 1 A 1 · ρ 1 + L 2 A - A 1 · ρ 2 ≥ 10  M   Ω . Because the insulating film is provided with the opening, a portion of the adhesive bonds the case to the box body at the opening, a portion of the adhesive bonds the insulating film to the box body at the outside of the opening, it ensures the bonding strength between the battery and the box body. Meanwhile, it makes a covering area of the insulating film on the battery meet the requirement of the insulating strength, thereby ensuring the safety performance.

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.
