BATTERY CASE AND SECONDARY BATTERY WITH SAID BATTERY CASE

To provide a battery case capable of appropriately preventing the thermal influence between a plurality of electrode bodies in a secondary battery provided with the electrode bodies.SOLUTION: A battery case 30 including a box-shaped case body 32 for accommodating an electrode body 10 including a positive electrode 50 and a negative electrode 60 includes a plurality of electrode body accommodating spaces 36 capable of accommodating a plurality of electrode bodies 10 in parallel, and a space provided between the plurality of electrode body accommodating spaces 36, which is a heat insulating space 38 capable of accommodating a heat insulating element 80. As a result, it may be difficult for the heat of one electrode body in the same battery case 30 to be transferred to the other electrode body.SELECTED DRAWING: Figure 3 【課題】複数の電極体を備える二次電池において、電極体同士の熱影響を適切に防止し得る電池ケースを提供する。【解決手段】正極５０および負極６０を含む電極体１０を収容するための箱型のケース本体３２を備える電池ケース３０であって、前記電極体１０を複数個並列に収容可能な複数の電極体収容空間３６と、前記複数の電極体収容空間３６それぞれの間に設けられた空間であって、断熱要素８０を収容可能な断熱空間３８と、が設けられている。これにより、同じ電池ケース３０内の一の電極体の熱が他の電極体へ伝わりづらくなり得る。【選択図】図３
