Zusammenfassung:Disclosed in the present invention is a battery module or the like, which has an improved structure to ensure safety. A battery module according to an aspect of the present invention comprises: a cell assembly having one or more battery cells; a module case accommodating the cell assembly in an inner space and having a venting hole through which gas in the inner space is discharged to the outside; a filtering member provided in the venting hole of the module case and configured to filter foreign matters from being introduced into the inner space from an outer space through the venting hole; and a plurality of mesh members respectively configured in a mesh form, and provided on both sides of the filtering member. La présente invention concerne un module de batterie ou similaire, qui a une structure améliorée pour garantir la sécurité. Un module de batterie selon un aspect de la présente invention comprend : un ensemble d'éléments ayant un ou plusieurs éléments de batterie ; un compartiment de module recevant l'ensemble d'éléments dans un espace interne et ayant un trou d'aération à travers lequel un gaz dans l'espace interne est évacué vers l'extérieur ; un élément de filtration disposé dans le trou d'aération du compartiment de module et configuré pour filtrer des matières étrangères d'être introduites dans l'espace interne à partir d'un espace externe à travers le trou d'aération ; et une pluralité d'éléments de maille respectivement configurés sous une forme de maille, et disposés sur les deux côtés de l'élément de filtration. 본 발명은 안전성이 확보될 수 있도록 구조가 개선된 배터리 모듈 등을 개시한다. 본 발명의 일 측면에 따른 배터리 모듈은, 하나 이상의 배터리 셀을 구비하는 셀 어셈블리; 내부 공간에 상기 셀 어셈블리를 수용하고, 내부 공간의 가스가 외부로 배출되도록 벤팅 홀이 형성된 모듈 케이스; 상기 모듈 케이스의 벤팅 홀에 구비되어, 외부 공간으로부터 상기 벤팅 홀을 통해 상기 내부 공간으로 이물질이 유입되는 것을 필터링하도록 구성된 필터링 부재; 및 각각 메쉬 형태로 구성되며, 상기 필터링 부재의 양측에 구비된 다수의 메쉬 부재를 포함한다.
