Abstract: A lithium-ion battery module has a housing and a plurality of lithium-ion battery cells disposed in the housing. Each of the plurality of lithium-ion battery cells includes a first terminal with a first polarity, a second terminal with a second polarity opposite to the first polarity, an overcharge protection assembly, and a casing electrically coupled to the first terminal such that the casing has the first polarity, where the casing has an electrically conductive material. The lithium-ion battery module also includes a vent of the overcharge protection assembly electrically coupled to the casing and a conductive component of the overcharge protection assembly electrically coupled to the second terminal, and the vent is configured to contact the conductive component to cause a short circuit and to vent a gas from the casing into the housing when a pressure in the casing reaches a threshold value.
