LEAF SPRING CONNECTOR FOR LITHIUM-ION BATTERY CELLS

The present disclosure describes a non-welded leaf spring battery cell connector which allows for unrestricted outgassing during Lithium-Ion thermal runaway. The connector also has a low-resistance electrical connection surface for applications with rough, uneven contact surfaces such as those on refurbished Lithium-Ion battery cells. The connector is compatible with both protected and unprotected Lithium-Ion cells, as it allows for up to about 5 mm of vertical travel to support varying battery cell lengths caused by battery protection circuits. The leaf spring connector for Lithium-Ion battery cells is made of a conductive sheet of metal, cut and folded into a leaf-spring connector for a removable, non-welded battery cell. The leaf spring connector has one or more areas of material removed, as to not block the flow of caustic gasses during emergency outgassing.
