Disclosed is a non-lead conductive cap for a battery terminal and battery. The battery may comprise a battery housing and a positive and negative terminal, the positive and negative terminal being accessible through the battery housing; wherein the positive and negative terminal further comprise an electrically conductive cap mounted on both the positive and negative terminal, wherein the electrically conductive cap does not comprise lead.

A battery cell has an electrical fuse. The electric fuse is a fusible link which is arranged on a terminal on an outside of a housing of the battery cell. The fusible link is covered by a polymer.

A secondary battery according to one or more embodiments of the present disclosure includes a case for accommodating an electrode assembly in an internal accommodating space, a cap plate, a first terminal inserted into the cap plate in a first direction, and bent at an inner surface of the cap plate to be coupled to the cap plate, and a collector plate in the case, electrically connected to a first electrode of the electrode assembly, and coupled to the first terminal in the first direction.

A battery terminal bushing is disclosed. The battery terminal bushing comprises a body having an insertion end and an exterior end opposite the insertion end. One or more sealing rings surround the body between the insertion end and the exterior end. A terminal post connector segment is provided on the insertion end of the body. An anti-torque pattern is provided on one or more surfaces of the body configured to engage and be contained within the battery housing material. A lead acid battery comprising the battery terminal bushing is also disclosed.

Provided is a battery module. The battery module includes: a plurality of battery cells each including an electrode terminal; and a bus bar connected to the electrode terminals of the battery cells neighboring each other to electrically connect the battery cells, the bus bar including a first bus bar and a second bus bar that are superposed on each other and include different metals, each of the first and second bus bars making conductive contact with the electrode terminals. Therefore, the thermal and electrical characteristics of the bus bar electrically connecting the neighboring battery cells to each other may be improved while improving weldability between the bus bar and electrode terminals.

Disclosed is a battery having a conductive terminal extending beyond a surface of a battery cover, the conductive terminal having an internal portion and an external surface, wherein the internal portion comprises lead and external surface comprises a non-lead conductive material. Further disclosed is a method for producing such a battery.

Disclosed is a lead acid battery including a housing having an exterior. The battery also includes a lead terminal extending through the housing to the exterior of the housing. A coating covers the lead terminal such that there is no exposed lead exterior to the housing.
