A lithium ion (Li-ion) battery module includes a module terminal configured to electrically couple the Li-ion battery module to an electrical connector of an external load. The module terminal includes a conductive component and a sealing shim secured to the conductive component, the sealing shim being formed from a polymeric material. The Li-ion battery module includes a housing containing a plurality of Li-ion battery cells and having an opening through which the conductive component of the module terminal at least partially protrudes. The sealing shim of the module terminal is directly secured to the housing and forms a seal isolating an interior of the housing from the external environment.

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.

A conductive sheet and a battery conducting module, wherein the battery conducting module is adapted to electrically connect electrodes of a plurality of batteries which are arranged side by side, and includes two conductive sheets. Each of the conductive sheets includes a connecting portion, two first conducting portions, and two second conducting portions. The connecting portion has a first side and a second side. The two first conducting portions are spaced from each other by a distance and are connected to the first side, and extend along a first direction. The two second conducting portions are spaced from each other by a distance and are connected to the second side, and extend along a second direction. The second direction is opposite to the first direction. The conductive sheets are respectively adapted to connect the electrodes of batteries and are disposed facing each other.

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 connection pole for a rechargeable battery. The connection pole has a connection region for securing a pole terminal to the connection pole, and a securing region for securing the connection pole to a housing part of the rechargeable battery. A circumferential projection is provided in an end region of the securing region facing towards the connection region, said projection having at least substantially an annular shape and being provided with a tooth system on its outer circumference for the purpose of prevention rotation of the connection pole. A circumferential sealing projection is provided, in the end region of the securing region facing towards the connection region, between the circumferential projection provided with the tooth system and the connection region, said sealing projection being of at least substantially circular-ring shaped design.

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.

A battery terminal includes a penetration plate arranged to penetrate from one end portions of annular portions to the other end portions interposing slits, a fastening bolt supported to be rotatable around an axial direction by a threaded hole provided on the other end portion of the penetration plate, and a spacer arranged in contact with the annular portions from the other end portion side of the penetration plate and converting a tightening force in the axial direction arising along with the rotation of the fastening bolt around the axial direction into a pressing force that presses the annular portions from a long-side direction. The penetration plate is arranged to penetrate a clearance of the pair of annular portions. The pair of annular portions includes projecting portions as a clearance reduction portion that reduces the clearance in at least a part of the penetration area of the penetration plate.

A vehicle traction battery assembly including a battery cell, a busbar, and a thermal spray is provided. The battery cell may include a terminal having an angled taper upper portion extending therefrom. The busbar may define a through-hole having a taper defining an angle substantially opposite of the angled taper upper portion such that a cavity is defined therebetween when the terminal extends through the through-hole. The thermal spray may be deposited within the cavity to secure the busbar to the terminal. The thermal spray may be formed from a metallic powder selected to include particles that deform and connect when accelerated to a speed of approximately 500 mph or more to join the particles and form a bond securing the terminal to the busbar. The particles of the metallic powder may be iron, copper, aluminum, nickel, iron, or magnesium.
