Battery contact with surface texturing. Exemplary battery contacts are located within a battery pack. The battery pack is operable to provide power to a device through a device contact of the device. The battery pack includes a battery pack housing, at least one battery cell located within the battery pack housing, and battery contacts including a positive terminal and a negative terminal. The battery contacts are configured to engage the device contact of the device and allow electric current to transfer from the battery pack to the device. The battery contacts define a surface having a surface texture. The surface texture includes raised portions for contacting the device contact to allow electric current to transfer from the battery pack to the device. The surface texture also includes recessed regions spaced away from the surface and for providing a space between the battery contacts and the device contact.

An electrical connection comprises a first conductor and a second conductor electrically connected to the first conductor. The first conductor has a first contact section with a first contact face laterally delimited by a first side face. The second conductor has a second contact section with a second contact face surrounded by a rim having a second side face. The second side face limits a contact space above the second contact face and the first contact face is arranged on the second contact face. A reservoir space is arranged between the first side face of the first contact face and the second side face of the rim, the reservoir space surrounds the first contact face and a sealing material is arranged in the reservoir space. The sealing material forms a sealing ring that seals an interface between the first contact face and the second contact face.

A secondary battery includes: an electrode assembly; a case accommodating the electrode assembly; an electrode tab extending from the electrode assembly; a sealing part for insulating the electrode tab from the case; and an insulation film around the electrode tab and between the sealing part and the electrode assembly.

Corrosion mitigation in a battery may include displacing a first flowable medium with a second flowable medium along a first electrode to interrupt fluid communication of the first flowable medium with the first electrodethus interrupting operation of the batterywhile a second electrode remains in contact with a flowable medium (e.g., one or more of the first flowable medium or another flowable medium, such as a gel). For example, a membrane (e.g., an underwater oleophobic material) may be disposed between the first electrode and the second electrode. An oil may displace an aqueous electrolyte on a first side of the membrane toward a metallic electrode while the aqueous form of the electrolyte remains in contact with an air electrode on a second side of the separator membrane disposed toward the air electrode.

A bus bar terminal includes an electrode connection portion that connects electrode terminals of power storage elements to each other, and a wire connection portion that is to be connected to an electrical wire, and guide portions are provided between the electrode connection portion and the wire connection portion, the guide portions guiding adhered liquid so as to fall to a position separated from the wire connection portion.

A laminate-type power storage element, including an exterior body that is formed in a flat bag shape, and an electrode body that has a sheet-shaped positive electrode and a sheet-shaped negative electrode layered via a separator and that is sealed inside the exterior body together with an electrolytic solution, wherein electrode terminal plates of the positive electrode and the negative electrode are guided in an identical direction from a predetermined margin of the exterior body to an outside of the exterior body, and a support part that is made with a film shaped resin having insulating and heat-resistant properties is formed on principal surface sides of the electrode terminal plates at a region that is along the predetermined margin and covers up to tip ends of the electrode terminal plates.

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 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.

Provided are an electrode lead wire member including a sealing film having high adhesive strength and resistance to an electrolytic solution, and a battery including the electrode lead wire member. Provided is an electrode lead wire member including: a derivation portion extending in one direction; a surface-treated layer formed, at the derivation portion, on a surface of the derivation portion; and a sealing film provided in contact with the surface-treated layer, in which the sealing film has an adhesive resin layer in contact with the surface-treated layer, and the adhesive resin layer contains imine-modified polyolefin or modified polyolefin having a carbodiimide group.

The present disclosure relates generally to the field of batteries and battery modules, and more specifically, relates to a system and method for manufacturing terminal assemblies for lithium-ion battery modules. A disclosed battery module includes a terminal block assembly that is secured to a polymer housing of the battery module. The terminal block assembly includes a terminal post having a post portion and a base portion that extends outward from a central axis of the post portion. The terminal block assembly also includes a bus bar coupled to the base portion of the terminal post without welding, wherein the bus bar includes a trough disposed near the terminal post. The terminal block assembly further includes a polymer portion overmolding at least the trough of the bus bar to form a drainage channel near the terminal post.
