A cylindrical battery with an opening sealing body that seals an opening of a battery can. The opening sealing body includes a valve member, a metal plate disposed on an inner side of the battery with respect to the valve member, and an annular insulating member interposed between the valve member and the metal plate. The valve member and the metal plate are connected to each other at respective central portions. The valve member has an annular thin-walled portion which is deformable when an internal pressure of the battery increases, and a recessed portion is formed by the thin-walled portion on the insulating member opposing side of the valve member. The insulating member has a section P1 that covers a surface, on the valve member side, of the metal plate, and the section P1 has a rib to be housed in the recessed portion.

Various embodiments described herein relate to a battery that includes a battery cap with one or more cut-out sections. The battery cap may be used to at least partially cover a circuit board that is proximate an end of a battery cell. In various examples, the cut-out sections may be configured to accommodate one or more cell tabs of the battery that protrude above the circuit board.

Disclosed is 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. The connection region is in particular of circular or substantially circular form at least at its end facing the securing region, wherein a circumferential region is provided in an end region, which faces the connection region, of the securing region, which circumferential region at least substantially has a ring shape and, for the purpose of preventing rotation of the connection pole, has on its outer circumference a tooth system projecting radially from the circumferential region. Here, the diameter of the substantially ring-shaped circumferential region is consistently smaller than the diameter of that end of the connection region which faces the securing region.

A system for supplying power to at least one power distribution and data hub using a portable battery pack including a battery enclosed by a wearable and replaceable pouch or skin is disclosed, wherein the pouch or skin can be provided in different colors and/or patterns. Further, the pouch or skin can be MOLLE-compatible. The battery comprises a battery element housed between a battery cover and a back plate, wherein the battery element, battery cover, and back plate have a slight curvature or contour. Further, the battery comprises flexible leads.

A battery cover plate is provided, to resolve problems such as a signal transmission structure and sealing performance of the battery cover plate. The battery cover plate includes a plate body, a battery management unit, and a sensor assembly, wherein the plate body has an outer surface and an inner surface facing away from the outer surface. The battery management unit is disposed in the plate body, wherein a transmission structure is provided between the battery management unit and the outer surface, and the battery management unit includes a wireless communication module. The wireless communication module may perform wireless communication with the outside by using the transmission structure. The sensor assembly is connected to the battery management unit, wherein the sensor assembly is disposed in the plate body and extends out of the inner surface.

A secondary battery includes: an electrode assembly; a case accommodating the electrode assembly; a cap plate sealing the case; and an insulating member between the electrode assembly and the cap plate, and a relationship of M/E=R1 is satisfied, where M is a melting point (° C.) of the insulating member, E is an energy density (Wh/kg) of the secondary battery, and R1 is 0.5 to 3.5.
