The armoring body 50 is constituted by a laminated armoring material in which a heat-resistant resin layer 2 is adhered to a first surface of a metal foil layer 4 and a thermal fusion resin layer 3 is adhered to a second surface of the metal foil layer 4, and metal exposed sections 54 and 56 in which the metal foil layer 4 is exposed is formed at least on the heat-resistant resin layer 2 side which is an outer side of the laminated armoring material 50.

A rechargeable battery according to an exemplary embodiment of the present invention includes: an electrode assembly including a first electrode, a second electrode, and a separator that is disposed between the first electrode and the second electrode; a case where the electrode assembly is embedded; a cap plate that is coupled to an opening of the case; and a first electrode terminal provided on an upper side of the cap plate and having a first plate terminal that is electrically connected with the cap plate through a fuse portion and a second electrode terminal provided on the upper side of the cap plate and that is electrically connected with the second electrode by penetrating through the cap plate.

A system for managing a battery removal from an electronic device is provided. The electronic device includes a battery interface including multiple battery coupling contacts that engage with battery contacts of the battery in an installed position of the battery. A battery removal detector is configured to detect, based on signals received via the battery interface, an ongoing battery removal process during which first battery contact(s) are disconnected from corresponding first interface contact(s) while second battery contact(s) remain connected with second battery coupling contact(s), and in response, to output a battery removal signal. The system also includes a controller that receives the battery removal signal and, still during the battery removal process, controls a memory device of the electronic device to prevent or complete a defined operation (e.g., writing of persistent storage keys) prior to completion of the battery removal process, to thereby prevent a corruption of the memory device.

Pouch cell having a positive contact region and a negative contact region, by which contact regions electrical contact can be made with the pouch cell and the pouch cell can be charged and discharged in this way, wherein the pouch cell is of planar design and has a cell top side as well as a cell bottom side which is situated opposite the cell top side, wherein the positive contact region is located exclusively on the cell top side and the negative contact region is located exclusively on the cell bottom side, or vice versa.

A battery structure has structure anode and cathode contacts on a front face and on a rear face. The battery structure includes a battery having battery anode and cathode contacts only on a front face thereof. A film including a conductive layer and an insulating layer jackets the battery. The conductive layer extends over the battery anode and cathode contacts and is interrupted therebetween. Openings are provided in the insulating layer on the front and rear faces of the battery structure to form the structure anode and cathode contacts of the battery structure.

A package structure and its related electricity supply system are disclosed. Two substrates of the package structure are directly or indirectly served as current collectors of the electricity supply system. The sealing frame of the package structure is made of several silicone layers having high moisture-resistance and/or high gas-resistance. Hence, the package structure mentioned may not only provide a novel electrical conduction module to lower the intrinsic impedance of the electricity supply system itself but prevent the moisture and the gas outward from the electricity supply unit inside the package structure as well. Consequently, the electrical performance and safety of the electricity supply system are both improved.

A battery includes a first power generation element, a first outer cover body which encloses the first power generation element, and a first planar electrode having, as principal surfaces, a first connecting surface and a first protruding surface opposite the first connecting surface. The first connecting surface is electrically connected to the first power generation element. The first outer cover body includes a first covering portion provided with a first opening. The first protruding surface protrudes from the first opening toward an outside of the first covering portion. The first covering portion is joined to at least one of the first planar electrode and the first power generation element.

Embodiments of the invention provide a battery pack including a pack body and a plurality of terminals. The pack body has first and second main surfaces that are opposed to each other in a first axis direction, first and second end surfaces that are opposed to each other in a second axis direction orthogonal to the first axis direction, and first and second side surfaces that are opposed to each other in a third axis direction orthogonal to the first axis direction and the second axis direction. The plurality of terminals includes a positive terminal, a negative terminal, a temperature detection terminal, and a control terminal that are arranged on the first end surface along the third axis direction. The negative terminal is arranged between the temperature detection terminal and the control terminal and closer to the control terminal than the temperature detection terminal.
