20110177375 | REINFORCED BATTERY SEPARATOR - Separators for use in batteries are disclosed. In various embodiments, the separators include one or more of raised shoulders, ribs in three or more sizes, thickened mini-ribs on shoulders, and ribs within the shoulder. The disclosed separators are more resistant to failure due to punctures or tears than conventional separators. | 07-21-2011 |
20120263995 | BATTERY MODULE AND BATTERY PACK - A battery module in which a plurality of cells are aligned includes a holder in which the cells are accommodated, a positive electrode current collector plate which is provided to face positive electrode terminals of the cells and electrically connects the positive electrode terminals, and a negative electrode current collector plate which is provided to face negative electrode terminals of the cells and electrically connects the negative electrode terminals, wherein the holder includes a plurality of accommodation sections, the cells are accommodated in the accommodation sections, a spacer made of an elastic member is disposed between the positive electrode current collector plate and the cells, the spacer further includes an extended portion extending toward the negative electrode terminals of the cells, and an edge of the extended portion close to the negative electrode terminals touches the negative electrode current collector plate. | 10-18-2012 |
20140038027 | BATTERY - A battery includes: a cylindrical battery case; and an electrode body disposed in the battery case, and including a positive plate, a negative plate, and a separator disposed between the positive plate and the negative plate. A spacer formed of a dense body and an electrolyte storage space storing an electrolyte are provided between the electrode body and the battery case on one end or both ends of the battery case in an axial direction of the electrode body. | 02-06-2014 |
20150295217 | SECONDARY BATTERY - A secondary battery includes a contact portion on a bottom retainer that contacts a bottom of a case, thus performing a tension function. The secondary battery includes an electrode assembly having a first electrode, a second electrode, and a separator between the first and second electrodes; a case accommodating the electrode assembly therein, having a top and a bottom and an opening in the top of the case; a cap plate closing the opening of the case; a bottom retainer on an upper surface of the bottom of the case, the bottom retainer including a support portion supporting the electrode assembly and at least one contact portion contacting the bottom of the case. As such, the contact portion may absorb external shocks, thus increasing durability and enhancing safety of the secondary battery. | 10-15-2015 |
429147000 | Projections are deformed portions, of a sheet material, i.e., corrugations, etc. | 1 |
20120219843 | COMPOSITION, ENERGY STORAGE DEVICE, AND RELATED PROCESSES - A positive electrode composition is provided. The positive electrode composition includes at least one electroactive metal selected from the group consisting of titanium, vanadium, niobium, molybdenum, nickel, cobalt, chromium, manganese, silver, antimony, cadmium, tin, lead, iron, and zinc. The composition further includes sodium iodide, present in an amount in a range from about 0.1 weight percent to about 0.9 weight percent, based on the weight of the positive electrode composition; a first alkali metal halide; and an electrolyte salt comprising a reaction product of a second alkali metal halide and an aluminum halide, wherein the electrolyte salt has a melting point of less than about 300 degrees Celsius. Related devices, such as a UPS device, also form embodiments of this invention. | 08-30-2012 |
