摘要： A rechargeable lithium-ion button cell battery having a sealed housing includes a top flat plate and a round or oval cup sealed by laser at the rim of top plate whereas connecting the opening end of the cup sidewall. The top plate has a centered sandwiched structure including two outer plates at upper and lower position, that clamping one inner pin-like conductive plate by its flange, insulated by a gasket. The upper plate of the outer plates has an asymmetric shape to its center line, which allows asymmetric sealing force applied on the inner pin-like plate flange to act as a safety vent. Inside the sealed housing the anode and cathode electrodes are either spiral wound or stacked with separator to be a round or oval roll, one electrode is connected to the cup, the other electrode is connected to the inner pin-like conductive plate of the top plate.

摘要： A rechargeable lithium ion button cell battery having a sealed housing comprises an inner casing and an outer casing , both casings have at least one flat area as top or bottom of the battery, and a round or oval sidewall vertically formed to the flat area. An insulation gasket is positioned between said sidewalls, and the outer casing opening is mechanically crimped to complete the seal of the battery. Inside the sealed housing the anode and cathode electrodes are spiral wound with separator to be a round or oval roll. Said roll axis is vertical to the said flat areas of the casings. The two electrodes are tapered in width to fully utilize the inner space. The electrodes comprise current collectors of metal foils coated with lithium-intercalating active materials, leaving small area of uncoated metal foils as conductor tabs for connecting the electrodes to the casings. The tabs could be welded or by tight contacting to the casings, in several options. Insulation washers or tapes are applied to the naked metal surfaces of the electrodes or casings inside of the housing to prevent short circuit and enable the battery to have longer cycle life.
