Abstract
A stacked nonaqueous electrolyte battery, a method of manufacturing the battery, and a stacking apparatus for the battery are provided. The stacked nonaqueous electrolyte battery includes a plurality of electrode bodies alternately stacked, each of the electrode bodies including an anode and a cathode laminated through a separator. The separator has a raised edge portion leading along an edge portion of one of the anode and the cathode, and the raised edge portions of the plurality of the separators overlap one another.
Claims23
A stacked nonaqueous electrolyte battery comprising:
- a plurality of anodes and cathodes alternately stacked and isolated by separators,
- wherein the separators have raised edge portions along an edge portion of one of the anodes and cathodes, and the raised edge portions of a plurality of the separators overlap one another.
A method of manufacturing a stacked nonaqueous electrolyte battery composed of a plurality of anodes and cathodes alternately stacked and isolated by separators, the method comprising:
- stacking the anode or cathode, and the separator such that an edge portion of the separator is raised;
- holding a state of the raised edge portion of the separator to fabricate a battery element;
- and
- packaging the battery element with a packaging material;
- wherein the stacking step is performed by repeating the following steps a plurality of times:
- sucking the anode or cathode;
- sucking the separator while maintaining the suction of the anode or cathode;
- inserting both the anode or cathode and the separator into a contour holding member such that the edge portion of the separator is raised;
- and
- mounting the anode or cathode and the separator together by releasing the suction of both the anode or cathode and the separator.
A stacking apparatus for stacking anodes, cathodes, and separators, comprising:
- a sucking apparatus including:
- an electrode sucking member, provided with a first vacuum mechanism, for sucking at least a peripheral portion of the anode or cathode by the first vacuuming mechanism;
- a separator sucking member, provided with a
- second vacuuming mechanism, for sucking a peripheral portion of the separator by the second vacuuming mechanism;
- and
- a moving member for lowering and elevating the
- electrode sucking member and the separator sucking member together;
- and
- a contour holding member for holding a contour of the anode, the cathode, and the separator, by raising an edge portion of the separator during the stacking of the anode, the cathode, and the separator.
