Abstract
Official abstract text for this publication.
A battery, includes: electrode body including positive and negative electrodes being alternately layered in a first direction with separator provided therebetween. The positive electrode current collector has a first burr and the negative electrode current collector has a second burr. In the battery, either the following (A) or (B) is satisfied: (A) plural first burrs do not include a pair of first burrs in which protrusion directions of adjacent first burrs differ, and plural second burrs do not include a pair of second burrs in which protrusion directions of adjacent second burrs differ; or (B) plural first burrs include only one pair of first burrs in which protrusion directions of adjacent first burrs differ, and plural second burrs include only one pair of second burrs in which protrusion directions of adjacent second burrs differ.
First claim
Opening claim text (preview).
What is claimed is: 1 . A battery, comprising: an electrode body including a plurality of positive electrodes each including a positive electrode current collector, and a plurality of negative electrodes each including a negative electrode current collector, the plurality of positive electrodes and the plurality of negative electrodes being alternately layered in a first direction with a separator provided therebetween; a laminate exterior body accommodating the electrode body; a first tab projecting from the laminate exterior body toward one side in a second direction that is orthogonal to the first direction, the first tab electrically connected to a plurality of the positive electrode current collectors; and a second tab projecting from the laminate exterior body toward another side in the second direction, the second tab being electrically connected to a plurality of the negative electrode current collectors, wherein the positive electrode current collector has a first burr projecting toward the first direction at an edge at a side of the second tab, wherein the negative electrode current collector has a second burr projecting toward the first direction at an edge at a side of the first tab, and wherein either the following (A) or (B) is satisfied: (A) plural first burrs do not include a pair of first burrs in which protrusion directions of adjacent first burrs differ, and plural second burrs do not include a pair of second burrs in which protrusion directions of adjacent second burrs differ; or (B) plural first burrs include only one pair of first burrs in which protrusion directions of adjacent first burrs differ, and plural second burrs include only one pair of second burrs in which protrusion directions of adjacent second burrs differ. 2 . The battery of claim 1 , further comprising a plurality of electrically insulating members covering each of the first burrs and the second burrs. 3 . The battery of claim 1 , wherein (A) is satisfied. 4 . The battery of claim 1 , wherein (B) is satisfied.
