Abstract:
A battery comprising:an electrode plate unit, including a plurality of positive electrode plates and a plurality of negative electrode plates that are alternately stacked upon one another with intervening separators therebetween, thereby constituting respective groups of positive and negative electrode plates, wherein lateral edges of the positive electrode plates protrude beyond the negative electrode plates on one side, and lateral edges of the negative electrode plates protrude beyond the group of positive electrode plates on the opposite side; collector plates arranged respectively on the lateral edges of the positive and negative electrode plates; and thermal spray metal coatings formed on end surfaces of said respectively protruded lateral edges of the positive and negative electrode plates for integrally joining the positive electrode plates together and the negative electrode plates together, respectively, and for connecting respective collector plates to the positive electrode plates and the negative electrode plates.
