Abstract
A battery including an electrode unit which is an electricity generating element housed in a battery can, in which the electricity can be taken out of the can via a pair of negative and positive electrode terminals which are exposed outside the can, and one of the negative and positive electrode terminals has a coating layer formed on a surface thereof that is the same material as the material of which the other of the negative and positive electrode terminals is made.
Claims7
A battery comprising an electrode unit which is a power generation element housed in a cylindrical battery can, and in which electricity can be taken out from a pair of negative and positive electrode terminals which are exposed outside the can, wherein a coating layer consisting of the same material of which one of the negative and positive electrode terminals is made is formed on a surface of the other of the negative and positive electrode terminals and the coating layer is formed by a cladding connection or plating on the surface of said other electrode terminal.
A combination of at least two batteries connected in series in which each battery is the same and comprises an electrode unit which is a power generation element housed in a cylindrical battery can, and in which electricity can be taken out from a pair of negative and positive electrode terminals which are exposed outside the can, wherein a coating layer consisting of the same material of which one of the negative and positive electrode terminals is made is formed on a surface of the other of the negative and positive electrode terminals, and further wherein the at least two batteries connected in series are connected so that the negative electrode terminal of one battery directly contacts the positive electrode terminal of the other battery.
