Abstract
This electrode plate has a strip-like core, a mixture layer formed on both sides of the core, and an exposed section in which the core is exposed, and which is provided so as to be in contact with one short-direction end of the core. The exposed section is provided in mutually opposing positions on both sides of the core and is adjacent to the mixture layer in the short direction and long direction of the core. A lead is connected to the exposed section so as to extend out of one end on either surface of the core. An identification display part by which a manufacturing process history can be identified is formed in the exposed section on either surface of the core.
Claims6
An electrode plate, comprising:
- a band-like core;
- a mixture layer that is formed on each surface of the core;
- and
- an exposed part that is provided so as to be in contact with one end in a short direction of the core and in which the core is exposed, wherein
- the exposed part is provided at a position where both surfaces of the core face each other, and is adjacent to the mixture layer in the short direction and a longitudinal direction of the core,
- in any one surface of the core, a lead is connected to the exposed part to extend from the one end, and
- on any one surface of the core, an identification mark part capable of specifying a manufacturing process history records is formed on the exposed part.
