1. A secondary battery comprising:

  • positive and negative electrode members arranged on a substantially identical plane, the positive and negative electrode members each having main surfaces and end faces, end faces of the positive and negative electrode members being spaced apart and opposing each other at distance;

    a substrate fixedly contacting a main surface of the positive and negative electrode members and fixedly supporting the positive and negative electrode members;

    a cover member defining, with the substrate, a sealed chamber enclosing and covering the positive and negative electrode members; and

    an electrolyte sealed in the sealed chamber, and the cover member being arranged relative to the electrode members such that the electrolyte is substantially present between the opposite end faces of the positive and negative electrode members, the electrolyte being associated with a battery reaction with the positive and negative electrode members, and wherein the electrolyte is present between the end faces of the positive and negative electrode members in an amount sufficient that the battery reaction substantially takes place at battery reaction sites defined between the opposite end faces of the positive and negative electrode members, said battery reaction sites extending substantially perpendicular to the direction of thickness of the positive and negative electrode members.
