Patent ID: 7585586

Claim:
A battery, comprising: a positive electrode substrate, which is a conductor of a low potential; a negative electrode substrate which is a conductor of a high potential; an additive to activate or ionize water in an electrolyte; a film which is porous and located between the positive electrode substrate and the negative electrode substrate to space the positive electrode substrate and the negative electrode substrate at a minimum distance said film being an osmotic membrane coating on the negative electrode substrate; an insulation shell which encases the positive electrode substrate and the negative electrode substrate and has at least one water inlet to add the electrolyte to the film, and keeps the positive electrode substrate and the negative electrode substrate in contact with each other tightly together; and a water absorbing substance located between the positive electrode substrate and the film to store water for moisturizing; wherein ions generated by the ionized water transmit electricity in the battery, the positive electrode substrate and the negative electrode substrate that being spaced from each other at the minimum distance generate a maximum potential to provide electricity of the battery.
