Claims
- 1. An electrode for a battery comprising:
- a sheet of porous metal substrate having three-dimensional communicating spaces defined by a first principal face and a second principal face, most of said three-dimensional communicating spaces being filled with an active material supplied from said first principal face side and subsequently being pressed to reduce the thickness of said sheet,
- wherein said substrate has a layer filled with said active material and occupying most of the thickness of the electrode, and
- a layer of current collector connected to said second principal face and composed of a metallic foil which is not filled with active material and has reduced porosity.
- 2. The electrode for a battery in accordance with claim 1, wherein said layer filled with said active material occupies about 95% to about 99% of the entire thickness of the electrode and said layer of current collector occupies remaining about 5% to about 1%.
- 3. The electrode for a battery in accordance with claim 1, wherein said layer of current collector is formed from a portion of said porous substrate which is not penetrated by the active material supplied from said first principal face side.
- 4. An electrode for a battery comprising:
- a sheet of porous metal substrate having three-dimensional communicating spaces defined by a first principal face and a second principal face,
- wherein said substrate has a layer filled with an active material connected to said first principal face and occupying about 95% to about 99% of the entire thickness of said electrode, and
- a layer of current collector connected to said second principal face and formned into a foil with a porosity of about 5% to about 1% from a part of said pressed porous substrate.
- 5. An electrode for a battery comprising:
- a sheet of compressed porous metal substrate having three-dimensional communicating spaces defined by a first principal face and a second principal face, said three-dimensional communicating spaces being filled with an active material, and
- a thin layer of current collector on said second principal face and composed of a metallic foil which is free of active material and has reduced porosity.
- 6. The electrode for a battery in accordance with claim 5, wherein said layer filled with said active material occupies about 95% to about 99% of the entire thickness of the electrode and said layer of current collector occupies the remaining about 5% to about 1%.
- 7. The electrode for a battery in accordance with claim 5, wherein said layer of current collector is a layer of compressed porous substrate that is free of active material.
