Abstract
A porous nickel electrode substrate having a central high conductivity core sandwiched between two layers of porous conductive material such as nickel foam or nickel felt. The porous conductive material is plated with nickel and then sintered. By selectively controlling the plating of nickel on the porous material, variable conductivities may be designed into the substrate.
Claims4
A process for varying the conductivity of an electrode substrate, the process comprising:
- 1) providing an electrically conductive core having opposing sides,
- 2) affixing at least one porous layer to each side of the core, the porous layer selected from the group consisting of foam and felt,
- 3) depositing nickel from the decomposition of nickel tetracarbonyl directly onto each porous layer,
- 4) causing the concentration of the nickel deposit from step 3) to vary along the substrate, and
- 5) sintering the nickel deposit.
