Title: Electrochemical photovoltaic cells and electrodes

Abstract

Improved electrochemical photovoltaic cells and electrodes for use therein, particularly electrodes employing amorphous silicon or polyacetylene coating are produced by a process which includes filling pinholes or porous openings in the coatings by electrochemical oxidation of selected monomers to deposit insulating polymer in the openings.

  • Electrodes are disclosed using essentially insoluble active material are disclosed which can be used in a variety of electrochemical cells and rechargeable accumulators. Plastic materials are used to ensure porosity and strength and to sinter the electrode ingredients and active material together. Details of the essentially insoluble compound active material are disclosed and of an electrolyte recommended for use with the electrodes. Aspects of this invention are applicable particularly to Ni-Cd, Ag-Cd, Ag-Zn, Ni-Fe, Ni-Zn, Metal-Air, fuel or solar cells.

  • Disclosed are transition metal electrodes for electrochemical cells using gel-state and solid-state polymers. The electrodes are suitable for use in primary and secondary cells. The electrodes (either negative electrode or positive electrode) are characterized by uniform dispersion of the transition metal at the nanoscale in the polymer. The transition metal moiety is structurally amorphous, so no capacity fade should occur due to lattice expansion/contraction mechanisms. The small grain size, amorphous structure and homogeneous distribution provide improved charge/discharge cycling performance, and a higher initial discharge rate capability. The cells can be cycled at high current densities, limited only by the electrolytemore » conductivity. A method of making the electrodes (positive and negative), and their usage in electrochemical cells are disclosed.« less
