A rechargeable electrochemical cell with an electrolyte and anode has a cathode including an active cathode material with a surface at which at least one side reaction occurs during a normal discharge cycle of the cell. The outer surface of the cathode material includes a protective coating that inhibits the side reactions without preventing discharge of the cathode.

Electrochemical cell

Disclosed is an electrochemical cell that includes an anode, a cathode, and an electrolyte, the cathode containing more than a trace amount of a sulfur impurity capable of causing the cell to self-discharge and also containing a scavenger that reacts with the impurity to reduce the rate of self-discharge of the cell.

Metal/gas battery featuring a sealed pressure vessel containing a plurality of electrode stacks encased in hydrophobic cups having a gap between them.

Metal/gas battery

Storage battery with multi-cell arrays comprising in each cell a positive nickel electrode (cathode) spaced from a hydrogen containing negative electrode (anode) and alkaline electrolyte medium extending between the electrodes and further comprising a reservoir outside the space defined between electrodes to provide buffer storage of electrolyte displaced by gases generated in the course of cell operation, particularly during overcharging, one or more hydrophobic, microporous membranes to prevent electrolyte loss by entrainment in such evolved gases, and an arrangement of cell construction to provide recombination of free oxygen with hydrogen under safe conditions.
