摘要： Activated rechargeable hydrogen storage electrodes that are especially suitable for sealed, starved electrochemical cells and methods for making them are provided. The activated electrode includes a body of hydrogen storage active material that is composed of an agglomeration of particles of active hydrogen storage material. The body contains a residual amount of hydrogen and may have a modified surface, the residual amount of hydrogen generally being equivalent to a potential of about -0.7 volts versus a Hg/HgO reference electrode when discharged at a rate of about 5 mA/gram to 25 mA/gram of active material.The method provided for activating a rechargeable hydrogen storage negative electrode includes contacting the electrode with alkaline material for sufficient time at sufficient temperature to alter the surface oxides on the electrode present on the electrodes after fabrication to increase the charge acceptance and electrochemical hydrogen transfer rate and discharging at least a portion of the initial charge present in the electrode. The surface oxides may be treated by several methods, such as by contact with alkaline material or electrochemically.

摘要： Electrochemical and thermal hydrogen storage alloy compositions that provide superior performance, including an electrochemical hydrogen storage alloy that provides superior low temperature discharge characteristics. The alloy compositions include microstructures in the interface region that are highly porous and that include catalytic metallic particles. The microstructures include a large volume fraction of voids having spherical or channel-like shapes and are sufficiently open structurally to facilitate greater mobility of reactive species within the microstructure and in the vicinity of catalytic metallic particles. Greater accessibility to reactive sites accordingly results. The greater mobility of reactive species and/or the greater density of catalytic particles lead to faster kinetics and improved performance (e.g. higher power), especially at low operating temperatures. The microstructures may be formed through inclusion of a microstructure tuning element in the alloy composition, through control of processing conditions and/or through inclusion of etching steps in the post-formation processing of hydrogen storage alloys.
