Hydrogen@ storage alloy anode for sec. cell

摘要

A hydrogen storage alloy anode for a sec. cell has its surface coated with a C substance at 0.05 - 0.5 mg / cm<2>, is produced from an alloy of the AB2 series and is in the form of a plate. Also claimed is a process for producing the above anode, comprising: (a) forming a H storage alloy of the AB2 series by dissolving V, Ti, Zr, Ni, Co and Mn; (b) heat treating the alloy at 900 - 1100 deg C for 4 - 6 hrs.; (c) homogeneously pulverising the alloy; (d) forming an anode plate by coating and pressing the alloy powder onto a substrate; (e) sintering the anode plate; and (f) coating the surface of the anode plate with a carbon substance. The sec. cell contg. the above anode mfd. by the above process is further claimed.
