Abstract
Thermoplastic elastomers such as styrene‐butadiene‐styrene block copolymer (SBS) and styrene‐ethylene/butylene‐styrene block copolymer (SEBS) were used successfully as binding materials for metal hydride (MH) electrodes of a nickel‐metal hydride battery. These binding materials have a rubber‐like nature and are soluble in organic solvents. It was easy to remove the alloy powder from a used electrode for recycling. The battery performance depended on both the kind and amount of binding materials. The best discharge capacity and rate capability were obtained for MH electrodes containing 2–5 weight percent (w/o) SEBS. The particle size distributions for the alloy were examined successfully.
