Metal hydride electrodes based on solid solution type alloy TiV3Nix (0 ≦ x ≦ 0.75)
摘要:
Microstructures, pressure-composition isotherms, and charge-discharge characteristics of TiV2Nix (0 less than or equal to x less than or equal to 0.75) alloys were investigated. The alloys for x greater than or equal to 0.25 composed of a vanadium rich (beta Ti, V) main phase and a TiNi based b.c.c. secondary phase. The secondary phase formed a three dimensional network, enhancing electrode kinetics of the alloys. The maximum discharge capacity was 420 A h kg(-1) for x = 0.56.
