摘要：
Cobalt-free La( Ni, Sn)(5+x) alloys have been identified as low-cost, corrosion-resistant electrodes for nickel-metal-hydride batteries. The structures of these alloys are similar to nonstoichiometric La(Ni,Cu)(5+x) compounds; i.e., they retain the P6/mmm space group while Ni dumbbells occupy La sites. Electrodes fabricated from certain of these novel alloys have storage capacities and cycle lives equivalent to those made from commercial battery-grade AB(5) alloys.
