High cycle life, cobalt free, AB{5} metal hydride electrodes [Revised 11/10/98]

PDF Version Also Available for Download.

Description

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