Abstract
A rechargeable lithium battery cell comprises an electrode member comprising a nano-particle transition metal, Co, Cu, Fe, Ni, or Mn having particle size less than about 200 nanometres, which participates with lithium from a complementary electrode source and dissociated electrolyte anions in a reversible redox reaction providing substantial battery cell capacities which improve with continued operation of the cell.
Claims5
A rechargeable Li battery cell comprising a pair of electrode members of complementary polarity, and a separator member interposed therebetween providing an electrolyte
- characterized in that
- one of said electrode members provides a source of Li+ ions and the complementary electrode member comprises an active component consisting essentially of nano-particle transition metal having a particle size range below about 200 nanometres.
