Abstract

A new synthetic method has been developed and demonstrated for the utilization of commercially cheap MnO₂ for the production of nanoparticles of LiMn₂O₄ spinel as a cathode material for Li-ion batteries. The process involves the insertion of lithium into electrolytic manganese dioxide (EMD) in an aqueous medium with glucose as a mild reductant in open air. The material resulting from calcination is pure, spinel-structured Li_0.96Mn₂O₄ particles of sub-micrometric and nanometric size that exhibit promising electrochemical behavior in nonaqueous Li-salt solutions. Further development of this process may be interesting for the commercial production of LiMn₂O ₄ for Li-ion batteries.
