Abstract
This innovation is concerned with the fabrication of a novel morphology of LiMnO2 to be implemented in revolutionary composite cathode for lithium ion rechargeable batteries. The proposed cathode material and novel fabrication process will overcome capacity fading problems inherent in LiMnO4, exhibit greater utilization of its theoretical capacity, show exceptional cycleability and provide a vehicle for easy scale-up to commercial production. LiMnO2 cathode materials produced by this route are projected to compete very well with the benchmark LiCoO2 system by showing specific capacities in excess of 150 Ah/kg and energy densities greater than 550 Wh/kg while costing substantially less. A cathode of this nature will enable manufacturers to provide NASA with a high energy density, high cycle capacity, low cost alternative to the current state-of the-art LiCoO2 based batteries. Further, batteries based on nanoparticulate LiMnO2 are projected to compete very well in the consumer battery market by providing a safe, cost effective alternative to the environmentally unsound, expensive cobalt based systems.
