NOVEL TRANSITION METAL OXIDE ANODE FOR HIGH RATE LITHIUM ION BATTERY

Military operating in remote locations have increasing demand for man-portable electric power for communications and other advanced electronic devices, which is currently met by Li/SO2 (BA-5590) or Li/MnO2 (BA-2590) primary batteries. In order to substantially reduce the logistic burden and the cost for power, this is a growing trend calling for the replacement of primary power source to rechargeable ones. However, there are still a number of obstacles for the soldiers in the field to adopt the rechargeable lithium ion battery as the preferred power sources; one of which is because of its slow recharge rate. Driven by the strong market pull for this technology, Enogetek has invented a unique approach to address the issues related to the conventional non-carbonaceous negative electrodes for lithium ion battery. The lithium ion battery containing such nanostructured transition metal oxide anode promises great advantages, including 1) high energy density (>200 Wh/kg); 2) high rate capability (>4 C charge and discharge rate);3) Excellent cycleability (>100 cycles with 100% DOD); 4) Minimum initial capacity loss; 5) good scalability and 6) wide operation temperature range (-40oC- 70oC). Therefore, it can meet the stringent demand as set in this solicitation.
