| Abstract Scope |
This study aims to increase surface area and the number of intercalation sites for lithium ions using the carbon nanostructures (CNTs & GNPs), which in-turns will enhance the electrochemical performance of the cathode material (LMO).Carbon nanostructures (CNTs & GNPs) boost the rate capabilities and cyclic performance of lithium transition metal oxides. The specific capacity at 1 C-rate was 126.4 mAh/g and maintained at 118 mAh/g at 5C rate. Moreover, capacity retention was 90% after 100 cycles. Energy storage systems pose a significant safety concern at a higher temperature and are limited to 30% to 50 % of their potential for safety reasons. The energy storage system from the proposed composites will allow the usage above 50% of the potential, even at higher temperature and discharge rates. The energy storage systems from the composites will resist incendiary and capacity deteriorating reactions. |
