Li-ion batteries (LIBs) have attracted interest in wide range of commercial applications from small-scale portable electronics to large-scale electric vehicles, and energy grids since its first commercial launch by Sony incorporation in 1991. In the current power-hungry scenario, where the energy demand is constantly rising, the need for better energy storage technology that can offer both high energy and high power is warranted. In general, three components of the batteries determines their final performance: 1) anode; 2) cathode and 3) electrolyte. The current LIBs technology suffer from low-rate performance, sluggish lithium diffusion and poor cycle life due to low electrical conductivity and poor structural stability of the electrode materials. Thus, our group is taking efforts to develop new electrode materials (anode and cathode) with high theoretical capacity and long-term cycling stability as well as non-flammable and safe electrolytes.
- High voltage cathode materials (> 5 V) for high energy batteries
- Carbon and conversion-type anode materials
