High Capacity Lithium Ion Battery Cathode and Anode Materials Based on Nano-composites
We recently developed nanocomposite materials for next generation of high capacity, fast charging, long lifetime and low cost lithium ion batteries. These nano-composite materials are:
- Nano Sulfur (n-S) / CNT nanocomposite cathode material
- Nano Silicon (n-Si) / CNT nanocomposite anode material
Compared with lithium cobalt oxide (LiCoO2) and graphite currently used in the lithium ion batteries today, our nanocomposites have following advantages
- Higher energy capacity due to n-S and n-Si active materials
- Faster charging: The small particle size of active materials enhances their reactivity and reaction kinetics. Highly conductive CNT network in the nano-composites ensures fast charge transfer between active material particles and battery current collector.
- Longer lifetime: The small particle size of active materials limits particle volume change and stress, preventing particles from fracture after repeated lithiation / delithiation cycles. The CNT network in our nano-composites reinforces and maintains structural integrity of electrodes during battery operation.
- Our nano-composites have lower cost because they are transition metal (cobalt (Co), nickel (Ni)) free.
