For LIB anodes
Carbon/Si materials for LIB anodes
Our LIB anode materials are synthesized by processing the carbon in the presence of nano-silicon, resulting in a C/Si composite. Different ratios of C:Si have been synthesized to address different performance requirements (capacity, cycle-life, etc.). Advantages of our process include the ability to synthesize a very homogeneous composite with stable C/Si interface properties.
The current industry standard graphite-based anode materials offer a capacity of ~372 mAh/g. The next generation of C/Si anode materials are projected to have capacities between 500 mAh/g and 2500 mAh/g, enabling high energy-density and fast charging applications.
For LIB cathodes
Carbon/S materials for LIB cathodes
For next-generation high energy-density batteries, Li-sulfur batteries have great potential. We are using our carbon composite technology to synthesize pre-lithiated carbon/sulfur materials for cathode applications in Li-S batteries. The sulfur component of the C/S composites is uniformly distributed in the carbon matrix – whose hardness and porosity levels can be adjusted via our processing parameters.
Our C/S materials also allow the use of carbon-based anodes – thereby eliminating the need to use expensive lithium-based anodes.
For NIB electrodes
Carbon/S and hard carbon materials for NIB electrodes
Carbon/S and hard carbon materials for NIB cathodes and anodes
For sodium-ion batteries, the same process is used to synthesize pre-sodiated carbon/sulfur cathode materials. Also, since NIBs cannot use graphite anodes, our hard carbon anode materials synthesized using the same platform technology – are suitable for NIB anode applications.
As we use carbon-based materials for both electrodes – we can significantly reduce the cost ($/kWh) of these cells, enabling cost sensitive applications like grid-attached energy storage and the emerging small electric-vehicle market.
For LIC electrodes
Carbon materials for ultrafast dual carbon lithium-ion capacitors
This type of ultra-fast charging LIC requires a high porosity activated carbon for its cathode and a high capacity hard carbon anode. We use our carbon technology process to synthesize advanced carbons for both these electrodes. The hard carbon anode material has a capacity of ~400 mAh/g, with excellent capacity retention even at a C-rate of 100. This type of performance (fast charging capability) is not possible with conventional graphite anode materials.
