Salient technical features and Advantages of the Technology
  • The Ferric oxide porous nanostructures have a high theoretical capacity of 1007 mAh/g, exceeding the capacity of commonly used graphite anodes. Half-cell testing confirms this advantage, delivering a reversible capacity of 903 mAh/g at a 1C rate. 
  • Full-cell testing, using both the Ferric oxide anode and a LiCoO2 cathode, demonstrates exceptional stability. The cell retains 91% of its capacity after 100 cycles, even at a demanding 1C rate. This translates to a maintained capacity of around 800 mAh/g, highlighting the material's ability to endure repeated charging and discharging cycles with minimal capacity loss. 
  • The porous nanostructure design allows the Ferric oxide anode to deliver excellent rate capability. The material can handle high current densities (5C rate) while maintaining efficient lithium-ion storage. 
  • Ferric oxide is a readily available and cost-effective material compared to some alternatives. Additionally, the potential for using water-based binders in the fabrication process opens doors for further cost reduction and improved safety by eliminating the need for flammable organic solvents.
