This technology could revolutionize energy storage by providing a low-cost, sustainable alternative to lithium-ion batteries. Widespread adoption of sodium-ion batteries can facilitate the transition to renewable energy sources.
- Simplified Synthesis: The bio-carbon anode synthesis involves a low-temperature process (500°C) without the need for an inert atmosphere, significantly reducing production costs to approximately $3/Kg compared to $5-15/Kg for hard carbon.
- Cost Reduction: By eliminating expensive additives and surface modification techniques, the overall cost of the sodium-ion battery technology is reduced.
- High Performance: The sodium-ion full cell demonstrates an energy density of 200 Wh/kg at a current density of 100 mA/g, making it a viable alternative for practical applications.
