Lithium-ion batteries dominate today’s market, but lithium is scarce. Sodium-ion batteries are a promising alternative due to the abundance of sodium, yet current anode materials like graphite underperform with sodium ions. There is a need for cost-effective, high-performance, and environmentally sustainable anode materials.
This invention introduces a method for synthesizing bio-derived carbon from Tamarindus Indica seeds and its composite with sodium titanates (NTO) for use as anodes in sodium-ion batteries (SIBs). The process involves a cost-effective, scalable approach that leverages sustainable sources to produce high-performance anode materials, thereby enhancing the efficiency and reducing the cost of SIBs.
- Utilizes Tamarindus Indica seeds as a bio-derived source for carbon
- Heats powdered seeds at controlled temperatures to produce bio-carbon
- Combines bio-derived carbon with sodium titanates (NTO) to form a composite
- Demonstrates excellent cyclic stability and specific capacity in sodium-ion battery prototypes
- Cost-effective, environmentally friendly, and scalable synthesis process
- Utilizes abundant and renewable bio-materials Improved electrochemical performance over traditional graphite anodes
- Enhances the practicality and affordability of sodium-ion batteries
Sodium-ion batteries using bio-derived carbon and NTO-BC composite anodes show high specific capacity (350 mAh/g for bio-derived carbon and 275 mAh/g for NTO-BC) and good cycle stability.
