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.

Lithium-ion batteries are the most common rechargeable battery today, but lithium is a limited resource. Sodium-ion batteries are a promising alternative because sodium is much more abundant, but current anode materials, such as graphite, do not perform adequately with sodium ions. There is a need for low-cost, high-performance anode materials that are also environmentally sustainable.
- This innovation utilizes Tamarindus Indica seeds as a bio-derived source for carbon.
- Powdered seeds are heated at controlled temperatures to produce bio-carbon.
- This technology combines bio-derived carbon with sodium titanates (NTO) to form a composite.
- Sodium-ion battery prototypes demonstrate excellent cyclic stability and specific capacity.
- This methodology is cost-effective, environmentally friendly, and scalable synthesis process.
- It utilizes abundant and renewable bio-materials.
- It shows improved electrochemical performance over traditional graphite anodes.
- It 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.
