Boosting Battery Performance with Seeds and Pitch

Scientists have discovered a novel method to enhance battery performance using Indian trumpetflower seeds and a unique coating.

Key Discoveries

• Hard Carbon from Seeds: Researchers utilized Indian trumpetflower seeds to produce hard carbon, an effective material for storing sodium in sodium-ion batteries.

• Challenges with Hard Carbon:
• Poor electrical conductivity
• Rapid degradation

Solution: Pitch Coating

To overcome these issues, scientists applied a sticky pitch coating containing oxygen, which:

• Improves Energy Storage: The battery retains 77% capacity after 900 cycles, a significant improvement over previous designs.
• Protects Against Electrolyte Damage: The coating shields the carbon from the battery's liquid electrolyte, extending its lifespan.
• Enhances Energy Storage Sites: The oxygen in the coating provides additional storage locations for energy.

Future Implications

This innovative approach could make sodium-ion batteries more efficient and affordable, paving the way for broader adoption in the future.
