News: A research team at the Jawaharlal Nehru Centre for Advanced Scientific Research (JNCASR) has developed a super-fast charging sodium-ion battery (SIB).
About Super-Fast Charging Sodium-Ion Batteries (SIBs)
- The battery is based on a NASICON-type cathode and anode material that can charge up to 80% in just six minutes and last over 3000 charge cycles.
- Innovations involved: This new battery uses a clever mix of chemistry and nanotechnology.
- The team engineered a novel material for the anode—Na₁.₀V₀.₂₅Al₀.₂₅Nb₁.₅(PO₄)₃—and optimized it in three critical ways –
- shrinking the particles to nanoscale
- wrapping them in a thin carbon coat
- improving the anode material by adding a small amount of aluminium
- The team engineered a novel material for the anode—Na₁.₀V₀.₂₅Al₀.₂₅Nb₁.₅(PO₄)₃—and optimized it in three critical ways –
- These tweaks made sodium ions move faster and more safely, enabling both speed and durability.
Advantages of Sodium-Ion Batteries (SIBs)
- Sodium is cheap and abundantly available in India, unlike lithium which is scarce and largely imported.
- A battery built on sodium instead of lithium could help the country to become self-reliant in energy storage technology.
