In a breakthrough that could redefine the future of energy storage, researchers at Bengaluru’s Jawaharlal Nehru Centre for Advanced Scientific Research (JNCASR) have developed a high-performance sodium-ion battery (SIB) that charges up to 80% in just six minutes and lasts over 3,000 cycles.
Spearheaded by Prof. Premkumar Senguttuvan and Ph.D. scholar Biplab Patra, the innovation leverages nanotechnology and material engineering to overcome key limitations of traditional SIBs—namely, slow charging and limited lifespan. The team designed a new anode material—Na₁.₀V₀.₂₅Al₀.₂₅Nb₁.₅(PO₄)₃—refined through particle downsizing, carbon coating, and aluminum doping. These enhancements enable faster ion movement, leading to quicker, safer charging and improved durability.
Sodium, being cost-effective and abundantly available in India, presents a strategic alternative to lithium, which is scarce and geopolitically sensitive. This innovation aligns with the government’s Atmanirbhar Bharat mission to foster self-reliance in clean energy technologies.
Rigorous testing, including quantum simulations and electrochemical cycling, has validated the battery’s performance and safety advantages. The potential applications are vast—ranging from electric vehicles and solar grids to rural electrification and drone tech—making clean energy more accessible across the country.
While commercialization may still be a few steps away, this breakthrough positions India as a rising leader in the global green tech revolution.
