Context: Indian scientists at JNCASR, Bengaluru, have developed a super-fast charging sodium-ion battery that can reach 80% charge in just 6 minutes and last over 3,000 cycles, potentially revolutionising India’s energy storage sector.
About Super-Fast Charging Sodium-Ion Battery:
• What it is: A next-generation sodium-ion battery (SIB) designed to charge ultra-fast and offer extended durability, using indigenous materials and nanotech-based design.
• A next-generation sodium-ion battery (SIB) designed to charge ultra-fast and offer extended durability, using indigenous materials and nanotech-based design.
• Developed by: Jawaharlal Nehru Centre for Advanced Scientific Research (JNCASR), an autonomous institute under the Department of Science and Technology (DST), Govt of India.
• How It Works?
• NASICON-type Material: Provides a stable crystal framework for fast sodium-ion movement in both cathode and anode. Anode Composition (Na₁.₀V₀.₂₅Al₀.₂₅Nb₁.₅(PO₄)₃): This specially engineered compound enhances energy storage and improves ion conductivity. Nanoscale Particle Engineering: Reducing particle size increases surface area, allowing sodium ions to travel faster during charge and discharge. Carbon Coating: A thin carbon layer on particles boosts electrical conductivity and protects from degradation. Aluminium Doping: Adding small amounts of aluminium improves structural integrity and helps maintain battery performance over time.
