Ultrafast organic anodes designed for next-generation rechargeable batteries
Indian researchers developed a covalent organic framework anode that enabled ultra-fast lithium-ion charging and also showed sodium-ion storage potential.
- The two Department of Science and Technology institutes developed a covalent organic framework anode material for rechargeable batteries.
- The material enabled a battery to reach 80% charge in just over one minute while maintaining performance over repeated charging and discharging cycles.
- The material also stored sodium ions, which indicates possible relevance for sodium-ion batteries.
What happened
Researchers from the Indian Association for the Cultivation of Science (IACS) and the S. N. Bose National Centre for Basic Sciences (SNBNCBS), both institutes of the Department of Science and Technology (DST), developed a new porous organic anode material for rechargeable batteries. The material is a covalent organic framework (COF) designed to help lithium ions move more easily inside a battery.
The research team was led by Dr. Urmimala Maitra of IACS and Dr. Pradip Pachfule of SNBNCBS. According to the release, the material enabled a battery to reach 80% charge in just over one minute while maintaining good performance over repeated charging and discharging cycles.
UPSC may ask about covalent organic frameworks, lithium-ion batteries, and the strategic relevance of faster, safer, and lower-cost battery chemistries for electric vehicles and renewable energy integration.
