India develops ultra-fast charging sodium-ion battery as alternative to lithium technology
This sodium-based innovation could play a key role in democratising access to clean energy
Indian scientists have unveiled a major advancement in battery technology with the development of an ultra-fast charging sodium-ion battery, potentially transforming the country’s energy storage landscape. This is reported by IANS, a partner of TV BRICS.
The innovation offers a cost-effective and scalable alternative to conventional lithium-based systems.
Engineered around a NASICON-type cathode and anode structure, the new sodium-ion battery can charge up to 80 per cent in just six minutes and withstand more than 3,000 charge cycles, addressing two critical limitations of current sodium-based technologies – slow charging and limited lifespan.
The new battery's design enhances safety by mitigating the fire risks and degradation often associated with lithium-ion systems, making it a viable option for widespread deployment in electric vehicles, solar energy storage, and rural electrification.
The technology has been validated using advanced electrochemical testing and quantum simulations, confirming its reliability and efficiency. Experts believe that while further development is required before commercialisation, the research is seen as a milestone in India’s push towards energy self-reliance.

Joao Paulo CapobiancoBrazilian Minister of the Environment and Climate Change"The BRICS countries have a very high level of responsibility because they share an important part of the world's biodiversity, landscapes, populations, food production and water resources. So, we have an opportunity to lead by example. We have our development bank, which can demonstrate and develop new ways of financing programmes. We can reduce the risks for private capital to invest in restoration and efforts to combat desertification"
