With the urgent global need for sustainable energy solutions, the development of affordable, eco-friendly batteries is critical. In India, where key materials for lithium-ion (Li-ion) batteries, such as lithium and cobalt, are scarce and require foreign sources, sodium-ion (Na-ion) batteries offer a promising alternative. Amartya Mukhopadhyay, PhD is working to advance Na-ion battery technologies through recent breakthroughs in materials science. His battery prototype is approximately 30% cheaper than Li-ion batteries, operates in a broader temperature range, and is safer to store by creating air- and water-stable sodium-transition metal oxide cathodes and alloy-based anodes. Prof. Mukhopadhyay’s approach also leverages "aqueous processing" of battery electrodes, which replaces toxic solvents with water to reduce production costs and environmental impact.
