India's Epsilon Advanced Materials (EAMPL) has introduced a hard carbon anode material specifically for sodium-ion batteries. This material uses coconut shell waste as a precursor, removing the need for graphite and reducing CO2 emissions by up to 50 percent during production. Targeted at grid-scale energy storage systems, this sodium-ion chemistry offers a more sustainable and cost-effective alternative to lithium-ion batteries. By utilizing abundant agricultural waste, the technology aims to improve supply chain resilience for large-scale battery deployment.
