Mumbai, May 18 -- Epsilon Advanced Materials (EAMPL) has developed a hard carbon anode material designed for sodium-ion batteries used in grid-scale Energy Storage Systems (ESS). Developed through internal research and development, the graphite-free material provides an alternative for cell manufacturers as sodium-ion chemistry gains adoption due to the abundance of sodium and its lower environmental footprint compared to lithium extraction.

The material utilises coconut shell waste as its primary carbon precursor. Through pyrolysis and high-temperature carbonisation, this agricultural byproduct is converted into a disordered carbon structure with the interlayer spacing and nanopore architecture required for sodium-ion storage.
