Epsilon Advanced Materials Debuts Anode Material for Sodium Ion Batteries

Epsilon Advanced Materials Private Limited announced the launch of an in-house developed hard carbon anode material designed for sodium-ion batteries on May 18, 2026. The newly introduced material specifically targets grid-scale energy storage systems at a time when sodium-ion chemistry is gaining commercial traction due to its lower environmental footprint and material abundance compared to lithium-ion alternatives. Global battery manufacturers, including CATL, alongside several domestic cell producers, are actively expanding sodium-ion production capability to meet energy storage demands.

The sustainable anode utilizes an agricultural byproduct strategy, processing coconut shell waste through controlled pyrolysis and high-temperature carbonization. This bio-based manufacturing method completely eliminates dependence on graphite and requires significantly lower processing temperatures, resulting in up to 50 percent lower carbon dioxide emissions compared to conventional anode production. The material features an engineered microarchitecture that provides high reversibility, fast charge-discharge capability, and an extended cycle life necessary for thousands of operational charge cycles in grid applications.

Vikram Handa, Managing Director of Epsilon Group, stated that sodium-ion represents a viable chemistry for long-term energy storage, leveraging raw materials that are widely available within India. The group has already commissioned a graphite anode customer qualification facility in Bellary, Karnataka, with production targets set for 30,000 tons per annum by 2028 and an eventual scale-up to 100,000 tons per annum by 2031.
