Epsilon Advanced Materials Launches Hard Carbon Anode for Sodium-Ion Battery Storage

Epsilon Advanced Materials announced the launch of an internally developed hard carbon anode material for sodium-ion batteries on May 18, 2026. The newly introduced material is intended for grid-scale energy storage applications as sodium-ion battery technology continues gaining momentum globally due to its lower environmental impact and the wide availability of raw materials compared to lithium-ion chemistries. Major global battery manufacturers, including CATL, along with several domestic cell producers, are actively increasing sodium-ion production capacity to address rising energy storage requirements across utility-scale applications.

The hard carbon anode material has been developed using an agricultural waste-based manufacturing process that utilizes coconut shell byproducts. Through controlled pyrolysis and high-temperature carbonization, the company has created a sustainable alternative that completely removes dependence on graphite-based raw materials. According to the company, the process also requires significantly lower operating temperatures, helping reduce carbon dioxide emissions by up to 50 percent compared to conventional anode manufacturing methods. The material has been engineered to deliver high reversibility, fast charge-discharge performance, and extended operational cycle life required for large-scale stationary energy storage systems.

Key Features of Epsilon’s Hard Carbon Anode Material

Vikram Handa, Managing Director of Epsilon Group, stated that sodium-ion battery chemistry presents a practical solution for long-duration energy storage while utilizing raw materials that are abundantly available within India. The company has already commissioned a graphite anode customer qualification facility in Bellary, Karnataka, supporting its broader battery material expansion strategy. Production targets have been set at 30,000 tons annually by 2028, with plans to scale total capacity to 100,000 tons per annum by 2031 as sodium-ion battery demand continues increasing across global energy storage markets.
