Epsilon Launches Hard Carbon Anode for Sodium-Ion Batteries

Epsilon Advanced Materials Private Limited has announced the launch of its in-house developed hard carbon anode material, specifically designed for sodium-ion batteries, targeting grid-scale energy storage applications. The company said the technology has been developed at a time when sodium-ion chemistry is gaining traction due to its lower cost and abundant raw material availability.

The sustainable anode is produced using agricultural waste such as coconut shells through a controlled processing method that eliminates dependence on graphite. The low-temperature production process also helps reduce carbon emissions by nearly 50% compared to conventional anode manufacturing methods.

The material offers high reversibility, fast charge-discharge capability, and long cycle life, making it suitable for large-scale energy storage systems.

Vikram Handa said sodium-ion technology represents a viable long-term energy storage solution for countries like India, as it leverages widely available domestic raw materials. The company has already set up a graphite anode facility in Bellary, Karnataka, with plans to scale capacity to 30,000 tonnes per annum by 2028 and 100,000 tonnes per annum by 2031.
