Epsilon Launches Epsil Anode Material

Epsilon Advanced Materials has launched Epsil, a silicon–graphite composite anode material designed to improve electric vehicle (EV) battery energy density, charging performance and driving range. The company projects that the new material could increase EV driving range by up to 30% without requiring a larger battery pack, while also enabling manufacturers to develop smaller battery packs with existing range capabilities. Epsilon Launches “Epsil” Silicon Blend Graphite Anode Material, Targeting 20–30% More EV Range.

Launched on November 4, 2026, in Mumbai, Epsil combines higher anode capacity with fast-charging capabilities and compatibility with existing battery cell manufacturing lines. The material has a reversible capacity of 600–650 mAh/g, compared with 340–360 mAh/g for conventional graphite anodes, offering battery manufacturers an opportunity to improve cell-level energy density.

The silicon-blended graphite material has been developed to address cycle-life challenges associated with silicon expansion during charging and contraction during discharging. Epsilon said its material is designed to support charging rates of 1C to 5C while controlling expansion and maintaining uniform silicon dispersion within the anode.

Epsil also incorporates design measures intended to reduce lithium plating risks during high-rate charging and the associated possibility of dendrite formation. However, actual performance will depend on cell design, operating temperature, charging protocols and validation by individual battery manufacturers.

Vikram Handa, Managing Director of Epsilon Advanced Materials, said the material aims to help battery manufacturers achieve greater driving range and faster charging without increasing battery pack dimensions. He highlighted its higher anode capacity, fast-charging capabilities and compatibility with existing manufacturing infrastructure, alongside the opportunity to establish a reliable anode material supply from India.

The launch comes amid growing global demand for EV batteries. According to the International Energy Agency (IEA), more than 20 million electric cars were sold worldwide in 2025, while EV battery deployment reached 1.2 TWh. The agency expects annual deployment to approach 3 TWh by 2030.

Epsilon Advanced Materials Expands Battery Material Manufacturing

Epsilon Advanced Materials Pvt. Ltd., established in 2018, develops sustainable and high-performance battery materials, including anode and cathode active materials, to strengthen domestic and global battery supply chains.

The company has commissioned EAM-ONE, India’s first commercial graphite anode material plant, in Vijayanagar, Karnataka. It plans to increase production capacity to 30,000 tonnes annually by 2028, with further expansion to 100,000 tonnes per annum by 2031.

Epsilon has also announced a $650 million investment in North Carolina for a graphite anode material facility with a planned capacity of 60,000 tonnes by 2031. Additionally, the company has entered the lithium iron phosphate (LFP) cathode active material business through a technology centre in Germany.

Epsilon is planning to establish India’s first cathode active material manufacturing facility, targeting 20,000 tonnes of annual capacity by 2028 and scaling up to 100,000 tonnes per annum by 2035. These initiatives are aimed at strengthening its position in the global battery materials industry and supporting the development of domestic manufacturing capabilities.
