Epsilon Advanced Materials from India and South Korea’s Daejoo Electronic Materials have formed a partnership to develop a cutting-edge Silicon-Graphite composite anode for lithium-ion batteries. This collaboration seeks to produce an anode material with a high capacity that can increase the battery’s discharge capacity by more than 50%, potentially revolutionizing the electric vehicle industry. Combining Epsilon’s graphite production know-how with Daejoo’s silicon technology, the companies aim to create a product that surpasses existing anode materials in efficiency and durability.
The newly developed Silicon-Graphite composite anode, known as Gen-1 material, is engineered to reach a specific capacity ranging from 450 to 600 mAh/g. This innovation is set to enhance the longevity and discharge capacity of EV batteries. By merging silicon’s high capacity with graphite’s stability, the goal is to offer a robust solution that satisfies the requirements of electric vehicles and other high-power applications. This partnership represents a pivotal advancement in the quest for superior battery materials, emphasizing the improvement of battery lifespan and efficiency, which are vital for EVs where range and performance are key.
Through the partnership, Epsilon will provide synthetic graphite to develop SiOx-Graphite composites, set to be tested in the laboratories of both Epsilon and Daejoo. The initial development and evaluation phase is anticipated to conclude by the end of 2024. Subsequently, the companies will seek material qualification with leading cell manufacturers. Success in this joint development may result in the widespread implementation of efficient, cost-effective anodes that satisfy the growing energy requirements of contemporary mobility.
