Evercharge Energy is developing LIB cells based on innovative electrode materials that can deliver improvements in energy density of >30% -compared to LIBs currently used in EV applications.
We are also focused on supporting the development of a domestic supply chain for the LIB materials and are approaching this task by first considering the elimination of graphite from the anodes.
Several different approaches to high-capacity anodes are under development globally. Candidates to replace graphite include lithium (Li) and silicon (Si) – both of which have higher capacities, but also present several challenges (chemical reactivity and dendrite formation of Li and the swelling problem of Si). A composite of a non-graphitic carbon and a low-cost, Si nano-particle powder is an ideal solution to achieving next-generation LIB performance.
Our cells are based on carbon-silicon composite anode materials that are synthesized from renewable carbon precursors extracted from agricultural waste products. The silicon components are also produced using a low-cost manufacturing process from abundantly available natural sources.
Based on this approach, the key cost/performance benchmark for our LIB cells is projected to improve by a factor if 2x (this benchmark for current generation EV LIB cells is ~ $0.10/KWh/cycle).
