Like the mythical beast, HYDRA takes a multi-headed approach to develop the next-generation of high-energy and low-cost Li-ion batteries. HYDRA is short for HYbriD power-energy electRodes for next generation lithium-ion bAtteries. It is an international battery research and innovation project funded by the European Commission’s Horizon 2020 program. The project brings together leading industry and research partners to develop the next generation of lithium-ion batteries and support the growing European battery industry. Through the development of sustainable and high-performance Li-ion cells, HYDRA will contribute to the future of electric mobility and help support the Green Transition. The HYDRA project aims at making improvements in four areas: sustainability, materials, manufacturing and commercialization.
