Skoltech researchers in collaboration with scientists from the Institute for Problems of Chemical Physics of RAS and the Ural Federal University have shown that high-capacity, high-power batteries can be made from organic materials without lithium or other rare elements. In addition, they demonstrated the impressive stability of cathode materials and recorded high energy density in fast charge/discharge potassium-based batteries. The results of their studies were published in the Journal of Materials Chemistry A, the Journal of Physical Chemistry Letters and Chemical Communications.
Lithium-ion batteries are widely used for energy storage, particularly in portable electronics. The demand for batteries is surging due to the rapid advancement of electric vehicles with high requirements for lithium. For example, Volvo intends to increase the share of electric vehicles to 50 percent of its overall sales by 2025, and Daimler announced its plans to give up internal combustion engines altogether, shifting the emphasis to electric vehicles.
