New class of high entropy materials for energy storage applications

Green Car Congress

A team led by researchers from the Karlsruhe Institute of Technology (KIT) in Germany is proposing a new class of high entropy materials for energy storage applications. The Li-containing entropy-stabilized oxyfluoride (Li x (Co 0.2 V vs. Li + /Li, enabling its use as a cathode active material.

New strategy for dendrite-free Li-metal batteries based on atomic channels

Green Car Congress

Despite the enticing properties of lithium used as an anode material in energy storage systems—such as the extremely high theoretical capacity of 3860 mA h g -1 —practical application is still hindered by the safety issues resulting from lithium dendrite growth.
