Researchers offer a new mixture of metallic elements to serve as lithium-ion cathodes. This 'high-entropy doping strategy' is part of an effort to remove cobalt -- and expensive and geopolitically ...

The development history, characteristics and applications of high entropy alloys, high entropy oxides and high entropy MXenes are reviewed. High entropy materials as cathode, anode and electrolyte to ...

A new cathode material leverages a rock-salt structure for enhanced magnesium diffusion at a lower temperature. The high-entropy strategy employed creates a crystal structure abundant in stable cation ...

Solid electrolytes with high lithium-ion conductivity can be designed for millimeter-thick battery electrodes by increasing the complexity of their composite superionic crystals, report researchers ...

Current lithium-ion batteries rely on scarce and expensive elements like cobalt and nickel, creating sustainability and supply chain challenges. A new study from Northwestern Engineering’s Chris ...

The term “high entropy” refers to the fact that these alloys contain five or more elements in roughly equal amounts, resulting in a complex microstructure and high configurational entropy. This high ...
