Scientists from Tohoku University have developed a new fluorine-free calcium (Ca) electrolyte based on a hydrogen (monocarborane) cluster that could potentially realize rechargeable Ca batteries.
The researchers say the new material, achieved by designing the coordination structure of Ca cation with a weakly coordinating anion and mixed solvents, shows markedly improved electrochemical performances such as high conductivity and high electrochemical stabilities.
Current lithium-ion (Li-ion) batteries have some drawbacks. They are approaching their demand limits of theoretical energy density and cost, and lithium is not naturally plentiful. [Read more…] about New material enables the usage of ‘calcium’ for batteries
