Tohoku team develops new electrolyte to support rechargeable calcium batteries

Green Car Congress

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. High-energy-density and low-cost calcium (Ca) batteries have been proposed as ‘beyond-Li-ion’ electrochemical energy storage devices.

Researchers use graphite positive electrodes in high-capacity rechargeable lithium/chlorine batteries

Green Car Congress

This work could open up widely available, low-cost graphitic materials for high-capacity alkali metal/Cl 2 batteries. The new study found that the evolution of graphite over battery cycling, including intercalation/deintercalation and exfoliation, generated sufficient pores for hosting LiCl/Cl 2 redox. 2c07826.

Roskill sees recovery in lithium industry, buoyed by demand from rechargeable battery applications

Green Car Congress

In 2019, rechargeable batteries accounted for 54% of total lithium demand, almost entirely from Li-ion battery technologies. Prices continued to slide in Q3 2020, with China spot prices falling below US$5,000/t CIF (Cost, Insurance, and Freight) for battery-grade lithium carbonate; contract prices edged closer to US$10,000/t CIF.

New liquid-sulfur/sulfide composite cathodes for high-rate magnesium rechargeable batteries

Green Car Congress

Magnesium rechargeable batteries (MRBs), in which high-capacity Mg metal is used as the anode material, are promising candidates for next-generation batteries due to their energy density, safety, and cost. However, the lack of high-performance cathode materials impedes their development. ©Kohei Shimokawa.
