Researchers show that layered calcium transition metal oxides can be promising cathode materials for Ca-ion batteries

Green Car Congress

Out of several candidates that could replace Li in rechargeable batteries, calcium (Ca) stands out as a promising metal. Not only is Ca 10,000 times more abundant than Li, but it can also yield—in theory—similar battery performance. Haesun Park, Chung-Ang University, co-corresponding author. —Prof.

UCSD researchers improve method to recycle and renew used cathodes from Li-ion batteries via eutectic molten salts

Green Car Congress

Researchers at the University of California San Diego have improved their recycling process that regenerates degraded cathodes from spent lithium-ion batteries. The team is tuning this process so that it can be used to recycle any type of cathode materials used in lithium-ion and sodium-ion batteries. 2019) “Ambient?Pressure

Researchers find tin nanoparticles promising electrode material for sodium-ion batteries

Green Car Congress

Tin (Sn) shows promise as a robust electrode material for rechargeable sodium-ion (Na-ion) batteries, according to a new study by a team from the University of Pittsburgh and Sandia National Laboratory. Rechargeable Na-ion batteries work on the same basic principle as Li-ion batteries—i.e., for the positive electrode.
