alternative to lithium-ion batteries tagged posts

Findings could pave the way for a cost-efficient, high-performing calcium-ion battery. Concerns regarding scarcity, high prices, and safety regarding the long-term use of lithium-ion batteries has prompted a team of researchers from Rensselaer Polytechnic Institute to propose a greener, more efficient, and less expensive energy storage alternative.

In research published recently in Proceedings of the National Academy of Sciences (PNAS), corresponding author Nikhil Koratkar, the John A. Clark and Edward T. Crossan Professor of Engineering at Rensselaer, and his team, assert that calcium ions could be used as an alternative to lithium-ions in batteries because of its abundance and low cost.

New cathode, electrolyte allow high-power battery previously considered impossible. Magnesium batteries have long been considered a potentially safer and less expensive alternative to lithium-ion batteries, but previous versions have been severely limited in the power they delivered.

Researchers from the University of Houston and the Toyota Research Institute of North America (TRINA) report in Nature Energy that they have developed a new cathode and electrolyte — previously the limiting factors for a high-energy magnesium battery — to ...
