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.

BNL-led team finds electrolyte additive enables stable high-voltage cycling of nickel-rich layered cathodes

Green Car Congress

This research was conducted as part of the DOE-sponsored Battery500 Consortium, which is led by DOE’s Pacific Northwest National Laboratory (PNNL) and is working to increase the energy density of lithium batteries for electric vehicles significantly. One of the main issues is particle cracking during high-voltage charge-discharge cycles.
