PNNL: single-crystal nickel-rich cathode holds promise for next-generation Li-ion batteries

Green Car Congress

High-energy nickel (Ni)–rich cathode will play a key role in advanced lithium (Li)–ion batteries, but it suffers from moisture sensitivity, side reactions, and gas generation. We observe reversible planar gliding and microcracking along the (003) plane in a single-crystalline Ni-rich cathode. —Bi et al.

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.

ARPA-E awarding $39M to 16 projects to grow the domestic critical minerals supply chain

Green Car Congress

The University of Texas at Arlington will develop acoustic stimulation and electrolytic proton production to produce lithium (Li) and nickel (Ni) from CO 2 -reactive minerals and rocks that contain calcium (Ca) and magnesium (Mg), while sequestering CO 2 in the form of carbonate solids.

Researchers call for integration of materials sustainability into battery research; the need for in situ monitoring

Green Car Congress

A nearly threefold decrease of the stored kWh price to €200 per kWh at the pack level is predicted in the next 10 years, driven at least in part by both the large volume production and the realistic prospects of a second life for electric vehicle batteries. Note the trend in abundances of Al > Ca > Mg > Na > Li, and Fe > Mn > Ni > Co.

Take a detailed look at 7 types of energy storage batteries

Setec Powerr

Energy storage is storing energy through a medium or device and releasing it when needed. Sodium-sulfur battery: Sodium-sulfur battery is a secondary battery with sodium metal as the negative electrode, sulfur as the positive electrode, and ceramic tube as the electrolyte diaphragm. Classification of energy storage.
