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.

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. Illustration of the process to restore lithium ions to degraded NMC cathodes using eutectic molten salts at ambient pressure. —Zheng Chen.

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. Travertine Technologies. from gangue minerals.

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

Green Car Congress

Although estimates vary widely, the predicted penetration of lithium-ion technology into these large-volume markets could result in as much as a threefold increase of production for the cathode material, reaching nearly 400,000 tonnes per year by 2020. Note the trend in abundances of Al > Ca > Mg > Na > Li, and Fe > Mn > Ni > Co.
