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

Green Car Congress

Scientists at the US Department of Energy’s Pacific Northwest National Laboratory (PNNL) report new findings about how to make a single-crystal, nickel-rich cathode hardier and more efficient. 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. Haesun Park, Christopher J. 202101698.

Faradion demonstrates proof-of-concept sodium-ion electric bike

Green Car Congress

British battery R&D company Faradion has demonstrated a proof-of-concept electric bike powered by sodium-ion batteries at the headquarters of Williams Advanced Engineering, which collaborated in the development of the bike. Sodium-ion intercalation batteries—i.e., Oxford University was also a partner. Earlier post.)

ANL team develops new class of Li- and Na- rechargeable batteries based on selenium and selenium-sulfur; greater volumetric energy densities than sulfur-based batteries

Green Car Congress

Cycling performance of Li/SeS 2 ?C, Researchers at Argonne National Laboratory have developed selenium and selenium–sulfur (Se x S y )-based cathode materials for a new class of room-temperature lithium and sodium batteries. Unlike the widely studied Li/S system, both Se and Se x S y can be cycled to high voltages (up to 4.6

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

Green Car Congress

The new process is safer and uses less energy than their previous method ( earlier post ) in restoring cathodes to their original capacity and cycle performance. Zheng Chen, a professor of nanoengineering who is affiliated with the Sustainable Power and Energy Center at UC San Diego, led the project. Energy Mater. O 2 (0 Adv.
