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.

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.)

Researchers find tin nanoparticles promising electrode material for sodium-ion batteries

Green Car Congress

Tin (Sn) shows promise as a robust electrode material for rechargeable sodium-ion (Na-ion) batteries, according to a new study by a team from the University of Pittsburgh and Sandia National Laboratory. Rechargeable Na-ion batteries work on the same basic principle as Li-ion batteries—i.e., for the positive electrode.

High-capacity GQD-coated VO2 nanoarray electrodes for high-performance Li- and Na-ion batteries

Green Car Congress

Researchers from Nanyang Technical University (NTU) in Singapore have shown high-capacity, high-rate, and durable lithium- and sodium-ion battery (LIB and NIB) performance using single-crystalline long-range-ordered bilayered VO 2 nanoarray electrodes. This is important in boosting the high-rate performance in both Li and Na ion storage.

NETL investigating researching chemistries for large-scale battery- and supercapacitor-based grid energy storage systems

Green Car Congress

The US Department of Energy’s National Energy Technology Laboratory (NETL) is conducting research on alternative options to reduce costs and make large-scale energy storage safer and more practical. Magnesium is much more abundant in the Earth’s crust, making it less expensive than Li by a factor of 24. Earlier post.)
