UH, Toyota researchers develop new cathode and electrolyte for high-power Mg battery rivaling Li-ion

Green Car Congress

Magnesium batteries have long been considered a potentially safer and less expensive alternative to lithium-ion batteries, but previous versions have been severely limited in the power they delivered. Magnesium ions hold twice the charge of lithium, while having a similar ionic radius. —Dong et al. Tutusaus, O.,

Researchers use tailored deep eutectic solvent to extract critical metals from mixed cathode materials

Green Car Congress

Deep eutectic solvents are a new class of ionic liquid (IL) analogues; they are formed from a eutectic mixture of Lewis or Brønsted acids and bases which can contain a variety of anionic and/or cationic species.

Researchers report first direct observation of anionic redox in a lithium-rich battery material

Green Car Congress

Conventional Li-ion batteries work by cationic redox, when a metal ion changes its oxidation state as lithium is inserted or removed. Within this insertion framework, only one lithium-ion can be stored per metal ion. Lithium-rich cathodes, however, can store much more. —Li et al.

APRA-E awards WUSTL $2M to develop predictive battery management system for plug-in vehicles; targeting more efficient use

Green Car Congress

Louis (WUSTL) will receive $2 million from the US Department of Energy’s ARPA-E to design a predictive battery management system for lithium-ion batteries to guarantee their longevity, safety and performance. If Li-ion batteries are charged too quickly, they can heat up and may explode. —Venkat Subramanian.
