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. —Li et al. Lithium-rich cathodes, however, can store much more. Barbiellini, B.
