Argonne team develops new approach to cobalt-free Li-ion cathodes

Green Car Congress

Researchers at Argonne National Laboratory have developed a new approach to cobalt-free Li-ion cathodes that avoids some of the problems with other low-cobalt cathode approaches. To make use of the best out of each of these three ions, the industry is now based on LiNi 1-y-z Mn y Co z O 2 with (1-y-z) 0.2). Croy, Brandon R.

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.,
