Leclanché reduces cobalt in NMCA cells from 20 to 5%; 20% higher energy density; water-based production

Green Car Congress

Leclanché SA has reduced the cobalt content in NMCA as cathode material from 20% to 5% and manufacture the electrodes using an environmentally friendly water-based process. Leclanché is the first company to implement the environmentally friendly process in the production of Li-ion cells. But, now we have mastered the process.

MIT Sequential Decomposition Synthesis process produces thin solid-state electrolytes without sintering

Green Car Congress

A team from MIT has developed a new approach to fabricating oxide-based solid-state electrolytes that are comparable in thickness to the polymer separators found in current Li-ion batteries without sintering: sequential decomposition synthesis (SDS). Recent progress in solid-state battery (SSB) electrolytes such as Li garnets (e.g.,
