Dialkylcarbonates are viewed as low-cost, low-toxicity reagents, finding application in many areas of green chemistry. Homogeneous alkoxycarbonylation of cellulose was accomplished by applying dialkycarbonates (dimethyl and diethyl carbonate) in the ionic liquid-electrolyte trioctylphosphonium acetate ([P8881 ][OAc])/DMSO or 1-ethyl-3-methylimidazolium acetate ([emim][OAc]).

High-Energy Lithium-Ion Batteries via a Couette–Taylor-Flow-Reactor

Dr. Schmuch, Dr. Siozios, Professor Dr. Winter, and Dr. Placke review the challenges and opportunities of nickelrich layered oxide cathode materials. They discuss production processes for the layered oxide cathode materials as well as their chemistry and morphology.

Complex Hydrides: A New Category of Solid-state Lithium Fast-ion Conductors

Research and development of solid-state lithium fast-ion conductors is crucial because they can be potentially used as solid electrolytes in all-solid-state batteries, which may solve the safety and energy-density related issues of conventional lithium-ion batteries that use liquid (farmable organic) electrolytes.
