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]).

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.

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.

Solid oxide fuel cells (SOFC) and solid oxide electrolyzers (SOE) are in the early stages of development; however, the performance that has been achieved shows promise for conversion between chemical and electrical energy.

固体氧化物燃料电池(SOFC)和固体氧化物电解池(SOE)正处于早期开发阶段,但性能发展已有望实现电化学能量的转化。
