In this work an investigation about the use of the solvents 1,1,2,2‐tetramethoxyethane, also called tetramethoxy glyoxal (TMG), and 1,1,2,2‐tetraethoxyethane [also called tetraethoxy glyoxal (TEG)], which belong to the chemical family of carbonyl derivatives, as electrolyte components for electrical double layer capacitors (EDLCs) and lithium‐ion batteries (LIBs) is reported for the first time. TEG and TMG are commercial solvents displaying a good set of properties, a low toxicity, and a low price. Although for EDLCs the use of these solvents does appear particularly appealing, their use in LIBs is certainly interesting. The preliminary results reported in this study indicate that the performance of lithium iron phosphate electrodes in LIBs using electrolytes based on TEG and TMG is promising in terms of capacity, capacity retention at high C rates, and cycling stability.

乙二醛为基础的电化学储能溶剂

在这项工作中，对使用溶剂1,1,2,2-四甲氧基乙烷（也称为四甲氧基乙二醛（TMG））和1,1,2,2-四乙氧基乙烷[也称为四乙氧基乙二醛（TEG）]的使用进行了研究。属于羰基衍生物的化学家族，这是首次报道了双电层电容器（EDLC）和锂离子电池（LIB）的电解质成分。TEG和TMG是商业溶剂，具有良好的性能，低毒性和低价格。尽管对于EDLC来说，使用这些溶剂确实特别吸引人，但它们在LIB中的使用无疑是很有趣的。这项研究报告的初步结果表明，使用基于TEG和TMG的电解质的锂离子电池中磷酸锂铁电极的性能在容量方面是有前途的，
