And the article contained the following:
The relatively narrow electrochem. steady window and low ionic conductivity are two critical challenges for Li+-conducting solid polymer electrolytes (SPE). Here, a family of poly-oxalate(POE) structures were prepared as SPE; among them, POEs composed from diols with an odd number of carbons show higher ionic conductivity than those composed from diols with an even number of carbons, and the POE composed from propanediol (C5-POE) has the highest Li+ conductivity The HOMO (HOMO) electrons of POE were found located on the terminal units. When using trifluoroacetate as the terminating unit (POE-F), not only does the HOMO become more neg., but also the HOMO electrons shift to the middle oxalate units, improving the antioxidative capability. Furthermore, the interfacial compatibility across the Li-metal/POE-F is also improved by the generation of a LiF-based solid-electrolyte-interlayer(SEI). With the trifluoroacetate-terminated C5-POE (C5-POE-F) as the electrolyte and Li+-conducting binder in the cathode, the all-solid-state Li/LiNi0.8Mn0.1Co0.1O2(NMC811) cells showed significantly improved stability than the counterpart with poly-ether, providing a promising candidate for the forthcoming all-solid-state high-voltage Li-metal batteries. The experimental process involved the reaction of Pentane-1,5-diol(cas: 111-29-5).Category: alcohols-buliding-blocks
