摘要:
Described are electrolyte compositions and electrochemical devices containing the electrolyte compositions. The compositions include an organosilicon compound, an imide salt and optionally LiPF6. The electrolytes provide improved high-temperature performance and stability and will operate at temperatures as high as 250° C.
摘要:
Described are compounds of the structure R4—a—Si—(Sp-Y)a—Zb, wherein “a” is integer from 1 to 4; “b” is an integer from 0 to (3×a); “Z,” which is absent when “b”“R” or formula (II), wherein each “R” is halogen, C1-6 linear or branched alkyl, alkenyl, or alkynyl or C1-6 linear or branched halo-alkyl, halo-alkenyl, or halo-alkynyl; each “Sp” C1-15 linear or branched alkylenyl or CMS linear or branched halo-alkylenyl; and each “Y” an organic polar group. Also described are electrolyte compositions containing one or more of these compounds.
摘要:
Described herein are liquid, organosilicon compounds that including a substituent that is a cyano (—CN), cyanate (—OCN), isocyanate (—NCO), thiocyanate (—SCN) or isothiocyanate (—NCS). The organosilicon compounds are useful in electrolyte compositions and can be used in any electrochemical device where electrolytes are conventionally used.
