    摘要： The present invention relates to a solid electrolyte composition comprising:



    a) at least one (per)fuoropolyether comprising a (per)fluoropolyoxyalkylene chain [chain (Rpf)] having two chain ends, wherein at least one chain end has formula (I):

    —[CH(J)CH2O]na[CH2CH(J)O]na′—H  (I)

    wherein each J is independently H, aryl, straight or branched alkyl, and na and na′, equal to or different from each other, are zero or an integer from 1 to 50, with the proviso that na+na′ is from 1 to 50;
    b) a poly(alkylene oxide) comprising chains of formula (II):

    R1B—[OCHR1A(CH2)jCHR2A]n—OR2B  (II)

    wherein each of R1A and R2A is independently a hydrogen atom or a C1-C5 alkyl group, j is zero or an integer of 1 to 2, R1B and R2B is independently a hydrogen atom or a C1-C3 alkyl group, and n is an integer from 5 to 1000, and
    c) at least one lithium salt.
