SOLID ELECTROLYTIC MOLDINGS, ELECTRODE MOLDINGS, AND ELECTROCHEMICAL ELEMENTS

摘要

Disclosed are a molded solid electrolyte and molded electrode having excellent electrochemical properties and high procesability. As a binder for these molded articles, a hydrogenated block copolymer is used which is obtained by hydrogenating a straight chain or branched block copolymer containing a block (A) comprising polybutadiene whose 1,2-vinyl bond content is 15% or less and a block (B) comprising a butadiene (co)polymer consisting of 50 to 100 % by weight of butadiene and 0 to 50 % by weight of other monomers in which 1,2-vinyl bond content of butadiene portion is 20 to 90%, wherein (A) / (B) = 5 to 70 / 95 to 30 % by weight.
