Abstract
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.
