摘要

Problem to be solved: to provide a new technique of electrochemical elements capable of exhibiting excellent rate characteristics and high temperature storage characteristics in electrochemical devices.In the manufacture of an electrochemical device, a dispersant composition for an electrochemical device containing polymer A is used. Here, the polymer a contains a nitrile group containing monomer unit, and the polymer A is dissolved in N-methyl-2-pyrrolidone and the intrinsic viscosity measured at 25 ° C. is less than 0.15 DL / g or greater than 1.20 DL / G.No selection
