Abstract
Provided is a novel technique related to electrochemical devices that can cause an electrochemical device to display excellent rate characteristics and high-temperature storage characteristics. The electrochemical device is produced using a dispersant composition for an electrochemical device that contains a polymer A. This polymer A includes a nitrile group-containing monomer unit and has an intrinsic viscosity of not less than 0.15 dL/g and less than 1.20 dL/g when dissolved in N-methyl-2-pyrrolidone and measured at a temperature of 25° C.
