    摘要： A low-cost electrochemical capacitor is provided which has high capacity and excellent charging and discharging characteristics, simultaneously has excellent safety and reliability, and has the basic performance as a capacitor, achieved in that, as the electrolyte between a negative electrode and a positive electrode, a solution of an ambient temperature molten salt and a specific polyether copolymer is allowed to gel using a specific photoreaction initiator and is held between the two electrodes. This low-cost electrochemical capacitor has the basic performance of a capacitor, has high capacity and excellent charging and discharging characteristics without use of a separator, and simultaneously has excellent safety and reliability.

    摘要： Provided is a binder for a battery electrode, the binder having superior binding properties and being capable of effectively decreasing the internal resistance of a battery while still being usable as an aqueous binder with low environmental burden. A binder for a battery electrode according to the present invention has a core shell structure of a core section (A) containing a copolymer the principal constituent of which is methyl methacrylate and a shell section (B) having a (meth)acrylate-based copolymer containing (meth)acrylate as a polymerization component, wherein the swelling ratios with respect to a mixed solvent in which ethylene carbonate and diethyl carbonate are mixed at a volume ratio of 3:7 are 10% or less for the resin constituting the core section (A) and 30% or more for the resin constituting the shell section (B).
