ADDITIVE FOR ELECTRODE

摘要

An additive for electrodes comprises an aqueous dispersion of a fluorine-containing polymer containing a surfactant. When the upper limit value of the content of fluorine in the polymer molecule structure is 67.0 or less and the lower limit value of that is 45.0 or more, the electrochemical stability especially of the negative electrode is excellent. The additive exhibits a favorable cell initial characteristic and an favorable cell charging/discharging characteristic.
