FIELD: electric elements.
SUBSTANCE: invention relates to polytetrafluoroethylene powders, electrode binder, electrode mixtures, electrodes and secondary storage batteries. Polytetrafluoroethylene powder is intended for use as electrode binder, where water content is 0.010 wt.% or less and the amount of the fluorine-containing compound having a molecular weight of 1000 or less is 25 wt.pts. per billion or less.
EFFECT: reduction or prevention of gas release inside the battery element and deterioration of the battery characteristics.
