Method and device for producing a maintenance-free battery having a fixed electrolyte

Method for producing an accumulator cell having a fixed electrolyte, wherein the electrolyte is introduced in a flowable form into the accumulator cell and wherein the fixing of the electrolyte and the forming of an active mass inside the accumulator cell are effected simultaneously, wherein the electrolyte is introduced into the accumulator cell in the form of a sol mixture, and is then fixed in the accumulator cell in the form of a gel, characterized in that the gel is prepared from at least one sol and one acid, whereby at least a thickener and the acid are mixed only at the time of their introduction into the accumulator cell, whereby simultaneously with the introduction of the sol into the accumulator cell a voltage is applied to the accumulator cell which forms active masses.
