Abstract

The invention relates to a method and a device for producing an accumulator having a fixed electrolyte. The inventive method is characterized by introducing an electrolyte in a flowable form into the accumulator cell and fixing the electrolyte and forming the active mass simultaneously inside the accumulator cell. The device for carrying out the inventive method comprises a filler head (1), an acid reservoir (3), a thickener reservoir (4), a metering pump for the acid (6.1+6.2), a metering pump for the thickener (5.1+5.2) and a flowmeter for the thickener (9.1+9.2) and the acid (10.1+10.2).
