The invention discloses a secondary starting method after batch stopping of electrolytic cells. The secondary starting method comprises the following steps: a, counting, recording and numbering anodes in different electrolytic cells in the same period in advance for unified management; b, hanging residual anodes at corresponding positions in the electrolytic bath according to the periodic table of the anodes, fixing the top ends of the guide rods in the form of sine and cosine function images, and ensuring that the bottoms and palms of the anodes are on the same plane; c, laying a combustion frame and a combustion nozzle on the electrolytic bath; d, heat preservation and sealing measures are taken between the electrolytic cell and the cathode, between the adjacent anodes and between the anodes and the electrolytic cell; e, roasting is conducted, and the temperature in the electrolytic bath is gradually increased to 950 DEG C; and f, after roasting is finished, electrolyte is poured into the electrolytic cell,
