The alkaline chloroaluminium mixed solvent constant pressure sealed colloidal battery uses 50% to 80% glycerol low melting point aqueous solution as electrolyte solvent, and adds sodium hydroxide andsodium stannate into cathode solution; the alkaline chloroaluminium mixed solvent sealed colloidal battery is characterized in that the alkaline chloroaluminium mixed solvent is used as electrolyte solvent. Adding sodium perchlorate and sodium hydroxide into the anode solution; The cathode material is aluminum plate (rod, ring), and the anode material is graphite carbon black molded conductive plate (rod, ring). The cathodes of each group are insulated and sealed between the anodes, and the cathodes of the same group are separated from the anodes by an ion separator. The reaction of the discharge battery is 8Al + 3NaClO4+12H2O=8Al (HO) 3 (s) + 3NaCl: as shown in Figure 1.
