Abstract

The invention relates to an aluminum super-iron alkaline battery, which is provided according to the characteristic that an aqueous solution system of a chemical power source of an anode material of a super-iron battery can only be concentrated strong alkali aqueous solution. The battery comprises a shell, an anode, a cathode, alkaline electrolyte and a diaphragm which is arranged between the anode and the cathode, wherein a cathode material is aluminum, the anode material is ferrate, and the electrolyte is NaOH or KOH aqueous solution; the NaOH or KOH aqueous solution serving as the electrolyte accounts for 10 to 15 percent, and the anode material consisting of the ferrate, and magnesium boride or a derivative compound thereof accounts for 85 to 90 percent; the open circuit voltage of the battery is 1.6 to 1.65V and the working voltage is 1.2 to 1.5V which is 0.1 to 0.15V high than that of a primary battery in the prior art; and the battery discharges stably, is pollution-free and safe and has high performance, and over 85 percent of discharge time is in a period when the voltage is 1.2 to 1.5V.

Description

Technical field [0001] The invention belongs to a battery, especially a high-iron alkaline battery. Background technique [0002] When high-speed iron is used as the cathode material of the battery, the electrode reaction is a three-electron reaction, and the potential and energy of the battery are higher than that of the traditional zinc-manganese battery. Moreover, this material is cheap and does not pollute the environment, so it has received extensive attention from the electrochemical industry. [0003] Ferrate materials can obtain 3 electrons in the battery reaction, so they have a relatively high capacity. The theoretical capacity of lithium ferrate is as high as 601Ah / kg. The theoretical capacity of barium ferrate is also 313Ah / kg. The capacity of MnO2 is 308Ah / kg. Using ferrate as the cathode material to replace MnO2 in commercial zinc-manganese batteries can form high-speed iron primary batteries. The battery response is: [0004] MFeO4+3 / 2Zn→1 / 2Fe2O3+1 / 2ZnO+MznO2 [0...
