Abstract

The invention discloses an alkaline super-iron zinc battery based on the characteristic that an aqueous solution system of a chemical power supply of an anode material of a super-iron battery only can be concentrated alkaline aqueous solution. The super-iron alkaline zinc battery comprises a shell, an anode, a cathode, alkaline electrolyte and a diaphragm positioned between the anode and the cathode, wherein the cathode material is a zinc cathode; the anode material is ferrate; the electrolyte is the aqueous solution of NaOH or KOH; the electrolyte content is 10 to 15 percent; and the anode consists of ferrate and magnesium borides or derivative compounds thereof, and the anode content is 85 to 90 percent. An open circuit of the battery has the voltage of 1.6 to 1.65V, and the working voltage of 1.2 to 1.5V which is 0.1 to 0.15V higher than that of a primary battery in the prior art, is stable discharge electricity, pollution-free, safe and high in performance, and discharges the electricity under 1.2 to 1.5V for over 85 percent of the total discharge time.

Description

technical field [0001] The invention belongs to a battery, in particular to a high-iron alkaline battery. Background technique [0002] When high iron is used as the positive electrode 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 non-polluting to the environment, so it has received extensive attention from the electrochemical community. [0003] The ferrate material can obtain 3 electrons in the battery reaction, so it has 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. while MnO 2 The capacity is 308Ah / kg. Replacing MnO in Commercial Zn-Mn Batteries with Ferrate as Cathode Material 2 A high-speed rail primary battery can be formed. Its battery reaction is: [0004] MFeO 4 +3 / 2Zn→1 / 2F...
