Abstract

The invention relates to a super-iron alkaline cell which is provided based on the characteristic that an aqueous solution system of a chemical power supply of a positive electrode material for a super-iron cell is only a concentrated alkali solution. The cell comprises a shell, a positive electrode, a negative electrode, alkaline electrolyte and a diaphragm between the positive and negative electrodes; the negative electrode material is a ferric cathode, the positive electrode material is ferrate, and the electrolyte is prepared from 10-15wt% of NaOH or KOH solution and 85-90wt% of positive electrode material composed of the ferrate and magnesium boride or derivatives of the magnesium boride; and the open-circuit voltage of the cell is 1.6V-1.65V, and the working voltage is 1.2V-1.5V higher than 0.1-0.15V of the working voltage of a primary cell in the prior art. The cell is steady in discharging, safe and excellent in performance, has no pollution, and over 85% of the discharging time is between 1.2 V and 1.5V.

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. And the capacity of MnO2 is 308Ah / kg. High-iron primary batteries can be formed by replacing MnO2 in commercial zinc-manganese batteries with ferrate as the positive electrode material. Its battery reaction is: [0004] M...
