Abstract

The invention provides a cadmium ferrate alkaline battery, which is provided according to the characteristic that a water solution system of a chemical power source of a cathode material of a super-iron battery can only be a strong alkaline water solution. The cadmium ferrate alkaline battery comprises a housing, a cathode, an anode, alkaline electrolyte and a diaphragm, wherein the diaphragm is arranged between the cathode and the anode; the anode material is a cadmium anode; the cathode material is ferrate; the electrolyte is a NaOH or KOH water solution; the cathode material and the electrolyte comprise 10%-15% of NaOH or KOH water solution electrolyte and 85%-90% of the cathode material prepared from the ferrate and a Bi-Sr-Ca-Cu-O compound; the open-circuit voltage of the formed battery is 1.6V to 1.65V; the working voltage is 1.2V to 1.5V and is 0.1V to 0.15V higher than that of a primary battery in the prior art; the cadmium ferrate alkaline battery is stable to discharge, free of pollution, safe and excellent in performance; and the working voltage is 1.2V to 1.5V in over 85% of 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...
