The invention relates to a cadmium super-iron alkaline battery, which is provided according to the characteristics that a water solution system of a chemical power supply of a positive electrode material of the super-iron battery can only be a dense alkali water solution. The cadmium super-iron alkaline battery comprises a shell, a positive electrode, a negative electrode, an alkaline electrolyte and a diaphragm which is arranged between the positive electrode and the negative electrode, wherein a negative electrode material is a zinc negative electrode; the positive electrode material is ferrate; the electrolyte is a NaOH or KOH water solution; in composition of the positive electrode material and the electrolyte of the battery, the electrolyte of the NaOH or KOH water solution accounts for 10-15%, and the positive electrode material consisting of the ferrate and magnesium diboride or a derivative compound thereof accounts for 85-90%; an open-circuit voltage formed by the battery is between 1.6V and 1.65V, and a working voltage is between 1.2V and 1.5V, which is improved by 0.1-0.15V compared with the primary battery in the prior art. The cadmium super-iron alkaline battery has no pollution, safety and excellent performance, is stable for discharging and has the voltage of 1.2-1.5V during more than 85% of discharging 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. 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...
