Principle of high-iron battery technology
Currently, all countries in the world for the development of new energy vehicles to further reduce pollution from exhaust gases of vehicles on the environment to take different measures, some new energy sources continue to be used for modern cars, such as natural gas, rechargeable laptop battery hydrogen, electricity, fuel, batteries and car fuel cell is that the various manufacturers and research institutes dedicated to the study of single direction.
In the current technology of fuel cells, there is a new battery technology —– battery technology of iron.
Discussion of the iron battery at home and abroad with high-iron battery, and two kinds of lithium iron pool. High-iron battery is a kind of synthesis of stable ferrate (K2FeO4, BaFeO4, etc.) as high-iron battery cathode material, the high energy density, small size, light weight, dell inspiron 6400 battery long life, not polluting characteristics of the new chemical batteries, the other is the lithium-iron batteries, mainly iron phosphate batteries, the open circuit voltage 1.78V, 1.83V, 1.2V operating voltage 1.5 V battery Other high-0.2-0.4V, and the smooth evacuation, no pollution, safety and excellent performance.
Introduction of the technology stack of high iron
High-speed rail as a cathode material for battery, the electrode reaction for the three reactions of electrons, the electric potential of the battery and energy than traditional batteries, high zinc-manganese. And the low cost of these materials to the environment pollution-free, thus the attention of the electrochemical industry.
Hardware Ferrate in the cellular response can be E-3, so there is a relatively high capacity. As shown in Table 1, the high theoretical capacity of lithium iron 601Ah/kg up. sony vgp-bps10 battery The theory of capacity high speed rail barium has 313 Ah / kg. The capacity of MnO2 to 308Ah/kg.
Higher ferrite materials of the cathode to replace the commercial zinc-manganese batteries can be made of iron at high speed once the MnO2 batteries. The reaction of the cell is:
MFeO4 3 / 2Zn → 1/2Fe2O3 1 / 2ZnO + MznO2
Potassium is a high-batteries – zinc, iron and zinc – manganese discharge curve of the battery. No. 7 battery 0.5mA/cm2 current density discharge at constant current, cathode material K2FeO4 for Zn, the average discharge voltage is 1.58V. Zinc-voltage battery manganese is greater than the average discharge voltage (1.27V) 24%, the discharge capacity of the former than the latter 32%. In the above conditions, the discharge efficiency of 85%. Compared to conventional zinc-manganese batteries, apple a1280 battery iron speed once the battery has a high voltage (OPV: 1.9V), high energy (1.55Wh, AAA), do not consume electrolytes and non – environmental pollution and so on.
