What is an iron battery? What are the advantages of iron batteries

At present, there are two kinds of iron batteries researched at home and abroad: high-speed iron and lithium iron. BYD iron batteries seem to be the former. Except for BYD, no other manufacturer has claimed that its products can be put into practical use on a large scale. The high-speed iron battery is a synthetic stable ferrate (K2FeO4, BaFeO4, etc.), which can be used as the cathode material of the high-speed iron battery to produce a new type of chemical battery with high energy density, small size, light weight, long life, and pollution-free. The advantages of iron batteries: high energy and high capacity. At present, the specific power of civilian batteries on the market is only 60-135w/kg, while high-speed rail batteries can reach more than 1000w/kg, and the discharge current is 3-10 times that of ordinary batteries. Especially suitable for occasions requiring high power and high current. High-speed rail batteries are cost-effective. Alkaline manganese batteries cannot meet the requirements of digital cameras, video cameras and other electronic products that currently require high-current and large-capacity power. Lithium batteries are not very competitive in this regard due to cost. The high-speed rail battery discharge curve is flat. Such as Zn-K2FeO4, the discharge time of more than 70% is 1.2-1.5V. The raw materials are abundant. The most abundant elements in the crust are aluminum and iron. The content of iron in the crust is 4.75% and the content of manganese is 0.088%. At the same time, 3 mol electrons can be generated per mol+6 valence iron, while only 1 mol electrons can be generated per mol+4 valence manganese. The amount of iron is only 1/3 of manganese when it is very abundant, which greatly saves social resources. Reduce the cost of raw materials. On the market, MnO2 is about 9,000 yuan/ton, and Fe(NO3)3 is about 7,500 yuan/ton. Green and pollution-free. The product after ferrate discharge is FeOOH or Fe2O3-H2O, which is non-toxic, non-polluting, and friendly to the environment. Don't recycle.
