The advantages and process principle of iron battery are analyzed
The advantages and technical principles of iron battery are described
High speed iron battery is composed of stable ferrate (K2FeO4, BaFeO4, etc.), which can be used as positive data of high speed iron battery to produce a new type of chemical battery with high energy density, small size, light weight, long life and no pollution.
Advantages of iron batteries:
High energy, large 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 discharge current is 3-10 times that of ordinary batteries. Especially suitable for high-power and high-current applications. High-speed rail batteries are cost-effective. Alkaline manganese battery can not meet the demand of digital camera, Kaimela and other electronic products for high current, large capacity, and due to the cost problem, it is not competitive in this aspect.
The discharge curve of high-speed railway battery is relatively flat. Taking Zn-K2FeO4 as an example, the discharge time of 1.2-1.5V accounts for more than 70%.
Rich material. The most abundant elements in the crust are aluminum and iron, with 4.75% iron and 0.088% manganese. Since each mole of +6 iron can produce 3mol of electrons, while each mole of +4 manganese can only produce 1mol of electrons, the amount of iron itself is very abundant, only 1/3 of manganese, which greatly saves social resources and reduces material costs. MnO2 is about 9000 yuan/ton, Fe(NO3)3 is about 7500 yuan/ton.
Green and pollution-free. Ferrate FeOOH or Fe2O3-H2O emission products, non-toxic, pollution-free, environmental protection. No recall was requested.
High speed railway battery technology introduction
Now, the world’s new research and development, to further reduce vehicle exhaust pollution to the environment, using different methods, some new energy has been used in modern cars, such as natural gas, hydrogen, electricity, fuel and so on, the automobile manufacturers and research institutions will focus on the fuel power cell research in one direction.
In the current fuel cell technology, a new battery technology – iron cell technology has emerged.
At present, there are two kinds of iron batteries: high-speed iron batteries and lithium batteries. High-speed railway battery is a new type of chemical battery, which is composed of stable ferrite (K2FeO4, BaFeO4, etc.) as positive data of high-speed railway battery. It has the characteristics of high energy density, small size, light weight, long life, no pollution and so on. The other is iron lithium battery, important is iron phosphate battery, open circuit voltage is 1.78V-1.83V, working voltage is 1.2V-1.5V, 0.2-0.4V higher than other primary battery, stable discharge, no pollution, safety, excellent performance.
