Synthesis of high-iron battery is stable ferrate (K2FeO4, BaFeO4, etc.), high-iron batteries can be used as cathode material to produce the energy density, small size, light weight, long life and pollution-free new chemical battery.
Iron batteries advantages:
High-energy high-capacity. Currently on the market than the power of civil battery only 60 – 135w/kg, and high iron battery can reach 1000w/kg above, the discharge current is 3-10 times compared with the ordinary batteries. Particularly is suitable for high-power, high current situations. Cost-effective high-iron battery. Alkaline manganese batteries can not meet the current needs large-capacity high-current power digital cameras, cameras and other electronic products, the need for the cost of lithium-ion battery in this regard is not a strong competitive edge.
The iron battery discharge curve is flat . Such as Zn-K2FeO4, 70% or more of the discharge time is in the 1.2-1.5V.
The raw materials are rich. The most abundant element in the crust are the aluminum and the iron, iron content in the crust is 4.75%, manganese content is 0.088%. Iron per mol +6 also produce 3mol electronic, and each mol + 4 manganese could only produce 1mol electronics, the amount of iron is very rich in its own case, only Mn 1 / 3, a significant reduction in social resources, reduce raw material costs. MnO2 market about 9,000 yuan / ton, Fe (NO3) 3 about 7500 yuan / ton.
Green pollution-free. After discharge of ferrate product are FeOOH or Fe2O3-H2O, non-toxic pollution, environmental-friendly which do not require recycling.
