Something anout the Iron battery
Iron batteries advantages:
High-energy high-capacity. Currently on the market, the power of civil battery only has 60 – 135w/kg, and high iron battery can reach 1000w/kg above, the discharge current are 3-10 times than ordinary batteries. it is particularly suitable for the high-power and high current situations. The high-iron battery is cost-effective. 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 flat . Such as Zn-K2FeO4, 70% or more of the discharge time in the 1.2-1.5V.
The raw materials are rich. The most abundant element in the crust are the aluminum and iron, iron content in the crust is 4.75%, manganese content of 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 is about 9,000 yuan / ton, Fe (NO3) 3 is about 7500 yuan / ton.
Green pollution-free. After discharge of ferrate product is FeOOH or Fe2O3-H2O, non-toxic pollution, environmental-friendly. Does not require recycling.
