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, 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 that of ordinary batteries RN873 , GW240 . Particularly suitable choice 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.
Flat iron battery discharge curve. Such as Zn-K2FeO4, 70% or more of the discharge time in the 1.2-1.5V.
Rich in raw materials. The most abundant element in the crust for 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, Inspiron 1720 battery 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 as FeOOH or Fe2O3-H2O, non-toxic pollution, environmental-friendly. Does not require recycling.
Introduction Principles of High Speed Rail Battery Technology
Currently, countries in the world for the development of new energy vehicles to further reduce automobile exhaust pollution on the environment, to take different measures, some new energy constantly being used to modern cars, such as natural gas, hydrogen, electric energy, fuel batteries and fuel cells is that all auto manufacturers and research institutes devoted to studying the one direction.
In the current fuel cell technology, there is a new battery technology —– iron battery technology Latitude D620 battery .
Discussion at home and abroad with high iron battery lithium iron batteries and two iron pool. High-iron battery is a kind of synthesis and stability of ferrate (K2FeO4, BaFeO4, etc.) as a high-iron battery cathode materials, and has the energy density, small size, light weight, long life, no pollution of the new chemical battery; the other is lithium iron batteries, mainly iron phosphate FK890 batteries, open circuit voltage 1.78V-1.83V, operating voltage 1.2V-1.5V, the battery than a high 0.2-0.4V, and the steady discharge, no pollution, safety and excellent performance.
