Grants for new energy vehicles promulgation of the method, with a lithium-ion laptop battery , nickel hydrogen and fuel cell and battery of three sources of new energy booming.
However, BYD independently developed iron battery “is the technology behind. The low carbon version developed by F3DM E6 electric vehicles and vehicles are equipped with iron battery”, is to become the F3DM first recommendation of the Ministry of Industry and Energy a new car, enjoy the plug-in hybrid grants for a maximum of 5 million policy.
BYD to “iron battery” has been classified as fuel cells, under national and international discussion of iron battery has a cell of iron and two lithium-iron. F3DM used iron battery “of battery lithium iron batteries is lithium iron phosphate.
The lithium phosphate is known is that by using iron phosphate lithium iron as cathode material for lithium-ion batteries. Ordinary batteries lead acid and nickel-hydrogen batteries as iron and lithium power cycle the battery life of their phosphate 4 times, up to 2000 times. The useful life of the lead-acid battery is “new for half a year for six months, six months, maintain and protect the most” will be 1 to 1.5 years in the same conditions, iron phosphate and lithium up to 7-8 years.
Safety in use, iron phosphate and lithium because of its high temperature properties (lithium iron phosphate peak temperature of 350 ℃ ℃ -500), even in the worst traffic accident would not explode, to ensure consumer safety.
Of course, iron phosphate and lithium is the most competitive of its ecological character. Since contains no heavy metals and rare metals, iron phosphate and lithium is therefore whether the production or in use, are non-toxic pollution.
Thus, as early as May this year, Daimler AG signed a formal joint venture agreement with BYD, a new joint venture Daimler Shenzhen BYD Co., Ltd., plans to launch a new electric vehicle in 2013. The model of joint venture with the BYD E6 battery will be used as the battery of iron. “
