Sichuan HuangMing lithium power with annual output of 3000 tons of nanoscale lithium iron phosphate in deyang GuangHanShi project recently put into production. Using the original “project solvent liquid phase method for nano lithium iron phosphate” process at home for the first time, to realize the 50 nano lithium iron phosphate materials production, the industrialization high power charging and discharging, safety and cycling times index significantly more than existing products, and reduce the cost of lithium batteries, is expected to more than 20% of the country’s new energy vehicles for in the field of power battery, energy storage battery industry development to bring change.
Lithium battery anode materials in China of the lithium iron phosphate traditional production technology “solid phase method”, facing the high cost and the pollution big, batch production difficult and BiRongLiang difficult to control, quality poor stability problems.
In march this year, HuangMing lithium power independent research and development of “the liquid phase methods nano lithium iron phosphate production process” results through the appraisal. New technology is lithium iron phosphate/nano structure composites, many group doped lithium iron phosphate technology, fill our country can’t mass production quality stability, g is more than 150 ma/g capacity, recycling of 3000 or more of the blank of lithium iron phosphate, and put forward for the first time in normal temperature, atmospheric pressure “more solvent under the liquid phase methods” preparing nanometer lithium iron phosphate battery anode materials can be industrialization of technological process. This breakthrough, not only make the production cost decrease 20% above, and the service life of lithium battery power extend to 5 years or above, can at the same time satisfy the capacity and the requirements of the type of power, make new energy vehicle industry the first to benefit.
The Chinese academy GanYong, vice President of the new project, said not only realize our country in this field “in advance, the future will” starting line for new energy vehicles in the field of power battery, energy storage battery and bring change, and becomes a breakthrough new lithium power industrial chain.
According to GuangHanShi related development planning, it is estimated that by 2014 the project will attain annual capacity of scale. The future of lithium battery cost is expected to decline 30% above, realize the overall efficiency of the charging and discharging and frequency greatly enhanced, and promote lithium battery electric vehicles and wind power, photoelectricity, smart grid power battery pack the industry development.
