Lithium iron sony np-bg1 phosphate oxygen vacancy: According to independent research and development of a unique synthetic method to prepare a reversible storage capacity of 160mAh / g of oxygen vacancies lithium iron phosphate cathode material, recycling 500 times the capacity no attenuation, especially with a high magnification (10C) discharge capacity.
Lithium Cobalt Nickel Manganese: You can replace the lithium cobalt oxide lithium nickel manganese cobalt cathode material was successfully developed, the development of a unique lithium precursor synthesis and processing technology, 80% of the cobalt has been replaced by manganese and nickel, and realized its crystal particle size control, synthetic materials, a reversible capacity of 165mAh / g, higher than that of lithium cobalt oxide 10%, cycle life of up to 500 times, while the cost of less than 50% of lithium cobalt oxide has been in a small trial built on the basis of an annual output of 150 tons of pilot lines.
Improve the lithium nikon en-el3manganese oxide spinel: developed with independent intellectual property rights of a Al2O3 surface modification technology to produce a reversible capacity of 107mAh / g, 55 ℃ cycle capacity retention rate of 200 times greater than 90%, is the first one available in the hybrid battery with high power lithium-ion battery materials, protects the major projects of high-power electric vehicles, lithium-ion battery the smooth progress of the project.
Composite anode materials: development of a composite anode materials, reversible lithium storage capacity has reached 600mAh / g, reached the international advanced level.
Graphite Nano-Fiber Conductive Additives: To achieve the right carbon fiber diameter and length distribution of control, develop a graphite nanofibers conductive additives, solving the localization problem of nikon en-el4 such additives.
Battery Research: 2004 Star Constant this material-based high-power hybrid cars with lithium-ion nikon en-el4a batteries fully electric vehicles passed the 863 major projects testing the unity of the organization than the power reaches 1200W/kg, the performance ranking of international advanced level, star-heng 10Ah high-energy type and 7.5Ah high-power lithium-ion battery through the United States UL safety test, becoming the first Chinese mainland through a UL-certified Li-ion power digital camera battery, battery for this kind of paved the way for the international market.
