First, lithium-ion secondary battery cathode material related technology transfer

The performance of cathode materials is the bottleneck restricting the development of lithium-ion battery, an urgent breakthrough. At present, the cathode material is mainly composed of lithium cobalt oxide, lithium manganate, lithium nickel cobalt manganate and lithium iron phosphate. Lithium manganate, lithium cobalt oxide and lithium iron phosphate as the cost advantage is more obvious, and non-toxic or low toxicity, lithium battery is gradually becoming the main direction of development.
 
　　
（1）High temperature lithium manganate
LiMn2O4 is rich in resources, cheap, and good security, no environmental pollution and other advantages as a lithium-ion battery cathode material has a unique advantage, is recognized as the twenty-first century, the most attractive lithium-ion battery cathode material The But its low capacity, and high temperature performance unhappy, in more than 55 ℃ environment capacity decay faster, restricting its large-scale application.

This project is aimed at this technical difficulty. The "doping + coating" modification of lithium manganate greatly improves the stability and cycle life of the high temperature environment. The product has the advantages of high performance and low cost, and the market competition Strength, preparation technology is mature, the investment risk is small. Potential applications include electric vehicles, electric bicycles and other transport, notebook computers and other electronic communications equipment, model aircraft, power tools and military, aviation, aerospace and other fields, the market prospects.

（2）Nickel cobalt manganate
    Nickel-cobalt-manganese oxide is one of the key materials for lithium-ion batteries. Lithium cobalt oxide is currently the most widely used battery material, but due to the shortage of cobalt resources, making it expensive, coupled with its use in the process of security risks, limiting its use in large-capacity batteries. Nickel-cobalt-manganese oxide with relatively inexpensive nickel and manganese to replace most of the cobalt, reducing the amount of cobalt, reducing the cost, but also improve the energy density, and other lithium-ion battery cathode materials lithium manganese oxide, lithium iron phosphate Compared to the nickel-cobalt-manganese oxide material and lithium cobalt oxide in the electrochemical performance and processing performance is very close, making nickel-cobalt-manganese oxide material into a new battery material and gradually replace the lithium cobalt oxide, has been in the small battery and power Type cylindrical lithium-ion battery is widely used.

（3）Lithium iron phosphate
   Lithium iron phosphate has a stable chemical structure, even in the case of over-charging does not occur side effects, and the electrolyte does not react, and thus has high safety. At the same time because it does not contain toxic metals, in full compliance with environmental requirements. Its long cycle life is also difficult to compare other cathode materials. However, the conventional production of lithium iron phosphate due to low tap density, low voltage platform, poor consistency of production batches, etc., limiting its use as a large-capacity lithium-ion battery materials, such as vehicle auxiliary power, electric vehicles, power grids Of the peak and valley adjustment, wind and solar power transmission and storage, emergency power reserves and other large energy storage devices.

　　The technology is simple, small pollution, less investment in equipment, low cost. Through the material modification, making the production of phosphate lithium battery cathode material with higher capacity, cycle performance and magnification characteristics, with broad market prospects and good social and economic benefits.

(1) Si / C composite anode material
    Carbon-based anode material because of good chemical stability, good cycle, no memory effect is the most common lithium-ion battery anode material, but its safety performance is relatively low, and the smaller specific capacity can not meet the battery small The requirements of the. Silicon material has nearly 10 times the traditional carbon anode material theoretical lithium storage capacity, attracted wide attention. However, the silicon material due to the charge and discharge process will produce several times the original volume changes, will cause the electrode powder and make the electrode failure, limiting the rapid development.
   In this technology, the silicon nanoparticles are encapsulated in the carbon hollow shell layer to form a core-shell structure, the carbon shell layer as a conductive medium, the use of carbon material porosity and volume buffer capacity to absorb or release the charge and discharge process of silicon material volume changes , To ensure that the charge and discharge process of silicon material and the close contact with the electrode, which effectively solve the silicon electrode cycle of the rapid failure of the problem, the product specific capacity> 800mAh / g, after the first charge and discharge cycle characteristics ~ 95%, with its Replace the traditional carbon anode will significantly reduce the battery size, will achieve a broad market prospects and economic benefits.
