Lithium battery cathode material, nano magnesium oxide as conductive dopant, through solid reaction to generate magnesium doped lithium iron manganese phosphate, and further made into nanostructure anode material, its actual discharge capacity reaches 240mAh/g.

This new cathode material has the characteristics of high energy, safety and low price, suitable for liquid and colloidal lithium ion batteries, small and medium-sized polymers, especially for power batteries with high power.

Optimize the capacity and cycling performance of spinel lithium manganate battery. In the electrolyte of lithium ion battery with spinel lithium manganate as the anode material, nanometer magnesium oxide is added as the deacidifier to remove the acid, and the added amount is 0.5-20% of the electrolyte weight.

By removing acid from the electrolyte, the content of free acid HF in the electrolyte is reduced to less than 20ppm, reducing the solubility of HF to LiMn2O4, and improving the capacity and cycling performance of LiMn2O4.

In the first step, nanometer magnesium oxide was mixed with alkali solution as pH regulator and ammonia solution as complexing agent, and was added to mixed aqueous solution containing cobalt salt and nickel salt to co-precipitate Ni-CO composite hydroxide.

In the second step, lithium hydroxide was added to ni-CO compound hydroxide and the mixture was heat-treated at 280-420?. In the third step and the second step, the products generated are heat-treated in an environment of 650-750?, which is related to the time of co-precipitation. As a result, the average particle size of lithium composite oxide decreases or the bulk density increases.

When the lithium composite oxide is used as the anode active material, a lithium ion secondary battery with high capacity can be obtained, while the actual amount of magnesium oxide added depends on the specific formula.

Meishen is the world's leading producer of magnesium oxide, Magnesium oxide is an oxide of magnesium, an ionic compound. It is a white solid at room temperature. Magnesium oxide exists in the form of periclase in nature and is a raw material for magnesium smelting. Magnesium oxide is white or light yellow powder, odorless, tasteless, this product is insoluble in water and ethanol, melting point 2852 ° C, boiling point 3600 ° C, magnesium oxide has high refractory insulation properties. It can be converted into crystal by burning at a temperature above 1000 ° C. If it rises above 1500 ° C, it will form a burnt magnesia or sintered magnesia.

Magnesium oxide can be used in the manufacture of metallurgy, smelting, advanced magnesia bricks, refractory materials and moisturizing materials. It is also widely used in rubber, rubber sheet, rubber products, pharmaceutical industry, food industry, plastic sheet accelerator, glass fiber reinforced plastics and Surface coating of silicon steel sheet, paper production, steel ball polishing, leather treatment, insulation materials, grease, dyes, ceramics, desiccant, resin, flame retardant, etc.

Hebei Meishen Chemical Technology Group is the main magnesium oxide producer in the world. It is also the largest magnesium salt producer in China and has won the ISO9002 quality system certification. It also has GMP-Certification.

With rich experience in the research, development, production, management and operation of magnesium oxide products, Meishen Group has always attached great importance to the research and development of new products and strict requirements on product quality. Meishen has a high-level sales team. The business covers more than 20 countries and regions around the world. It is widely welcomed by new and old customers.
