Magnesium Oxide for Battery

The glassy carbon electrode made of nano magnesium oxide has a lot of characters. For example, good stability, high conductivity, high purity. And there is no gas in the electrode, regeneration is easier, the price is more suitable, etc. At present, as a professional magnesium oxide manufacturer, Meishen Technology gave an outline of nano magnesium oxide for battery.

At first, the lithium ion battery selects to add insoluble solid particle that diameter is between 0.05μm to 10μm, such as TiO2, SiO2, Cr2O3, ZrO2, CeO2, Fe2O3, BaSO, SiC, MgO and so on. It has many advantages, for example, high efficiency, high specific capacity, stable cycle performance, etc.
Next, for lithium-ion battery cathode material, taking nano magnesium oxide as electric dopant, and made to anode material with nanostructure. The actual discharge capacity can achieve 240mAh/g. This kind of new type anode material is high energy, safety, and low price. It is suitable for liquid battery and colloform battery, especially for the power battery with super power.
And then, optimizing the capacity and cycle performance of spinel manganic acid lithium. Taking spinel manganic acid lithium as anode material, adding nano magnesium oxide as acid removal agent to remove acid. The additive amount is from 0.5 to 20 percent of bath solution amount. After disacidifying bath solution, the HF content of free acid in the bath solution can decrease below 20ppm.

The first step: taking nano magnesium oxide as PH regulator, and adding it into the mixed solution of cobalt salt and nickel salt.
The second step: adding lithium hydrate in the Ni-CO compound hydroxide, and heat treating the mixture under 280℃ to 420℃.
The third step: the product from the second step is treated under the temperature of 650℃ to 750℃. Related with coprecipitation time, the mean grain size of lithium composite oxide will be decreased or bulk density will be increased. When the lithium composite oxide is taken as anodic active material, it can get a lithium ion secondary battery with high electric capacity. In addition, the actual additive amount of magnesium oxide should depend on the detail mixture list.
