The glassy carbon electrode product of nano magnesium oxide has plenty of characters. For instance, good stability, excessive conductivity, and excessive purity. And there’s no fuel within the electrode, regeneration is simpler, the value is extra appropriate, and so forth. At current, as an expert magnesium oxide producer, the Meishen Know-how gave a top level view of the nano magnesium oxide for battery. At first, the lithium ion battery selects so as to add insoluble stable particle that diameter is between 0.05μm to 10μm, similar to TiO2, SiO2, Cr2O3, ZrO2, CeO2, Fe2O3, BaSO, SiC, MgO and so forth. It has many benefits, for instance, the excessive effectivity, excessive particular capability, secure cycle efficiency, and so forth. Subsequent, for lithium-ion battery cathode materials, taking nano magnesium oxide as electrical dopant, and made to anode materials with nanostructure. The precise discharge capability can obtain 240mAh/g. This sort of new kind anode materials is excessive power, security, and low worth. It’s appropriate for liquid battery and colloform battery, particularly for the ability battery with tremendous energy. After which, optimizing the capability and cycle efficiency of spinel manganic acid lithium. Taking spinel manganic acid lithium as anode materials, including nano magnesium oxide as acid elimination agent to take away acid. The additive quantity is from 0.5 to 20 % of bathtub answer quantity. After disacidifying bathtub answer, the HF content material of free acid within the bathtub answer can lower under 20ppm. Step one: taking the nano magnesium oxide because the PH regulator, and including it into the combined answer of cobalt salt and nickel salt. The second step: including lithium hydrate within the Ni-CO compound hydroxide, and warmth treating the combination below 280℃ to 420℃. The third step: the product from the second step is handled below the temperature of 650℃ to 750℃. Associated with coprecipitation time, the imply grain dimension of lithium composite oxide might be decreased or bulk density might be elevated. When the lithium composite oxide is taken as anodic lively materials, it will probably get a lithium ion secondary battery with excessive electrical capability. As well as, the precise additive quantity of magnesium oxide ought to rely upon the element combination listing.
