The glass carbon electrode made from nano oxide has a variety of characteristics, such as good stability of batteries, high conductivity, high purity, no gas in the electrode Essence. Easy surface regeneration, small hydrogen and oxygen potential, cheap price, etc. However, these are more generally said, so what are the specific effects of magnesium oxide in lithium batteries?
First of all, choose a 10-100g/L diameter of 10-100g/L diameter between 0.05-10 μm of TiO2、SiO2、Cr2O3、ZrO2、CeO2、Fe2O3、BaSO、SiC、MgO etc insoluble solid particles; the materials made as lithium ions have the characteristics of good charging and discharge efficiency, higher capacity, and stable circulatory performance.
Secondly, the lithium battery positive material, nano -magnesium oxide as a conductive dopant, generates magnesium doped lithium iron manganese phosphate through fixing reasons, and further forms a nano-structure of the positive electrode material. Its actual discharge capacity reaches 240mAh/g. This new type of positive electrode material has the characteristics of high energy, safety, and low prices. It is suitable for liquid and colloidal lithium-ion batteries, small and medium -sized polymers, especially for high -power power batteries.
Then, the capacity and cycle performance of spinel manganate lithium battery were optimized. In lithium ion battery electrolyte with spinel lithium manganate as positive material, nano-magnesium oxide is added as deacidifier to remove acid, the addition amount is 0.5-20% of the weight of electrolyte. By deacidizing the electrolyte, the content of free acid HF in the electrolyte is reduced to less than 20ppm, which reduces the dissolution of HF to LiMn2O4, and improves the capacity and cycle performance of LiMn2O4.
Finally, in the first step, nano magnesium oxide as a pH regulator is mixed with an alkali solution and an ammonia solution as a complexing agent, and added to a mixed aqueous solution containing cobalt and nickel salts to co-precipitate Ni-CO complex hydroxides.
The second step is to add lithium hydroxide to Ni-CO composite hydroxide, and heating treatment mixture at 280-420 °C.
In the third step, the product generated in the second step is heat treated in the environment of 650-750°C, which is related to the time of co-precipitation. The average particle size of lithium composite oxide decreases or the bulk density increases accordingly. When lithium composite oxide is used as the anode active material, a high capacity lithium ion secondary battery can be obtained, and the actual amount of magnesium oxide is subject to the specific formula.
