How much nanomagnesium oxide is added to lithium batteries?

1. High-capacity tin composite negative electrode material additive for Lithium-ion battery Lithium-ion battery high-capacity tin composite negative electrode material is selected to add SiO2, TiO2, ZrO2, Cr2O3, Fe2O3, CeO2 with a diameter between 0.05. and 10 microns, MgO, SiC, BaSO and other insoluble solid particles 10 to 100 g/L; the nickel-solid particle-tin composite negative electrode material prepared by this method has a high specific capacity as an anode for lithium-ion batteries. first charge and discharge efficiency and stable cycle performance. 2. Lithium battery cathode material, using nano-magnesium oxide VK-Mg30D as a conductive dopant to prepare magnesium-doped lithium iron manganese phosphate by solid-state reaction, which further produces cathode material nanostructured with conductivity up to 10-2S. /cm, the capacity of decactual load reaches 240 mAh/g. This new cathode material has the characteristics of low price, high energy and safety. It is not only suitable for small and medium-sized lithium-ion polymer, colloidal and liquid batteries, but is especially suitable for high-power batteries. 3. For the cathode active material of rechargeable lithium batteries, a coating formed by adding a certain amount of VK-Mg30D nanomagnesium oxide, aluminum oxide and other metal oxides has a toughness of at least 3.5 MPam1/2 4. Improve spinel To determine the capacity and cycle performance of lithium manganese oxide batteries, add nano-magnesium oxide VK-Mg30D as a deacidifying agent to the lithium-ion battery electrolyte in which lithium spinel manganese oxide is used as the cathode material. 0.5- 0.5 - the weight of the electrolyte. 20%, by deacidifying the electrolyte, the content of free acid HF in the electrolyte is reduced to less than 20 ppm, which reduces the dissolving effect of HF on LiMn2O4 and improves the capacity and cycle. performance of LiMn2O4. 5. Nanomagnesium oxide VK-Mg30D is used as an alkaline solution as a pH regulator and ammonia solution as a complexing agent is added to a mixed aqueous solution containing cobalt salts and nickel salts to co-precipitate the Ni-Co composite hydroxide (b; ), add lithium hydroxide to the composite hydroxide, and heat treat the mixture at 280-420°C, and (c), heat treat the product obtained in step (b) at 650-750°C; Depending on the co-precipitation time, the average particle size of the lithium composite oxide decreases or the packing density increases accordingly. When this composite lithium oxide is used as an anode active material, a high-capacity lithium ion secondary battery can be obtained. LThe amount of magnesium oxide added is approximately 0.05%. 6. Glassy carbon electrode materials are generally polished with emery, cerium oxide, zirconium oxide, magnesium oxide and a-phase alumina. When polishing, they are always ground in order of the lower polishing agent particle size. VK-Mg30D nanomagnesium oxide glassy carbon electrode has the characteristics of high conductivity, good chemical stability, gas cannot pass through the electrode, high purity, low price , low hydrogen and oxygen surge and easy surface regeneration. it is widely used.
