Analysis of 3V Button battery process technology and production applications

 

SEM images of 3V Button battery precursors at different magnifications at different reaction times The control of the precursor reaction atmosphere has a great impact on the quality of the precursor product, including the morphology, crystal structure, and impurity content of the precursor. Manganese has many valences, including +2, +3, +4, +6, and +7. In an acidic environment, Mr12+ can exist stably, but in an alkaline environment, Mn2+ is easily oxidized to a high-valent manganese compound. The chemical formula of divalent manganese hydroxide is Mn(OH)2', which is a white or light pink crystal. Mn(OH): will be quickly oxidized into a brown compound when exposed to air: 2Mn(OH)2+02=2MnO(OH) Even trace oxygen dissolved in water can oxidize Mn(OH):. If the dissolved oxygen in the pure water used for the precursor reaction is not removed, or if the reaction slurry is directly exposed to air during the reaction, the precursor slurry will be severely oxidized, and its color will be dark brown or black. In this case, a qualified precursor cannot be reacted. Figure 7-27 shows the SEM image of the ternary precursor prepared without nitrogen protection during the reaction process, and its metal ratio is Ni: Co: Mn = 5: 2: 3. As can be seen from the figure, the morphology of the precursor is blocks of different sizes and their agglomerates. The tap density of the product is very low, only 0.62g'cm-3. The SEM of the precursor without nitrogen protection during the reaction process is the XRD of the NCM precursor reacted under different atmosphere conditions. It can be seen that the crystal structure of the precursor reacted under air atmosphere and the precursor under nitrogen protection is very different. There is also a situation that in the late stage of the reaction or when the reaction is about to end, oxygen enters the reaction system for various reasons, resulting in the SEM images of Nio.sMrio. Co. . . : (OH)2 reacted at different solid contents. (a) and (b) are the precursors reacted at a solid content of 20%, and (c) and (d) are the precursors reacted at a solid content of 10%. It can be seen that the morphology of the product at 20% solid content is relatively regular, and the surface of the secondary particles is relatively dense. (a) Solid content 20% (b) Solid content 20% (c) Solid content 10% (d) Solid content 10% NiO.SMn0.3C00.2(OH) produced at different solid contents: The precursors of other components of the ternary materials also have the same rules. SEM images of Nio7MnoisCoo. ,5(OH)2, in which (a) and (b) are precursors reacted at a solid content of 20%, and (c) and (d) are precursors reacted at a solid content of 10%. (a) Solid content 20% (b) Solid content 20%
