Coprecipitation method is the main PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC preparation method for precursor materials, which can accurately control the content of each component and realize the atomic mixing of components. By adjusting the solution concentration, pH value, reaction time, reaction temperature, stirring speed and other synthetic parameters, materials with different particle size, morphology, density and crystallization degree can be prepared.
At present, cathode MATERIAL manufacturers mainly use coprecipitation-high temperature solid phase method to PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC preparation of cathode materials, that is, first through the coprecipitation method to obtain the precursor, and then mixed lithium sintering, the final preparation of the corresponding cathode material. The resultant materials are usually micron level spherical secondary particles composed of several sub-micron level primary particles.
However, with the increase of the battery charging and discharging times of secondary particles, especially under high voltage, the interface between primary particles is easy to produce micro-cracks or pulverization, improve the interface resistance, increase polarization, secondary spherical particles have more internal pores, large contact area, increase side reactions, and serious gas production, which leads to the deterioration of battery cycle performance and safety performance.
