摘要
动态高温分解和低温分解结合使用合成的球形锰酸锂材料具有非常优异的电化学性能。工业化生产球形锂离子电池正极材料采用这种方法制备的产品质量可靠且成本较低。以醋酸锰、氢氧化锂、碳酸锰为基本材料,用液相法合成凝胶浆料和半固相浆料,利用喷雾干燥法制备了球形锰酸锂前驱体,最后动态焙烧喷雾干燥前驱体制备球形锰酸锂正极材料,并对其性能进行了计算机图像分析。
The electrochemical performance of spherical lithium manganate material which is synthesized by dynamic high temperature decomposition and low temperature decomposition is excellent. The quality of the products which is produced by the method of industrial production of spherical lithium ion battery cathode material is reliable with low cost. Manganese acetate, lithium hydroxide and manganese carbonate are as the basic materials. Gel slurry and semi solid slurry are synthesized by liquid phase. Spherical lithium manganate precursor was prepared by spray drying method. Finally, spherical lithium manganate cathode materials are prepared by dynamic baking spray drying precursor, and the performance image analysis is dealt with computer.
