【摘要】 超声波可以提高锂电池浆料的混合效率与混合效果,但长时间的超声波作用可能会影响到锂电池浆料的稳定性。本方通过对PVDF与NMP形成的浆液进行不同时间的超声波处理,以及处理后的浆液进行不同时间的静置,研究了超声波处理时间对浆液粘度的影响程度,以及这种影响是否可以通过静置得以恢复,以期用于实际的生产指导。通过研究表明,超声波处理达到一定时间,会导致浆液的粘度的下降,同时,这种粘度的下降可以通过静置得到一定程度的恢复,通过静置恢复粘度有一定的局限,当超声波处理时间过长时,长的静置时间反而使粘度有所下降,因此静置时间最好控制在二、三小时左右。更多还原

【Abstract】 Ultrasonic can improve the mixing efficiency and mixing effect of lithium battery paste,but the long-term ultrasonic effect may affect the stability of lithium battery slurry.The influence of the ultrasonic treatment time on the viscosity of the slurry was studied by the ultrasonic treatment of the slurry formed by PVDF and NMP at different times,and the treated slurry was allowed to stand at different times.To be used for practical production guidance.It is shown that the ultrasonic treatment reaches a certain time,which leads to the decrease of the viscosity of the slurry.At the same time,the decrease of the viscosity can be restored to some extent by standing,and there is some limitation through the standing recovery viscosity.when ultrasonic processing time is too long,the viscosity will be declined,so the best time to control the standing time in two or three hours.更多还原
