| description | The rapid development of new energy vehicles places a more and more urgent demand for high-performance lithium-ion batteries. As an important part of lithium-ion battery, the electrode performance has a significant impact on the overall performance of lithium-ion battery. In the electrode, the uniformity and stability of the slurry, which is a multi-component mixture, own a great influence on the performance of the electrode sheet. However, most of the current researchers’ interests are usually placed after the slurry process, that is, only focus on the performance of the electrode, but ignore the slurry which is the preconditions of the performance of the electrode. Uniformity of the electrode is determined by the uniformity and stability of slurries. However, as a complicated mixture of multicomponent suspended particles, it’s hard to measure the uniformity and stability of the slurry directly. At present, the rheological property test of the slurry is the most effective method to characterize the uniformity and stability of the slurry. In this paper, the effects of active materials, binders, conductive agents, solvents, dispersing additives, pH value, temperature, mixing steps on the rheological properties of the slurry during the manufacturing of lithium ion battery electrode pastes were reviewed. The influence of these factors on the rheological properties of the slurry was summarized, which provides a certain guiding role for fabricating slurries with higher uniformity and stability and developing high performance Li-ion batteries. |
