The role of carboxymethyl cellulose on the rheology of anode slurries in lithium-ion batteries
Lithium-ion batteries are widely used in modern society, and research and development activities with the aim of further improving battery performance. The anode slurries in these devices typically include graphite as an active material and styrene-butadiene rubber as a binder, together with carboxymethyl cellulose (CMC) in water. Despite much effort to date, there is no agreement regarding the role of CMC. This mini-review summarizes the function of CMC based on prior research findings. The results of previous studies indicate that, at moderate concentrations, CMC can act as a dispersant but can serve as a thickener at high concentrations. Our experimental results suggest that steric and electrostatic repulsion effects play a crucial role in anode slurries. Also, we show that the preparation processes can drastically change the rheological properties of the slurries despite the same materials and the same composition being used.
期刊介绍:
Current Opinion in Colloid and Interface Science (COCIS) is an international journal that focuses on the molecular and nanoscopic aspects of colloidal systems and interfaces in various scientific and technological fields. These include materials science, biologically-relevant systems, energy and environmental technologies, and industrial applications.
Unlike primary journals, COCIS primarily serves as a guide for researchers, helping them navigate through the vast landscape of recently published literature. It critically analyzes the state of the art, identifies bottlenecks and unsolved issues, and proposes future developments.
Moreover, COCIS emphasizes certain areas and papers that are considered particularly interesting and significant by the Editors and Section Editors. Its goal is to provide valuable insights and updates to the research community in these specialized areas.
