Customer ServiceAs an indispensable part of the lithium-ion battery (LIB), a binder takes a small share of less than 3% (by weight) in the cell; however, it plays multiple roles. The binder is decisive in the slurry rheology, thus influencing the coating process and the resultant porous structures of electrodes.
In summary, although the binder occupies only a small part of the electrode, it plays a crucial role in the overall electrochemical performance of lithium-ion batteries. In this review, we provide a comprehensive overview of recent research advances in binders for cathodes and anodes of lithium-ion batteries.
While most of the research work has been focused on the development of anode and cathode active materials, other components of the battery also have a significant impact on the electrochemical performance of the battery. In particular, the binder plays an important role in stabilizing the microstructure and interface of the electrode and separator.
The binder is a critical component in both anode and cathode electrodes both for the electrochemical performance of the battery and the production process. The binder is a polymer that offers strong adhesion to the active materials (e.g., graphite), carbon additive (e.g., carbon black), and metal current collector (e.g., copper foil).
Furthermore, it explores the problems identified in traditional polymer binders and examines the research trends in next-generation polymer binder materials for lithium-ion batteries as alternatives. To date, the widespread use of N-methyl-2-pyrrolidone (NMP) as a solvent in lithium battery electrode production has been a standard practice.
When it comes to Li-O 2 batteries, the superoxide species are very aggressive and attack on conventional binder, resulting the fracture of electrode and the failure of battery performance. Thus, a chemical stable binder will alleviate the adverse oxidizing reactions and improve the property of battery.
