The binder is decisive in the slurry rheology, thus influencing the coating process and the resultant porous structures of electrodes.
Commercial lithium-ion battery binders have been able to meet the basic needs of graphite electrode, but with the development of other components of the battery structure, such as solid electrolyte and dry electrode, the performance of commercial binders still has space to improve.
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.
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.
This review focuses on the crucial role of binders in battery electrode assembly and emphasizes the increasingly reduced use of toxic chemicals, such as NMP and DMC, which are commonly used in the preparation of non-aqueous binders, such as PVDF and PAN.
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.
