Binder is an important part of the battery, the future development of the binder, or should start from the molecular structure design, the design of the binder needs to meet the following four requirements, in order to really get commercial application.
Figure 1 introduces the current state-of-the-art battery manufacturing process, which includes three major parts: electrode preparation, cell assembly, and battery electrochemistry activation. First, the active material (AM), conductive additive, and binder are mixed to form a uniform slurry with the solvent.
Binder is considered as a “neural network” to connect each part of electrode and guarantee the electron/Li + conductive pathway throughout the overall electrode matrix. Thus, binder technology is requisite in improving the overall characteristic of lithium batteries.
Binder works like a neural network connecting each part of electrode system and performs two major functions: the first one is to cohere active materials and conducting additive agent into integrity, as well as bind the matrix laminate and the current collector together.
In addition, the design of polymer binders with special functions, such as self-repair and flame retardant, can also improve the safety performance of battery. In Table 3, we list some of the polymer binders mentioned in this paper with other functions in addition to their excellent bonding and mechanical properties.
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.

Pack process – forming a module to fit for the models. This process is about making modular batteries with manufactured battery cells and putting them into a pack. First, battery cells are fixed side by side in a module case. The cells are connected and when a cover is put on the case, a module is complete. Lastly, finished modules are placed ...
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). The ...

In order to engineer a battery pack it is important to understand the fundamental building blocks, including the battery cell manufacturing process. This will allow you to understand some of the limitations of the cells and differences between batches of cells. Or at least understand where these may arise.
As 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. Usually, binders are considered to be inert in conventional LIBs. In …

The production of the lithium-ion battery cell consists of three main process steps: electrode manufacturing, cell assembly and cell finishing. Electrode production and cell finishing are largely independent of the cell type, while within cell assembly a distinction must be made between pouch cells, cylindrical cells and prismatic cells.

In addition, electrode thickness is correlated with the spreading process and battery rate performance decreases with increasing electrode thickness and discharge rate due to transport limitation and ohmic polarization of the electrolyte [40]. Also, thicker electrodes are difficult to dry and tend to crack or flake during their production [41].
