Battery Binder Production Process

Why is a binder important for a battery?

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.

What is battery manufacturing process?

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.

Why is binder technology important for lithium batteries?

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.

How does a binder work?

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.

Do polymer binders improve battery safety?

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.

Do lithium-ion batteries have binders?

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.
