New Energy Battery Binding

Why is a battery binder important?

Among all battery components, the binder plays a key role in determining the preparation of electrodes and the improvement of battery performance, in spite of a low usage amount.

How do binders and conductive additives affect battery energy density?

Traditional binders and conductive additives set up channels for electrons and ions transport to improve the redox reactions in the electrode, while it is inevitable to increase the loading of inactive components and results in an obvious decrease in the energy density of battery [ 81, 82, 83, 84 ].

What role does a binder play in a lithium-ion battery?

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.

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.

Do batteries need binders?

Although binders are a critical component of batteries, they are typically ignored by battery engineers [11, 27]. However, the rising demand for high-energy-density rechargeable batteries has focused attention on binders. Binders are made of polymeric materials and account for approximately 5 wt% of the total battery weight .

Can multifunctional binders improve the energy density of batteries?

However, to improve the energy density of batteries, various strategies have been adopted to design multifunctional binders, which are able to combine dual or multi benefits from each single polymer and provide additional functionality beyond binding the electrode integrity , , , , .
