Which binders are used in energy storage devices?

We review existing and emerging binders, binding technology used in energy-storage devices (including lithium-ion batteries, lithium–sulfur batteries, sodium-ion batteries, and supercapacitors), and state-of-the-art mechanical characterization and computational methods for binder research.

What binders can be used for lithium ion batteries?

In addition to the above commercial binders, other polymers with good mechanical strength, viscosity and ion conductivity are also suitable to be used as the graphite electrode binder for lithium-ion batteries.

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.

Why should you choose a chemical stable binder for Li-O 2 batteries?

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.

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 , , , , .

How to design advanced polymer binders for Li-ion batteries?

In general, the design of advanced polymer binders for Li-ion batteries should consider the following aspects: bond strength, mechanical properties, electrical conductivity, and chemical functionality.
