Lithium-ion battery binder research

Are polymer binders suitable for lithium-ion batteries?

This review introduces polymer binders that have been traditionally used in the cathode, anode, and separator materials of LIBs. 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.

What is a battery binder?

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).

Is a polymeric network a functional binder for lithium-ion batteries?

A Coordinatively Cross-Linked Polymeric Network as a Functional Binder for High-Performance Silicon Submicro-Particle Anodes in Lithium-ion Batteries. J. Mater. Chem. A 2014, 2, 19036–19045.

How does the binder affect the electrochemical performance of a battery?

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.

Does a binder swell a lithium ion?

Luo et al. addressed this aspect by investigating the degree of swelling in the electrolyte based on the type of binder used . A binder that allows for appropriate swelling in the electrolyte demonstrates a cooperative effect, enhancing lithium-ion movement and adhesion ability.

Can silicon-based anode binders improve battery energy density?

Introducing silicon-based anode materials to enhance battery energy density is an inevitable trend in the development of lithium-ion batteries, and optimizing and improving silicon-based anode binders is a very effective and promising way to solve the problems existing in silicon-based active materials.
