Global best top 10 battery binder manufacturers
What is battery binder for lithium ion batteries?
As an important part of the lithium-ion battery electrode, the binder is mainly used to ensure a certain bonding strength between the active material particles and between the active particles and the current collector during the use of the battery, and is conducive to the formation of the SEI film.
In addition to the adhesive properties of general binders, lithium-ion battery electrode binder materials also need to be able to withstand the swelling and corrosion of the electrolyte. And withstand the electrochemical corrosion during the charge and discharge process, and remain stable within the working voltage range of the electrode.
Therefore, there are not many polymer materials that can be used as electrode binders for lithium-ion batteries, and the basic requirements are:
● Disperses the anode active material and conductive agent
● Thickening and anti-settling effect on anode slurry
● Stabilize the processing performance of the electrode and help improve the battery cycle performance
● Improve the peel strength of the pole piece
The following will sort out and analyze the global top 10 battery binder manufacturers, ranked in no particular order.
