Top 5 lithium battery anode binder manufacturers in China
As an important part of the lithium-ion battery electrode, the battery 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.
Commonly used binders for lithium-ion batteries mainly include polyvinyl alcohol (PVA), polytetrafluoroethylene (PTFE), polyolefins (PP, PE and other copolymers), and polyvinylidene fluoride (PVDF). They also include modified SBR rubber, fluorinated rubber, polyurethane, etc. This article will sort out the top 5 lithium battery anode binder manufacturers in China, including Lihong Fine Chemicals, Guangzhou Songbai Chemical, Eternal, Jingrui and Puyang Bluestar.
