Batteries & Energy Storage
DuPont Global Specialty Solutions (GSS) offers high-quality cellulosic polymers used as binders and technology enablers in Lithium Ion Batteries (LIBs). Other GSS polymers, such as POLYOX™ (poly-ethylene oxide) resins are on the forefront of technology development for Solid-State Batteries (SSBs) with functions of ionic conductivity and rheology control.
GSS supports its customers around the globe to develop, optimize and manufacture batteries and energy storage products.
Key Batteries & Energy Storage Applications
A common application of our cellulosic polymers is the use of TEXTURECEL™ Sodium carboxymethyl cellulose (Sodium CMC) as anode graphite binder. Our TEXTURECEL™ BA polymers have been specifically engineered to eliminate gel particles and optimize anode quality.
DuPont’s TEXTURECEL™ Sodium CMC polymers provide:
- Superior graphite binding and conductive additive in anode slurry
- Good adhesion on the anode copper foil
- Customizable viscosity and substitution level
- Low content of gel particles
- Binder, lubricant for advanced ceramics separators (METHOCEL™)
