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 WALOCEL™ CRT carboxymethyl cellulose (CMC) as anode graphite binder. Our WALOCEL™ CRT BA polymers have been specifically engineered to eliminate gel particles and optimize anode quality.

DuPont’s WALOCEL™ CRT 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™)
