Batteries

finding solutions for a longer life

Ashland goes the extra mile when it comes to finding solutions and now we can help you do the same with longer-life batteries.  The rate of change in the world can leave some ideas in the rear-view mirror, but Ashland anticipates changing needs to stay one step ahead. It's not a 'plug 'n play' when you work with Ashland.  The Ashland solvers look at all the positives and negatives of possible solutions and technologies to find the one that best fits your need.  Recharge your products and markets through collaboration with Ashland.

Generating renewable energy from the sun and wind is a growing trend. How to effectively store this energy on a large scale is a growing challenge. The increased market for electric and hybrid vehicles creates an ever-growing need for longer-life batteries to expand the driving range.  Ashland thrives on putting science and chemistry to work to provide solutions to these and other challenges. As a leading supplier of a wide range of specialty additives and ingredients Ashland provides binders to the lithium ion battery (LiB) industry. Soteras™ MSi, a unique binder for high-capacity silicon-based anodes found in lithium ion batteries, is among the most recent innovations from Ashland. Able to be processed using standard industry practices, its ability to control swelling results in superior cycle performance yielding longer battery life.

featured products:

  • Soteras™ DSA dispersant for hydrophobic particles in water-based slurries
    Soteras™ DSA is an effective dispersant for aqueous systems for both the anode and cathode, including actives like lithium ion phosphate (LFP)

  • Soteras™ CCS-V binder for ceramic coated lithium ion battery separators 
    Soteras™ CCS-V binder enables separator producers to meet ever more stringent safety requirements from lithium ion battery cell producers. It employs Ashland’s unique 2-component cross-linking system:
    1. unique polymer which promotes adhesion to separator
    2. cross-linking agent to ensure thermal and mechanical stability

  • Soteras™ DSV dispersant
    Soteras™ DSV dispersant is a polymer dispersant for aqueous ceramic coated separators. Soteras™ DVS dispersant functions at low dosage to reduce the slurry viscosity.

Bondwell aqueous binder ensures effective anode slurry preparation and graphite binding Like the Aqualon™ products, the Bondwell BVH8 carboxy methyl cellulose (CMC) aqueous binder also acts as a rheology modifier for good slurry stability. It is typically used in conjunction with styrene butadiene (SB) latex to improve the binding strength of the active graphite on the copper collector. SB alone cannot generate slurry stability for the grap...

Bondwell™ aqueous polymers

Add Aqualon aqueous binders for effective anode slurry preparation and graphite binding Aqualon carboxy methyl cellulose (CMC) products perform as both aqueous binders and rheology modifiers. These CMC products are typically used in conjunction with styrene butadiene (SB) latex to improve the binding strength of the active graphite on the copper collector. SB alone cannot generate slurry stability for the graphite powder. The CMCs improve the rhe...
