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.

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...

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...

BLO butyrolactone solvent, also known as gamma-Butyrolactone, is a polar solvent for ionic substrates and functions as an acid donor in aqueous media at elevated temperatures. Although BLO solvent is stable under a wide range of conditions, at elevated temperatures and in the presence of appropriate reagents, it serves as an intermediate in a variety of useful syntheses such as: Precursor to 2-pyrrolidone and the extensive family of alkyl pyrrol...

BLO™ gamma butyrolactone

M-Pyrol solvent, a lower alkyl pyrrolidone, is an extremely powerful and versatile aprotic solvent. With its high boiling point, low vapor pressure and high stability, it is an effective solvent in numerous industry applications and can be used as a co-solvent with water, alcohols and other organic substances. M-Pyrol solvent is extremely resistant to hydrolysis from pH 2-10, even at elevated temperatures. Beyond these limits, hydrolysis to 4-(me...
