lithium-ion battery innovation
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.

BLO™ gamma butyrolactone
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...
Bondwell™ aqueous polymers
Bondwell aqueous binder ensures effective anode slurry preparation and graphite binding 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 graphite powder. Bondwell BVH8 CMC imp...
Micropure™ EG solvent
Micropure EG (electronic grade) solvent, a high purity grade of N-Methyl-2-Pyrrolidone (NMP), is used to prepare solutions of polyvinylidene difluoride (PVDF) for use as a cathode binder. Cathode slurries produced with Micropure EG solvent have ideal characteristics for coating on aluminum foil and for use in a solvent recovery systems. Produced in a world-class ISO-accredited plant, Micropure EG solvent meets the exacting standards for low color...
NMP - N methyl 2 pyrrolidone (M-Pyrol™ solvent)
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...
PVP K series
Polyvinylpyrrolidone is a hygroscopic, amorphous polymer supplied as a white, free-flowing powder or a clear aqueous solution. Available in several molecular weight grades, they are characterized by K-value, and used in a great variety of applications. Polyvinylpyrrolidone can be plasticized with water and most common organic plasticizers. It is considered to be physiologically inert: Applications take advantage of one or more properties i...
