This company, a commercial unit of Ashland Inc., announced plans to show two new binders for lithium ion batteries at Battery Japan 2015, taking place February 25-27 in Tokyo. The company planned to launch Bondwell™ BVH9 carboxy methyl cellulose (CMC) binder for the anode, and will introduce its PVP K-Series polyvinylpyrrolidone (PVP) polymers as binders for ceramic-coated separators.

“Ashland produces Bondwell BVH9 CMC binder in our Jiangmen, China, facility and provides lithium ion cell producers in the Asia-Pacific region with a cost-effective binder that features optimized physical and electrochemical properties,” said Kenji Hanada, Tokyo-based senior marketing specialist for Industrial Specialties.

Bondwell BVH9 CMC binder is an aqueous binder for natural graphite anodes. Coin cells prepared with Bondwell BVH9 CMC binder have reportedly demonstrated significantly low impedance, as well as excellent capacity retention across a range of charge-discharge rates.

Bondwell BVH9 CMC binder is compatible with many commercial styrene butadiene (SB) latexes, and has good dispersion power for both natural graphite and conductive carbon black particles. It also reportedly adheres well to copper collectors.
