Just a reminder...
"Due to environmental concerns, there is a significant demand for binders that are compatible with aqueous coating processes. CMC, polyacrylic acid (PAA) or polyvinyl alcohols (PVA) are each compatible with aqueous processing, but have drawbacks such as that they contain reactive hydroxyl groups that reduce stability and cause gas formation, contain impurities such as chloride, and/or have poor dispersant qualities. Other water dispersible binders in the form of latex particles such as SBR, PTFE and PVDF require dispersing agents to stabilise the latex particles, which can reduce the performance of devices, and often require the addition of adhesion promoters. These issues relating to binders in supercapacitors also apply in battery energy storage applications.
[0010] As the field of energy conversion and storage devices evolves and the applications become more demanding, there is an ongoing need for new components, including binders, that exhibit better stability and operational characteristics, including improved ESR performance, and/or that are compatible with environmentally friendly processing methods."
