Abstract

Better binders : Carboxymethyl cellulose (CMC) is the state‐of‐the‐art aqueous binder for carbon‐based supercapacitors, but it is inflexible, shrinks during drying, and cracks at high mass loadings. Mixtures of natural carbohydrates from potato starch and guar gum enable flexible yet high‐mass‐loading electrodes. Their electrochemical stability and performance are equivalent to CMC.
