More Information
Summary:This invention relates to a waterborne fluoropolymer composition useful for the fabrication of Li-ion-Battery (LIB) electrodes. The fluoropolymer composition contains an organic carbonate compound, which is more environmentally friendly than other fugitive adhesion promoters currently used in waterborne fluoropolymer binders. An especially useful organic carbonate compound is ethylene carbonate (EC) and vinylene carbonate (VC), which are solids at room temperature, and other carbonates which are liquid at room temperature such as propylene carbonate, methyl carbonate and ethyl carbonate. The composition of the invention is low cost, environmentally friendly, safer, and has enhanced performance compared to current compositions.
