Currently, polytetrafluoroethylene binders dominate dry processes, raising concerns about high fluorine content regarding restrictions on per- and polyfluoroalkyl substances. Moreover, the poor adhesion necessitates a wet coating-based primer layer, which dilutes its main objectives. Here, we show dry processing approach using a thermoplastic, fluorine-free binder with low environmental impact and high productivity. Parafilm® M, a laboratory sealing film formulated with low-cost paraffin and polyethylene, consists of saturated linear hydrocarbons, offering high chemical stability from strong C-H covalent bonds and a large highest occupied molecular orbital - lowest unoccupied molecular orbital energy gap. It also has a low glass transition temperature, enabling mild-pressure activation to interconnect active materials while achieving true solvent-free adhesion without the wet-coating of primers on the current collector. This dry electrode binder provides substantial electrochemical properties based on LiNi0.8Co0.1Mn0.1O2 positive electrode over 5 mAh cm−2 for 600 cycles. This integrated approach bridges the gap between materials and processes, paving the way for sustainable advancements in battery electrode manufacturing.
