Cover Story: The groundbreaking semi-dry process for LFP cathodes reduces solvent usage significantly, validated with a 1 wt.% PTFE binder to minimize inactive material. Extrusion screws with multiple kneading zones intensify PTFE stress, increasing fibrillation. The process yields a flexible cathode layer with a specific capacitance of 155 mAh g⁻¹ at 0.1 C. Compared to conventional methods, it markedly enhances discharge capacity and overall energy output while reducing energy consumption. View this paper
