The commercial active material of carbon-coated LiFe 0.4 Mn 0.6 PO 4 (LFMP46 from S4R) was used as positive electrode material. The dried PEDOT:PSSTFSI was dissolved in N-methyl-2-pyrrolidone (NMP, Sigma–Aldrich) solvent for overnight at room temperature, the respective amount of active material was then added and stirred for 2 h minimum.
The average mass loading of the electrode was 3.5–4 mg cm −2. After drying, the positive electrodes were transferred into an Argon filled glovebox (< 0.1 ppm oxygen and −75 °C dew point) for coin cells’ assembly. Four different active material (AM) percentages were investigated, i.e., 80 wt.% AM, 85 wt.% AM, 90 wt.% AM and 94 wt.% AM.
Currently, one of the most commonly used binders at the positive electrode in standard Li-ion batteries is Poly (vinylidenefluoride) (PVDF). However, PVDF exhibits several limitations, including its non-polar structure, which restricts the range of compatible solvents.
