Improved rate and cycle performances of binder-free half-cells. (a) Rate capability of the binder-free and binder-containing positive half-cells, (NCM:f-LPS:AB:PPC = 80:20:4:3)/LPS/In-Li, operated at several current densities from 0.15 mA cm⁻² (0.17 C) to 3.0 mA cm⁻² (3.5 C) under CCCV charge-CC discharge between 3.7 and 2.0 V (vs. Li-In) at 30 °C. The numbers denote the operating current densities in mA cm⁻². Cycling retention of (b) binder-free positive half-cell shown in (a) operated at current density of 0.15 mA cm⁻² (0.17 C) under CCCV charge-CC discharge and (c) binder-free negative half-cell, (graphite:LS-LPS:AB:PPC = 58:42:2:3)/LPS/In-Li, operated at 0.064 mA cm⁻² (0.13 C) under CC charge-CC discharge.
