The conductive additive C65 (MTI) 20 wt% in electrode was added and mixed at 1500 rpm for 5 min. Silica powder, 60 wt%, was added to the mixer and mixed together for a further 10 min to give a viscous ink. The ink was transferred to a 10 mL Perspex ball mill vial and milled in a Spex M8000 Mill with a stainlesssteel bearing for 10 min.
