I encounterd some difficuties in my experiment,and the most big question is that how is the eletrode prepared? According to the literatures, electroactive materials were mixed with PTFE and to yield a homogeneous paste .Then the paste was spread on the
current collectors. I want to know how could the electrode made by ? Is there need some special machine? and it seemed difficult to balance every electrode on its area, thickness as well as the weight of the electroactive materials. There are many pits on the surface of my electrode , and i can't manage to trim it . I would appreciate to receive your kind advices.
Best regards
