So far I haven't seen any reliable binder-free 3D cathode materials for Li-ion batteries, which can be cycled for more than 100 cycles.

Of course cathode materials continue to be a great problem because although there are many novel outstanding materials there are also new important systems requiring cathodes with much greater performances.
As per general answer, always every part of the existing device having scope. while for realistic actually, cathode materials is very important part of the energy device so till other materials improvement is going on cathode materials as well. actually cathode materials having two important work one related to keeping voltage difference second number of charge carriers transferring towards the anode.
This is a general question. At this stage it is bit hard to make a binder free cathode materials with high cyclability.
However, now we have good cathode materials for HEV, and EV vehicles...
