::::With respect, I do think it would be appropriate to review the lead in light of the policy guidance that I have linked to above. Would it not be appropriate to cut the lead down to four paragraphs and remove the citation links from the lead as suggested? Could you also have another look at the opening para? To quote from MOS:INTRO: 'The subject should be placed in a context familiar to a normal reader'. I also suggest it is best to restrict the opening para to say what it 'is', and not what it 'is not'. As such, I suggest that the sentence 'As opposed to nanoscale dielectric capacitors[2] which also have high capacitance values, supercapacitors don't have a conventional solid dielectric' is unhelpful and should be bumped from the open para, and possibly out of the lead entirely.
