Unfortunately, however, supercapacitors still have two main problems that remain since their inception: they can store 10-50 times less energy per kilo/liter than batteries (i.e. they are very bulky) and they are very expensive. As a result, the supercap industry has never really been thriving. Then li-ion came into the picture.
