Are supercapacitors a viable alternative to batteries?
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.
Batteries or Supercapacitors? Why Not Both?
However, supercapacitors have a much lower energy density than batteries and are not suitable for applications that require long-term storage of energy. Supercapacitors also have a high self-discharge rate, meaning they will lose a good chunk of their charge when not in use, and are typically more expensive than batteries.
