As to the basic construction principles of electrolytic capacitors, there are three different types: aluminium, tantalum, and niobium capacitors. Each of these three capacitor families uses non-solid and solid manganese dioxide or solid polymer electrolytes, so a great spread of different combinations of anode material and solid or non-solid electrolytes is available.

Learn More(Higher-capacity capacitors use a 2.5-D storage at the expense of much less conducting plates). A capacitor stores charge, which means that when the capacitors discharges (delivers current), its voltage drops (linearly when the current is constant). A battery stores energy in chemical reactions.
