An electrolytic capacitor is a polarized capacitor whose anode is a positive plate where an 94 oxide layer is formed through electrochemical principles that limit the use of reverse voltage.
For high-energy storage with capacitors in series, some safety considerations must be applied to ensure one capacitor failing and leaking current does not apply too much voltage to the other series capacitors. Series connection is also sometimes used to adapt polarized electrolytic capacitors for bipolar AC use.
Here is a dc circuit with a battery using two electrolytic capacitors connected in parallel. The goal is to derive the formula for an equivalent capacitor. Each capacitor has holds a charge q, has a voltage V across it, and has a capacitance C, as shown in the diagram above.
Here we will see the series combination of capacitors. When the capacitors are connected in the form of series combination, then the capacitance in total will be less than the individual capacitances of the series capacitors. If one, two or number of capacitors are connected in series, then the overall effect will be the single capacitor.
You would hope they store the same energy as before with the series connection. $0.5CV^2$ for each gives 0.5*2.7*2.7*720 = 2624J, and 0.5*2.7*2.7*500 = 1824J, as before.

Capacitors can be separated from a battery, then connected in series. Because the capacitor is polarized, the positive terminal must be connected to a negative terminal. This creates correct polarity through the electrical circuit and prevents breakdown. Some electrolytic capacitors are unpolarized, meaning that either side can be positive or ...
When capacitors are connected in series, the total capacitance is less than any one of the series capacitors'' individual capacitances. If two or more capacitors are connected in series, the overall effect is that of a single (equivalent) capacitor having the sum total of the plate spacings of the individual capacitors.
