Non-polarized capacitors do not have a positive or negative terminal and can be connected to a circuit in any polarity. Polarized Capacitors: Electrolytic and Tantalum Capacitors. For optimal performance, you must …
Electrolytic capacitors are polarized, meaning they have a positive and negative terminal. Applying voltage in reverse polarity can lead to catastrophic failure, causing the capacitor to explode or leak electrolyte.
The only rule for polarized capacitors, such as electrolytic, tantalum etc., is that a potential on a positive ($+$) terminal is higher than the potential on a negative ($-$) terminal. If you reverse polarity, the polarized capacitor will most probably blow. That said, the capacitor doesn''t know what is "negative voltage".
Of course, many manufacturers will directly print the signs of-and + on the positive and negative terminals. 2.

The bottom of the aluminum shell is printed with ...
Axial cans will have a line on one side with arrows pointing to the negative lead, or an indented band that designates the positive lead. Surface mount tantalum chips will have a line and/or a notch on the positive end. Axial will have a notch on the positive side. Radial has either an arrow or positive indicator above the positive lead.
$begingroup$ For electrolytic capacitors, unless specifically designed to be insulated, the case (the metal surround) is usually connected to the negative terminal and somehow, through a conventional thought process, you could make an argument that marking the body (case) with the negative sign indicates that the case is negative as well as pointing to the …

Inside the electrolytic capacitor is an electrolyte material that stores electric charge. It has positive and negative polarity, which is similar to a battery, and it cannot be reversed. The positive electrode is a metal substrate with an oxide film. The negative electrode is connected to the electrolyte (solid and non-solid) through the metal electrode plate.
