Capacitor Basics: How do Capacitors Work?
It also slows down the speed at which a capacitor can charge and discharge. Inductance. Usually a much smaller issue than ESR, there is a bit of inductance in any capacitor, which resists changes in current flow. Not a big deal most of the time. Voltage limits. Every capacitor has a limit of how much voltage you can put across it …

Self-Discharge in Electrochemical Capacitors: A Perspective Article
Self-discharge is the voltage drop experienced by the EC while stored in the charged state. The term self-discharge is sometimes associated with the chemical …
Role of Capacitor when switch is open in Buck Converter?
The capacitor is always being charged by the inductor, so it never has to support the load by itself. The duty cycle will remain essentially fixed regardless of output current once in CCM. In DCM, because the output current is less than half the inductor ramp current, the only way to regulate properly is to decrease duty cycle.
Physics A level revision resource: Introduction to capacitors
A battery stores electrical energy and releases it through chemical reactions, this means that it can be quickly charged but the discharge is slow. Unlike the battery, a capacitor is a circuit component that temporarily stores electrical energy through distributing charged particles on (generally two) plates to create a potential difference.
