MODERATORS
Electrolytic capacitors are closer to batteries than to non-polarized capacitors. Lithium-ion cells in capacitor housings also exist, presumably to evade tariffs and restrictions involved in shipping batteries.
They’re more of a hybrid technology. They have some great applications.
Like temporary storage when using regen from a car. They can buffer the energy and help with a rapid acceleration.
Dash cam in a car. They can charge the cap and in the event in a malfunction / event. The camera can continue to record.
Solar lamps. Charge during the day. Release energy during the night.
They’re poor at long term storage. Great at fast and temp storage.
