=== Plant-based batteries and supercapacitors === | |||
{{Q|A '''[[w:supercapacitor|supercapacitor]]''' is a high-capacity [[w:capacitor|capacitor]] with a capacitance value much higher than other capacitors, but with lower voltage limits, that bridges the gap between [[w:electrolytic capacitor|electrolytic capacitor]]s and [[w:Rechargeable battery|rechargeable batteries]]. It typically stores 10 to 100 times more [[w:specific energy|energy per unit volume or mass]] than electrolytic capacitors, can accept and deliver charge much faster than batteries, and tolerates many more [[w:charge and discharge cycle|charge and discharge cycle]]s than [[w:Rechargeable battery|rechargeable batteries]].|Wikipedia|definition of a supercapacitator}} | |||
{{Q|Supercapacitors are used in applications requiring many rapid charge/discharge cycles, rather than long term compact energy storage — in automobiles, buses, trains, cranes and elevators, where they are used for [[w:Regenerative brake|regenerative braking]], short-term energy storage, or burst-mode power delivery.|Wikipedia|uses of supercapacitors}} | |||
