To me, an ultracapacitor should have lower ESR / high power – that is what it is chemically designed to be. You can increase the energy, but it causes increased ESR / lower power, and often lower cycle life. The proper system should have a high-power capacitor with a high energy battery, as that is what both chemistries were made to be.
Where batteries can supply power for relatively long periods, supercapacitors can quickly provide power for short periods. Supercapacitors are also environmentally friendly,
Supercapacitors are energy storage devices that can store and discharge electricity much faster than traditional batteries. They do this without relying on chemical reactions, which makes them more efficient and longer-lasting than standard batteries. When these supercapacitors are paired with solar cells, the result is a solar supercapacitor.
While Li-ion batteries commonly used in cell phones have a specific energy of 100-200 Wh/kg, supercapacitors may only store typically 5 Wh/kg. This means that a supercapacitor that has the same capacity (not capacitance) as a regular battery would weigh up to 40 times as much .
Solar supercapacitors take this concept a step further by combining a super capacitor battery for solar solar cells, Support for the Power Grid: AC Battery Storage systems can effectively supply stored solar energy to the grid during periods of peak demand. This capability can help to stabilize the grid and lessen our reliance on fossil

Although the specific energy of supercapacitors is defavorably compared with batteries, capacitors have the important advantage of the specific power. Specific power describes the speed at which energy can be delivered to the load (or, in charging the device, absorbed from the generator).
Supercapacitor specific power is typically 10 to 100 times greater than for batteries and can reach values up to 15 kW/kg. Ragone charts relate energy to power and are a valuable tool for characterizing and visualizing energy storage components.
Supercapacitors can therefore store 10 to 100 times more energy than electrolytic capacitors, but only one tenth as much as batteries. [citation needed] For reference, petrol fuel has a specific energy of 44.4 MJ/kg or 12 300 Wh/kg.
During charging cycles, supercapacitors only experience about 1 percent energy loss, compared to up to 30 percent for lead-acid batteries. Table 1: Comparison of key specification differences between lead-acid batteries, lithium-ion batteries and supercapacitors. Abbreviated from: Source.
The same goes for voltage delivery. A 12V battery might only provide 11.4V in a few years, but a supercapacitor will provide the same voltage after more than a decade of use.
