Scaling up production and reducing manufacturing costs to compete with traditional energy storage technologies pose challenges for the widespread adoption of supercapacitors, requiring innovations in synthesis, processing, and manufacturing techniques.
In such a case, supercapacitor-battery hybrid energy storage can handle the voltage and frequency stability by supplying the auxiliary power from the battery and transient power from the supercapacitor . In microgrids maintaining a DC bus requires less complexity than maintaining an AC bus because it is efficient and cost-effective.
However, the efficient use of renewable energy sources and the emergence of wearable electronics has created the need for new requirements such as high-speed energy delivery, faster charge–discharge speeds, longer lifetimes, and reusability. This leads to the need for supercapacitors, which can be a good complement to batteries.
