Figure 1 summarizes the basic energy storage principles of supercapacitors with the classification as the basic framework and examines the research progress of electrode materials commonly used in recent years.
Supercapacitors can be charged and discharged quickly while the batteries can supply the bulk energy since they can store and deliver larger amount energy over a longer slower period of time.
HESS stores the excess of energy and reuses it when really needed. This paper describes the hybrid energy storage system that is suitable for use in renewable sources like solar, wind and can be used for remote or backup energy storage systems in absence of a working power grid.

In this article, we will introduce the principles and electrode materials of various types of supercapacitor battery, and summarize the applications and prospects of supercapacitor battery from a scientific and technological perspective.
The electrolyte is like the "transporter" inside the battery, helping to transfer ions between the electrodes and forming charge separation. The separator is responsible for separating the positive and negative electrodes, preventing short circuits, and allowing ions to pass through smoothly.
Unlike batteries, which rely on chemical reactions to store and release energy, supercapacitors use an electric field to store energy. This fundamental difference endows supercapacitors with several unique properties.
This study proposes a method to improve battery life: the hybrid energy storage system of super-capacitor and lead-acid battery is the key to solve these problems.

Supercapacitors represent the alternative to common electrochemical batteries, mainly to widely spread lithium-ion batteries. By physical mechanism and operation principle, supercapacitors are closer to batteries than to capacitors. Their properties are somewhere between batteries and capacitors.
Therefore, we will first briefly introduce the working principle of supercapacitors, and then explain in detail the energy storage mechanism between different electrodes and electrolytes.
The working principle of supercapacitors energy storage is to store electrical energy through the double-layer capacitor formed by charge separation at the interface between the electrolyte and the electrolyte. 2. Energy storage mechanism of supercapacitors
This paper presents the topic of supercapacitors (SC) as energy storage devices.

Table 2. The energy storage properties of BP-based supercapacitors. Nanostructured carbon-based materials like activated carbon, graphene, and CNTs offer significant effective surface areas, making them attractive for energy storage.
In addition, the energy density of supercapacitors is still much lower than that of batteries. This is due to the limited specific capacitance of electrode materials and the low solubility of electrolytes in the organic solvent.
