Research into innovative materials has been driven by the growing need for efficient and sustainable energy storage solutions. Among these materials, porous carbon aerogels have emerged as a prominent candidate. This talk explores the creation, characteristics, and uses of exotic porous carbon aerogels in high-efficiency energy storage devices. Porous carbon aerogels are synthesized by many procedures including the sol–gel process, hydrothermal approaches, and chemical activation. These methods allow for precise control over the size, distribution, and overall structure of the material’s pores. These aerogels possess remarkable characteristics such as large surface areas, low densities, and outstanding electrical conductivity, which make them well-suited for energy storage purposes. Because their interconnected porous structure allows for rapid ion and has a wide surface area, porous carbon aerogels in supercapacitors produce high densities of power and energy. Their superior cycle stability also guarantees long-term performance. These aerogels are effective anode materials and conductive additives for lithium-ion batteries (LIBs), enhancing electron flow and holding large lithium-ion volumes. Longer battery life is achieved by mitigating volume changes during lithiation and delithiation thanks to their structural stability. Carbon aerogels’ surface functional groups enhance pseudocapacitance in electrochemical capacitors (ECs), and hybrid devices that combine these aerogels with other materials provide movement-balanced energy and power density performance. The most recent developments in the synthesis and use of porous carbon aerogels will be highlighted, along with ongoing attempts to address current obstacles and investigate how these materials may completely transform energy storage technologies in the future. With further research and development, porous carbon aerogels have the potential to be a key component of reliable, long-lasting, and sustainable energy storage systems.
