ABSTRACT Energy storage and conversion technologies are crucial in the global shift toward renewable energy sources, addressing the intermittent nature of solar and wind energy and enhancing the stability and reliability of power grids. Polymer/carbon composites have emerged as pivotal materials in this realm, due to their unique ability to combine the electrical conductivity and mechanical strength of carbon materials with the versatility and chemical stability of conductive polymers. This review delves into how these methods affect conductivity, capacitance, and stability, thereby enhancing the efficiency and durability of devices such as supercapacitors and batteries. The discussion extends to the characterization of these materials using advanced techniques that elucidate their structural integrity and functional capabilities, providing insights into their performance enhancements. The applications of polymer/carbon composites in energy storage systems are highlighted by their use in supercapacitors and batteries, where they contribute to increased energy density, faster charge–discharge cycles, and improved longevity. As the demand for more efficient and sustainable energy storage solutions continues to grow, the insights provided by this review into the properties and applications of polymer/carbon composites pave the way for future innovations in energy technologies, ultimately guiding researchers and technologists in developing next‐generation materials for advanced energy systems.
