Carbon materials play a fundamental role in electrochemical energy storage due to their appealing properties, including low cost, high availability, environmental impact, surface functional groups, electrical conductivity, alongside thermal, mechanical, and chemical stability, among other factors. Currently, carbon can be considered the most extensively explored family field of supercapacitors batteries, which are devices covering wide range applications demanding power energy. However, as with all technologies, there is process adaptation optimization; hence, have been aligning advances that emerge. Similarly, over years, new methods processes discovered produce carbons more suitable for storage, adapting them present good synergy metal-based compounds meet current standards. In this work, we compilation used from inception these technologies day.
