Review of the development of carbon-based battery

In todays society, people are increasingly aware of the importance of protecting the environment. In the past, some batteries and power generation methods were extremely harmful to the environment. So people began to seek sustainable energy sources, such as hydropower, solar power, and wind power. Among them, how to efficiently and sustainably store electric energy for these power generation methods while using the most environmentally friendly materials has become an important research direction. Carbon-based batteries have become the preferred energy storage device due to their many advantages, such as easy material acquisition, low cost, environmental protection and degradability. This paper mainly summarizes the advantages of carbon-based batteries such as simple and relatively mature preparation process, high stability and strong sustainability, as well as unit energy from the aspects of carbon-based supercapacitors, solar cells, solid-state batteries and bio-carbon-based batteries. This paper finds that shortcomings of carbon-based batteries such as low density and poor safety in special environments require further innovation in materials and processes. If the above shortcomings can be made up, carbon-based batteries will have huge application space.
