Abstract
Pioneering work in bioelectrochemistry, particularly the employing of yeast cells to generate electrical current, had substantially favored the comprehension of bio electrochemical reactions. This foundational research has boosted the development of bio electrochemical systems (BES), which are significant for sustainable energy solutions. BES technologies, such as biobatteries, bio supercapacitors, and enzymatic and microbial biofuel cells, harness organic and biological systems to provide environmentally friendly alternatives for energy storage and conversion. Despite their potential, these technologies face challenges in achieving competitive energy densities and long-term stability compared to traditional accumulators and converters. Here, we introduce a new Ragone plot for BES, highlight the pathways to overcome key challenges, and compare BES with traditional technologies. A roadmap outlining future directions for BES development is also presented.
