Since rapidly increasing energy demands have aroused tremendous research activities on energy storage and conversion, microorganisms (e.g., bacteria, fungi, and viruses) have played significant roles in developing high‐performance electrodes due to their strong abilities of fast reproduction, biomineralization, gene modification, and self‐assembly. Recently, a large quantity of bacteria and fungi has been utilized as the precursors to produce heteroatom–doped carbons or as the biofactories and templates to biomineralize the metal ions to form carbon‐based composites. In addition, in virtue of easy genetic modification, nanoscale viruses with functional groups are directly used as biotemplates for the self‐assembly of the active materials. In this review, a detailed introduction on the microorganisms and their unique abilities as well as the mechanisms behind their operations are discussed. Moreover, recent progress on bacteria‐ and fungi‐derived carbon materials and their composites, as well as the virus‐templated bio‐materials as the electrodes in electrochemical fields, including batteries and electrocatalysts, are further summarized. Finally, challenges and perspectives on the development of the microorganism derivations in electrochemical fields are also provided. This review offers guidance for the rational design of advanced electrode materials from microorganisms and extend the energy systems from the man‐made to biofabrication.

“…The sulfur/carbon hybrid material had a high initial capacity of 1490 mAh g −1 at 0.1 C. The excellent electrochemical performance was mainly attributed to the large specific surface area that provided enough space for the deposition of insulating Li 2 S 2 /Li 2 S, and the marcohollow core could adapt to the large volume expansion of sulfur during the lithiation process. Li et al [64] . used yeast as a carbon source to successfully obtain nitrogen‐rich porous carbon microspheres (with a nitrogen content of 8.52 %) using hydrothermal method and nitrogen doping.…”

Lithium‐sulfur (Li−S) batteries have attracted attention in the field of energy storage due to their high energy density and theoretical capacity. However, there are still some obstacles to achieve commercial applications such as large volume expansion of sulfur, low electrical conductivity, the growth of lithium dendrites, and the polysulfide shuttle effect. Through continuous research on Li−S batteries, renewable biomass materials have been discovered by scholars and scientists due to their sustainable development, low cost, and extensive sources. The results showed that renewable biomass‐derived carbons had outstanding advantages such as high specific surface area and large pore volume, as well as inherent heteroatom doping after being applied to Li−S batteries, which had a significant effect on improving the electrochemical performance. This Review summarizes the research progress of Li−S batteries in renewable biomass materials in recent years, starting from three aspects: biomass carbon‐sulfur composite cathodes, biomass modified separators, and biomass independent flexible carbon interlayers. Firstly, the Review summarizes its physical barrier and adsorption mechanism (the effect of various porous structures), chemical reaction and adsorption mechanism, catalysis and conversion mechanism. Then, it classifies materials based on the source of renewable biomass as well as elaborating and analyzing the structures, mechanism, and performance among them. Finally, the Review summarized the shortages in this field, as well as the challenges and opportunities faced. The authors hope that this Review will have a certain reference value for the development of various biomasses for high performance Li−S batteries, and will inspire more scholars to devote themselves to the research of biomass materials for Li−S batteries.
