Biomass Battery Research 2.1. Basic Principles of Biomass Material Energy Cells The working principle of biomass material energy cells is mainly based on three aspects: electrode reactions, electrolyte conduction, and electrochemical reactions. As an electrode material, biomass undergoes oxidation-reduction reactions during the charge and discharge processes of the battery, enabling the storage and release of charges. As an electrolyte, biomass provides an ion-conductive environment inside the battery, allowing ions to migrate while blocking the electron pathway. The electrochemical potential difference formed between the two electrodes drives electrons from the negative electrode to the positive electrode. Ion movement in the electrolyte compensates for the charge, thereby achieving the conversion and output of electrical energy. By selecting suitable biomass materials for the electrodes and electrolyte, a battery system with a wide working voltage range and high specific capacity can be obtained (as shown in Figure 1). This working principle of biomass batteries provides the potential for their application in renewable energy storage. The working principle of a biomass fuel cell can be illustrated using a typical reaction with glucose as the substrate, where oxygen serves as the electron acceptor. After the reaction is complete, glucose is entirely oxidized.

Schematic Representation of the Working Principle of Microbial Fuel Cells 2.2. Early Examples of Biomass Material Fuel Cells Research Early research on biomass material fuel cells primarily 146 focused on microbial fuel cells. Kim et al. [1] investigated the electrochemical activity of several bacteria using cyclic voltammetry and assembled microbial fuel cells with these bacteria as catalysts. It is known that bacteria from the Geobacteraceae family can transfer electrons to solid electron acceptors like Fe(III) oxides while maintaining their growth. When electrodes are placed in such anaerobic environments, a continuous electric current is generated [2]. A team from the University of Massachusetts [3] discovered a microorganism capable of efficiently converting sugars into electricity. Booki Min et al. [4] invented planar batteries, which gained popularity among scientists for their novel battery structure. Derek R. Lovley et al. [5] replaced graphite rods with graphite felt and graphite foam as the anode of the battery, resulting in increased energy output. Park et al. [6] cultivated and enriched microorganisms with electrochemical activity using microbial fuel cells. These early studies laid the foundation for biomass microbial fuel cells and inspired further exploration of microbes and their electrochemical activity mechanisms. 2.3. Exploration and Application of Biomass Battery Prototypes Researchers have endeavored to construct various prototypes of batteries using biomass materials to achieve electrochemical energy conversion and storage, and they have initiated preliminary applications. Representative achievements include renewable lithium-ion and sodium-ion batteries prepared from cellulose and lignin, flow batteries using chitin and seaweed as raw materials, and cellulose- based supercapacitors. Biomass battery prototypes demonstrate high specific capacity, good cycling stability, and cost-effectiveness advantages. Some studies have explored the application of biomass batteries in areas such as wearable electronic devices and sensors, yielding reliable and feasible results. While the construction of biomass battery prototypes has laid the foundation for practical applications, challenges related to battery manufacturing scalability and cycle life persist, necessitating ongoing research and technological breakthroughs to propel the industrialization of biomass batteries. 2.4. Existing Biomass Fuel Cell Structures Currently, to optimize the electrical output of microbial fuel cells and meet various application scenarios, various microbial fuel cell structures have been developed, including upflow, cylindrical, and micro-type microbial fuel cells. To improve the utilization of the anode substrate, Lay et al. [39] constructed an upflow microbial fuel cell to recover electrical energy from wastewater. Wastewater is pumped into the anode chamber, and after microbial electricity generation at the anode, the treated wastewater is mixed with new incoming wastewater and returned to the anode chamber for secondary treatment. This recycling method enhances the utilization of organic matter in wastewater by the anode-producing microorganisms, resulting in increased electrical energy output from the upflow microbial fuel cell, with a maximum power density of (356±24) mW/m². However, due to the changing composition and flow conditions of the influent, the performance of upflow microbial fuel cells is somewhat unstable. Table 1. Classification of Biomass Fuel Cell Structures Type Structure Characteristics References Two- Chamber Type H-Shaped The cathode chamber and the anode chamber are placed horizontally, separated by an ion exchange membrane in between. 8 Upflow The cathode chamber is located at the upper end of the membrane, while the anode chamber is at the lower end. The bottom of the anode chamber has a circulating liquid inlet to ensure the recirculation of the anode liquid. 9 Micro-Type Most have volumes of only a few microliters, with an ion exchange membrane separating the cathode chamber and the anode chamber. 10 Single- Chamber Type Cubic The structure consists of a single anode chamber with an air cathode attached to the side of the anode chamber. 11 Cylindrical The cell has a cylindrical structure, and the cathode and anode are attached to the surface of the shell, providing a larger proton exchange area. 12 Deposit- Type The anode is buried in the sediment, while the cathode is submerged in the upper water layer, using the sediment- water interface as the ion migration interface. 13 Micro-Type Consists of only a single micro anode chamber, with an air cathode. 14 3.
