The utilization of carbon felt as the conductive material for the construction of a monosaccharide‐based coin‐cell biobattery is explored. Anthracene‐modified carbon nanotubes were used at the positive electrode to preferentially orientate laccase for direct electron transfer during O 2 reduction. A ferrocene‐modified poly(ethylenimine) redox polymer was used to electrically communicate with either glucose oxidase or fructose dehydrogenase at the negative electrode. The use of carbon felt helped in the immobilization of a larger quantity of enzyme. Cathodic and anodic currents with carbon felt electrodes showed a three‐fold and twofold increase, respectively, relative to the currents obtained with Toray paper materials. Bioelectrodes were assembled in a commercial coin‐cell battery casing and were tested as possible biobatteries. This work presents the first time in which a traditional battery design is used for the performance evaluation of different biobatteries.
