“…Another research direction involves application of novel highsurface area electrode materials and 3D-electrode matrix that may provide the improved bioelectrocatalysis of O 2 reduction both due to the increased surface amount of the electrochemically wired enzymes and enzyme stabilization at electrodes [3,6,[19][20][21][22]. Impressive results have been shown with different types of naked and modified carbon nanotubes (CNTs) electrodes, enabling to extract more than 1 mW cm À2 from biofuel cells exploiting laccase biocathodes [8][9][10]23].…”

“…It is commonly accepted that the most promising results are obtained with use of multicopper oxidases, among which the simplest oxidase, laccase, has been probably the most intensively studied due to its ability to catalyze effectively the reduction of oxygen directly to water at relatively low overpotentials [8][9][10][11][15][16][17][18]. Since proteins are macromolecules of largely developed and entangled structures, in which the catalytic centers are hidden inside the hydrophobic pocket, the distance between the enzyme's active center and the surface of electrode is usually too large for unimpeded direct transfers of electrons.…”

“…But, many electronic devices (e.g., portable music players, watches, wireless communication systems, medical equipment), even if designed on small-scale, require power demands changing drastically with operating mode. Having in mind a rather small power density offered by enzymatic systems (at best on the level of few mW cm -2 [8,9,11]), it is reasonable to expect that a typical biobattery would not be able to deliver current pulses required for certain applications. Further, higher loads may lead to significant reduction of the biobattery lifetime or, even, to the performance failure and irreversible damage.…”

“…The energy produced in a typical biofuel cell originates from redox reactions involving the oxygen reduction (at cathode) and oxidation of such an organic fuel as glucose or ethanol (at anode). More recently, there has been growing interest in hybrid biofuel cells known as biobatteries that are expected to produce higher open circuit potentials and power densities in comparison to the conventional biofuel cells [8][9][10][11]. The whole concept of operation of so called non-rechargeable zinc-air batteries is based on simultaneous oxidation of zinc at the battery-type anode and the oxygen reduction at the enzymatic cathode.…”

Integration of supercapacitors with enzymatic biobatteries toward more effective pulse-powered use in small-scale energy harvesting devices

et al. 2014

Effective integration of electrochemical devices consisting of enzyme-based biobatteries together with high power double-layer type capacitors is discussed here. An ultimate goal is to overcome a typical drawback of enzymatic power sources (biofuel cells and biobatteries): although their energy is potentially high enough to fulfill the needs of small electronic devices, their power is often too low. It is demonstrated that properly selected capacitor can support operation of such a low power device simply by supplying appropriate power pulses with fast dynamic response that is required for many applications involving fluctuating loads. Our model integrated system is obtained by coupling a series of double-layer capacitors with wellbehaved zinc/oxygen biobattery. The biobattery utilizes a stable cathodic material composed of covalently phenylated single-walled carbon nanotubes and the oxygen reduction enzyme, laccase, together with the hopeite-covered zinc rod acting as the anode. The enzymatic power source was characterized by the maximum power density of 1.8 mW cm -2 , the open circuit voltage of 1.6 V. Nevertheless, under the 50 X loading, the voltage of biobattery (electrode surface areas of ca. 0.3 cm 2 ) drops to 0 V after 2 s. The practical performance (power stability) of a biobattery has significantly improved by its parallel connection to electrochemical capacitor. The importance of such capacitor's parameters as low resistance (not more than a few hundred of milliohms), proper capacitance, and leakage current (not higher than a few microamperes) is emphasized here. The potential utility of the optimized biobattery/supercapacitor system is discussed in terms of use as a source of power to operate a digital watch.

Carbon paper covered with side-naphthylated multi-walled carbon nanotubes was used as the conducting support for the construction of a biocathode in a hybrid biofuel cell (biobattery). Laccase Cerrena unicolor enzyme was employed as the catalyst for the 4e reduction of oxygen and a zinc disc covered with hopeite was used as the anode. Derivatized carbon nanotubes increase the working surface of the electrode and provide direct contact with the active sites of laccase. Biobattery characteristics under externally applied resistance, and power-time dependencies under flow cell conditions were evaluated. The system including the sandwich biobattery powering a dedicated two-electrode minipotentiostat with a simple sensor electrode was employed for monitoring a model neurotransmitter-catechol. The biobattery-powered sensor yielded the oxidation currents linearly dependent on catechol concentration in the range 0-2 mM and with a correlation coefficient of 0.998. This type of biobattery with laccase as the cathode catalyst can be integrated with analytical devices and power them even in long-time monitoring experiments. Biofuel cells (BFC) and hybrid biofuel cells (biobatteries) have several advantages over conventional fuel cells, e.g. they use enzymesvery efficient catalysts to transform chemical energy to electrical energy. The attractiveness of biofuel cells is due to possibilities of variety of applications of high energy density biofuels such as ethanol, glycerol and carbohydrates, work at room temperatures, at pH close to neutral and the products of reactions are environmentally-friendly. [1][2][3][4] Enzymes are also less expensive than metallic catalysts used in conventional fuel cells and additionally are specific and selective, therefore do not require membrane separating electrode compartments. The biofuel cell can work as open-type device, and can be easily miniaturized. 4 Initial market opportunities for biofuel cells are likely to be where there is a need for large amounts of energy but low power demands. This is because biofuel cells can achieve high efficiencies for oxidizing a given fuel, providing high energy density, but have lower power densities due to lower catalytic activity compared to metal catalyst based fuel cells.3 An important area of applications of the biofuel cells is powering electronic devices, e.g. clocks, timers or toys, small medical devices such as biosensors and drug delivery systems. 5-9The number of enzyme molecules that can be directly bound to the conductive support is rather low, due to their large size leading to small surface concentration of catalytic active sites per electrode geometric area. Therefore application of a three dimensional conductive matrix is required. Carbon nanotubes increase the working surface area of the electrode and improve conductivity of the film. Furthermore, carbon nanotubes modified with different aryl groups provide easier access to the enzyme active sites and allow working in the direct electron transfer regime without any mediators.
