The significance of developing implantable, biocompatible, miniature power sources operated in a low current range has become manifest in recent years to meet the demands of the fast-growing market for biomedical microdevices. In this work, we focus on developing high-performance cathode material for biocompatible zinc/polymer batteries utilizing biofluids as electrolyte. Conductive polymers and graphene are generally considered to be biocompatible and suitable for bioengineering applications. To harness the high electrical conductivity of graphene and the redox capability of polypyrrole (PPy), a polypyrrole fiber/graphene composite has been synthesized via a simple one-step route. This composite is highly conductive (141 S cm -1 ) and has a large specific surface area (561 m 2 g -1 ). It performs more effectively as the cathode material than pure polypyrrole fibers. The battery constructed with PPy fiber/reduced graphene oxide cathode and Zn anode delivered an energy density of 264 mWh g -1 in 0.1 M phosphate-buffer saline.

“…Hence, the development of new energy devices is important for a sustainable society. Innovative biofuel batteries, supercapacitors, and metal-air batteries are among the most suitable candidates to meet the energy storage demand [1][2][3][4][5][6]. Among the various power storage devices currently on the market, lithium-ion batteries (LIBs) have the best performance.…”

With the ever-increasing demand for power sources of high energy density and stability for emergent electrical vehicles and portable electronic devices, rechargeable batteries (such as lithium-ion batteries, fuel batteries, and metal–air batteries) have attracted extensive interests. Among the emerging battery technologies, metal–air batteries (MABs) are under intense research and development focus due to their high theoretical energy density and high level of safety. Although significant progress has been achieved in improving battery performance in the past decade, there are still numerous technical challenges to overcome for commercialization. Herein, this mini-review summarizes major issues vital to MABs, including progress on packaging and crucial manufacturing technologies for cathode, anode, and electrolyte. Future trends and prospects of advanced MABs by additive manufacturing and nanoengineering are also discussed.

“…Iako poseduju zadovoljavajuće elektrohemijske karateristike, ovi sistemi nisu komercijalizovani zbog degradacije katode na bazi PANI na potencijalima većim od 0,5 V, kao i zbog gubitka aktivnosti PANI na pH > 3. Pored PANI, polipirol (PPY), zahvaljujući elektrohemijskoj aktivnosti i stabilnosti u širokom opsegu pH, kao i visokim vrednostima specifičnog kapaciteta punjenja i pražnjenja od ∼140 A h g -1 , odnosno ∼90 A h cm -3 , razmatran je kao potencijalni elektrodni materijal superkondenzatora [5], katoda biokompatibilnih izvora električne energije [6,7], anoda u sistemima na bazi interkalacije litijuma u vodenim rastvorima [8,9] i polimer-polimer sistema [10]. Mada je PPY u teorijskom smislu intenzivno proučavan materijal, malo radova je posvećeno njegovom razmatranju u klasičnim baterijskim sistemima sa vodenim rastvorima elektrolita.…”

Polypyrrole (PPY) electrode was obtained by electrochemical oxidative polymerization of pyrrole on graphite electrode from aqueous electrolyte containing 0.1 mol dm?3 pyrrole monomer and 1.0 mol dm?3 HCl. Polymerization was achieved at the constant current density of 2 mA cm?2 during 1 h. The estimated active mass of PPY (assuming that the maximal doping degree of 0.33 was achieved and the polymerization efficiency of 100%) was 14 mg. Electrochemical characterization of PPY electrode was performed by galvanostatic experiments of charge (doping) and discharge (dedoping) with different current densities in the range between 0.5 and 1.5 mA cm?2. The experiments were performed in aqueous electrolyte containing 2.0 mol dm?3 NH4Cl and 1.1 mol dm?3 ZnCl2. Based on galvanostatic charge/discharge curves, following parameters of PPY electrode were evaluated: discharge capacity, specific discharge capacity, charge capacity, specific charge capacity, and Columbic efficiency. Both charge and discharge capacities were dependent on charge/discharge currents. The values decreased by increasing charge/discharge current, except for the lowest current density where Columbic efficiency exceeded 100%, which was explained by involvement of cations, from the electrolyte, in the doping process. An electrochemical cell in which PPY electrode served as a cathode and zinc electrode as the anode with an aqueous electrolyte containing 2.0 mol dm?3 NH4Cl and 1.1 mol dm?3 ZnCl2, was formed and relevant electrochemical and electrical parameters of the cell were estimated and discussed. Charge of the Zn|PPY cell was dependent on the charge/discharge current. Charge of the cell started between 0.5 and 0.7 V and proceeded up to 1.5 V, while the open circuit voltage of the fully discharged cell was 1.3 V. Specific discharge capacity of Zn|PPY cell, calculated based on discharge times, ranged from 95 to 70 mA h g?1, decreasing linearly with increasing discharge current density. On the other hand, calculated values of the theoretical capacity of the Zn|PPY cell was 105 mA g?1, meaning that practically 90% of the theoretical capacity can be achieved by discharging the cell with low current densities, while 67% of the theoretical capacity was obtained with the highest used current density. Based on Ragon parameters, the estimated values of specific energy that ranged between 46 and 68 W h kg?1, and the specific power between 125 and 380 W kg?1, Zn|PPY cell might be classified as a ?supercapattery?.
