Here a simple design which could be developed for flat redox microbattery array with tunable output power is introduced. The fabrication of a V3+/Fe3+ redox microbattery using the gold compact disk (CD) as the electrode material and employing drilling technique to fabricate band electrodes is reported. The as-fabricated V3+/Fe3+ redox microbattery shows very attractive performance such as rechargeability, very high power and current density, low cost and simplicity of fabrication. Also microbattery arrays could be stacked very easily to achieve proper voltage, current and output power. Polarization and power curves and charge discharge cycles are obtained to characterize as-fabricated microbatteries. (C) 2015 Elsevier B.V. All rights reserved.
