Researchers in Germany have developed an on-chip Swiss-roll current collector made via the micro-origami process and infused it with a MnO2 slurry comprising a zincophilic binder. The zincophilic binder layer enhances zinc ion transportability and suppresses MnO2 dissolution. The MnO2 Swiss-roll microelectrode is used to create an on-chip microbattery with a small electrode footprint area which shows a footprint capacity up to 3.3 mAh cm–2 and has a capacity of more than 1 mAh cm–2 for 150 cycles. According to the researchers the battery stability can be improved to over 600 cycles at a 50% depth of discharge. The microbatteries provide adequate energy for ever more miniaturized intelligent microsystems…read more. Open Access TECHNICAL ARTICLE
