<i>In situ</i> growth of Cu(OH)₂@FeOOH nanotube arrays on catalytically deposited Cu current collector patterns for high-performance flexible in-plane micro-sized energy storage devices

Abstract

Rationally designed interdigitated electrodes based on Cu(OH)₂@FeOOH nanotube arrays are facilely converted <italic>in situ</italic> from catalytically deposited Cu current collector patterns for high-performance flexible micro-supercapacitor energy storage devices.
