چکیده
In plane micro-supercapacitors that are miniaturized energy storage components have attracted significant attention due to their high power densities for various ubiquitous and sustainable device systems as well facile integration on flexible/wearable platform. To implement the in practical applications can accompany solid state or gel electrolyte flexible substrates, ions must be readily transported electrodes achieving densities. Herein, we show large enhancement electrochemical properties of flexible, in-plane micro-supercapacitor using sharp-edged interdigitated electrode design, which was simply fabricated through direct laser scribing method. The allowed strong electric field induced at corners fingers led greater accumulation near surface electrode, significantly enhancing performance micro-supercapacitors. field-enhanced showed volumetric density 1.52 Wh L−1 excellent cyclability with capacitive retention 95.4% after 20 000 cycles. We further practicability our design by showing circuit applicability, mechanical stability, air stability. These results present an important pathway designing devices.

Cu Mesh for Flexible Transparent Conductive Electrodes
Copper electrodes with a micromesh/nanomesh structure were fabricated on a polyimide substrate using UV lithography and wet etching to produce flexible transparent conducting electrodes (TCEs). Well-defined mesh electrodes were realized through the use of high-quality Cu thin films. The films were fabricated using radio-frequency (RF) sputtering with a single-crystal Cu target--a simple but inn...
