Microbatteries (MBs) are promising candidates to provide power for various miniaturized electronic devices, yet they generally suffer from complicated fabrication procedures and low areal energy density. Besides, all cathodes of current MBs solid state, the trade-off between capacity reaction kinetics restricts their wide applications. Here, we propose a dual-plating strategy facilely prepare zinc-bromine (Zn-Br 2 MBs) with liquid cathode achieve both high density fast simultaneously. The...
Multidimensional folded structures with elasticity could provide spatial charge storage capability and shape adaptability for micro-supercapacitors (MSCs). Here, highly crumpled in-plane MSCs superior conformality are fabricated in situ integrated by a fixture-free omnidirectional elastic contraction strategy. Using carbon nanotube microelectrodes, single MSC holds an ultrahigh volumetric capacitance of 9.3 F cm −3 , its total areal is 45 times greater than the initial state. Experimental...
Abstract Miniature batteries with programmable shape and scalable functions can provide new opportunities in the design of highly compatible integrated circuits flexible microelectronics. However, achieving these energy supply devices requires precise formation active electrode materials a high‐resolution patterned area using appropriate construction protocols. Here, shape‐customizable zinc‐based microbatteries (MBs) an all‐direct laser patterning (DLP) technique is demonstrated. Unlike...
Wireless-charging in-plane microbatteries (MBs) with conformal shape and high-capacity hold substantial promise in advancing the practical applications of complexly configured electronic devices. However, integrating these MBs seamlessly flexible system remains a challenge as it requires rational structure design reasonable materials engineering for micropower system, ensuring both high compatibility robust mechanical stability. Here, we present stretchable wireless-charging dual-plating...
Self-driven photodetectors based on flexible silicon nanowires (Si-NWs) array have attracted widespread research interests since they can continuously operate without external bias. However, their practical performances are limited due to the high density of intrinsic defects introduced by chemical etching procedure for Si-NWs. To address this issue, firstly ultra-thin wafers etched with metal-assisted method, and then Si-NWs obtained, finally a high-performance self-driven photodetector...
