All-inkjet-printed, solid-state flexible supercapacitors (SCs) on paper are demonstrated as a new class of power sources with exceptionally versatile aesthetics. The inkjet-printed SCs look like letters or figures commonly found in office documents and aesthetically unitized other printed images paper.
The unending demand for portable, flexible, and even wearable electronic devices that have an aesthetic appeal unique functionality stimulates the development of advanced power sources excellent electrochemical performance and, more importantly, shape versatility. challenges in fabrication next-generation flexible mainly arise from their limited form factors, which prevent facile integration into differently shaped devices, lack reliable materials exhibit optimized attributes suitable...
The hierarchical porous structure has garnered considerable attention as a multiscale engineering strategy to bring unforeseen synergistic effects in vast variety of functional materials. Here, we demonstrate "microporous covalent organic framework (COF) net on mesoporous carbon nanotube (CNT) net" hybrid architecture new class molecularly designed, chemical trap for lithium polysulfides (Li2Sx) Li–S batteries. As proof concept the architecture, self-standing COF-net CNT-net interlayers...
Forthcoming flexible/wearable electronic devices with shape diversity and mobile usability garner a great deal of attention as an innovative technology to bring unprecedented changes in our daily lives. From the power source point view, conventional rechargeable batteries (one representative example is lithium-ion battery) fixed shapes sizes have intrinsic limitations fulfilling design/performance requirements for electronics. Here, facile efficient strategy address this formidable...
With the advent of ubiquitous electronics era, high-performance power sources with aesthetic diversity are indispensably needed as a key-enabling technology. Printed batteries have recently emerged crispy energy storage system to address this issue. fabricated through simple, low-cost, and scalable printing processes.

A monolithically integrated, single-unit PV–LIB device shows exceptional electrochemical performance that lies far beyond those achievable by conventional PVs or LIBs alone.
The rapidly approaching smart/wearable energy era necessitates advanced rechargeable power sources with reliable electrochemical properties and versatile form factors. Here, as a unique promising storage system to address this issue, we demonstrate new class of heterolayered, one-dimensional (1D) nanobuilding block mat (h-nanomat) battery based on unitized separator/electrode assembly (SEA) architecture. SEAs consist wood cellulose nanofibril (CNF) separator membranes metallic current...
The facilitation of ion/electron transport, along with ever-increasing demand for high-energy density, is a key to boosting the development energy storage systems such as lithium-ion batteries. Among major battery components, separator membranes have not been center attention compared other electrochemically active materials, despite their important roles in allowing ionic flow and preventing electrical contact between electrodes. Here, we present new class based on inverse opal-inspired,...
A solid-state electrolyte with reliable electrochemical performance, mechanical robustness and safety features is strongly pursued to facilitate the progress of flexible batteries.
