Abstract The design and development of self-charging supercapacitor power cells are rapidly gaining interest due to their ability convert store energy in an integrated device. Here, we have demonstrated the fabrication a using siloxene sheets as electrodes siloxene-based polymeric piezofiber separator immobilized with ionogel electrolyte. properties fabricated device subjected various levels compressive forces showed self-charge up maximum 207 mV. mechanism process is discussed via...
Tailoring the properties of transition metal-based layered double hydroxides is inevitable for high-performance energy storage and efficient urea-electro-oxidation reaction (UOR) effectively harnessing from urea-rich wastewater.
The two-dimensional 1T-MoS2 quantum sheets (QSs) continuously seek attention due to their extraordinary energy harnessing and storage properties towards designing an all-in-one self-charging power system (SCPS). Herein, we have utilized the superior dual-functional nature of exfoliated MoS2 QSs for SCPS via fabricating all-solid-state microsupercapacitors (MSC) as device triboelectric nanogenerator (TENG) with based charge-trapping interfacial layer harvester. electrochemical analysis MSC...
Soft robotics has developed rapidly in recent years as an emergent research topic, offering new avenues for various industrial and biomedical settings. Despite these advancements, its applicability is limited to locomotion actuation due the lack of adequate charge storage system that can support robot's sensory challenging conditions. Herein, ultra-flexible, lightweight (≈50 milligrams), wirelessly rechargeable micro-supercapacitor onboard power source miniaturized soft robots, capable...

Abstract An advanced energy autonomous system that simultaneously harnesses and stores on the same platform offers exciting opportunities for near‐future self‐powered miniature electronics. However, achieving optimal synchronization between power output of an harvester storage unit or integrating it seamlessly with real‐time microelectronics to build a highly efficient remains challenging. Herein, unique bimetallic layered double hydroxide (LDH) based tribo‐positive layer is introduced...
Abstract Aqueous Aluminum‐air batteries (AABs) hold promise for advancing high‐energy density storage systems in future technologies. However, their widespread practical deployment is limited by the inherent hydrogen side reactions Aluminum (Al) and incomplete cathodic reactions. To address these challenges, Al‐sodium persulfate (Na 2 S O 8 ) system introduced as an alternative to traditional AABs. Utilizing Na allows simultaneously achieve three critical objectives, namely, eliminating need...
ABSTRACT Tailoring atomically dispersed single‐atom catalyst (Fe‐SAC) holding well‐defined coordination structure (Fe‐N 4 ) along with precise control over morphology is a critical challenge. Herein, we propose novel acid‐amine coupling reaction between metal‐chelated ionic liquid ([1‐(3‐aminopropyl) 3‐methylimidazolium tetrachloroferrate(III)] [APIM] + [FeCl ] − and carboxylic groups of carbon allotropes (C = GO, CNT, CNF, vX‐72) to precisely immobilize Fe‐N x sites. Out designed...
