Supercapattery-Diode: Using Layered Double Hydroxide Nanosheets for Unidirectional Energy Storage.

The supercapacitor-diode (CAPode) is a device that integrates the functionality of an ionic diode with that of a conventional supercapacitor. The unique combination of energy storage and rectification properties in CAPodes is relevant for iontronics, alternate current rectifiers, logic operations, grid stabilization, and even biomedical applications. Here, we propose a novel aqueous-phase supercapattery-diode with excellent energy storage [total specific capacity () = 162 C g, energy density = 34 W h kg at 1.

Unconventional Synthesis of Metal (Ni, Co, Ag) Antimony Alloy Particles.

Bimetallic alloy materials attract interest owing to their properties and stability compared to pure metals, especially alloys with nanoscale dimensions. Metal antimony (MSb) alloys, specifically NiSb, are widely used for charge storage applications due to their high stability. Most synthetic approaches to form these materials require drastic conditions (e.

Crumpled B, F Co-doped graphene nanosheets for the fabrication of all-solid-state flexible supercapacitors.

Crumpled B, F co-doped graphene nanosheets (BFGO) have been synthesized using supercritical water as the solvent in a short reaction time of 1 h and were demonstrated for the fabrication of all-solid-state flexible supercapacitors (ASFS). As-synthesized BFGO delivered high specific capacitance with an NaVO/HSO electrolyte (832 F g). Moreover, the fabricated ASFS showed excellent energy and power densities of 24 W h kg and 800 W kg at 1 A g, respectively.
