High-performance graphdiyne-based electrochemical actuators [PDF]

Nature Communications, 2018
AbstractElectrochemical actuators directly converting electrical energy to mechanical energy are critically important for artificial intelligence. However, their energy transduction efficiency is always lower than 1.0% because electrode materials lack active units in microstructure, and their assembly systems can hardly express the intrinsic properties.

Electrochemical Performance of Nanosized Disordered LiVOPO₄ [PDF]

ACS Omega, 2018
ε-LiVOPO4 is a promising multielectron cathode material for Li-ion batteries that can accommodate two electrons per vanadium, leading to higher energy densities. However, poor electronic conductivity and low lithium ion diffusivity currently result in low rate capability and poor cycle life.

Electrochemical Exfoliation of Graphene Oxide: Unveiling Structural Properties and Electrochemical Performance

Chemistry – A European Journal, 2023
AbstractAn electrochemical exfoliation method for the production of graphene oxide and its characterization by electrochemical techniques are presented here. Graphite rods are used as working electrode in a three‐electrode electrochemical cell, and electro‐exfoliation is achieved by applying anodic polarization in a sulfuric acid solution.
