Nanoconfinement of ultra-small Bi₂Te₃ nanocrystals on reduced graphene oxide: a pathway to high-performance sodium-ion battery anodes

Abstract

Bismuth telluride (Bi2Te3) nanomaterials have attracted considerable attention owing to their intriguing physicochemical properties and wide-ranging potential applications arising from their distinctive layered structure and nanoscale size effects. However, synthesizing...

Direct regeneration of spent graphite anode material via a simple thermal treatment method

“…This suggests lithium can effectively diffuse internally under high scan rate conditions, meaning treatments can increase the lithium diffusion rate on the graphite surface to improve electrochemical performance. 53,54 To further understand the internal impedance and conductivity of the electrodes, electrochemical impedance spectroscopy (EIS) tests were performed. Fig.…”
