Dual carbon engineering enabling 1T/2H MoS₂ with ultrastable potassium ion storage performance

Abstract

The 1T/2H MoS2@rGO@C prepared by dual carbon engineering and ammonia-assisted hydrothermal method exhibits the advantages of dual-phase coexistence and expanded interlayer spacing, and is expected to be an ultrastable potassium ion battery anode.

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.…”

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

“…It is accompanied by a notable increase in volume, which dramatically affects the electrode's structural stability while charging and discharging. 3,4 Consequently, the primary challenge faced by exploring suitable SIB anode materials lies in achieving excellent structural stability while accommodating volume changes induced by Na ion transport and providing rapid Na ion transport capabilities. 5,6…”
