“…), according to the Li + ion storage mechanisms. In several of examples described, general multiple conversion reactions for M x V y O z (M = Co, Cu, Mn, Fe, Zn, Ni) are preliminarily confirmed . These multiple electrochemical reactions are usually partially irreversible in low voltage region (i.e., 0–3 V), accompanying inevitable volume expansion and pulverization upon cycling, which severely hinder the practical application of these M x V y O z (M = Co, Cu, Mn, Fe, Zn, Ni) anode materials.…”

“…Upon charging, MnO was detected, corresponding reversible conversion between MnO and Mn upon lithiation/delithiation. Notably, γ‐Li x V 2 O 5 was retained in all charge/discharge processes, suggesting stable structure upon lithium ions intercalation/extraction (Figure c–f) . In the light of above phase transformation of Mn 2 V 2 O 7 upon lithiation/delithiation, possible electrochemical reactions can be proposed

Synthesis of Co₂V₂O₇ Hollow Cylinders with Enhanced Lithium Storage Properties using H₂O₂ as an Etching Agent

The construction of hollow structures has been used as an efficient strategy to improve electrochemical properties in lithium‐ion batteries (LIBs). In this paper, novel Co2V2O7 hollow cylinders have been fabricated via a unique etching process, in which H2O2 and CO(NH2)2 were selected as the etching agent and the release rate controlling agent, respectively. The formation process for the hollow structure and the etching mechanism have been investigated. Benefiting from the improved diffusion and transport of Li+, the Co2V2O7 hollow cylinder electrode demonstrates higher electrochemical performance as an anode material for LIBs than that of Co2V2O7 solid hexagonal prisms. Under a current density of 0.4 A g−1, the cycling capacity can be improved to 2.5 times greater than that of non‐etched hexagonal prisms.

Vanadates have received booming attention recently as promising materials for extensive electrochemical devices such as batteries and electrocatalysis. However, the enormous difficulties of achieving pure-phase transition metal vanadates, especially for nickel-based, hinder their exploitations. Herein, for the first time, by controlling the amount of ethylene glycol (EG) and reaction time, grape-like Ni 2 V 2 O 7 (or V 2 O 5 /Ni 2 V 2 O 7 ) microspheres were rationally fab-ricated. It is demonstrated that the EG can chelate both Ni 2 + and VO 3 À to form organometallic precursors. As anode in lithium-ion batteries (LIBs), it could deliver superior reversible capacity of 1050 mAh/g at 0.1 A/g and excellent rate capability of 600 mAh/g at 4 A/g. The facile hydrothermal synthesis broadens the material variety of nickel vanadates and offers new opportunities for their wider applications in electrochemistry.
