ChemInform Abstract: Investigation of Yttrium and Polyvalent Ion Intercalation into Nanocrystalline Vanadium Oxide.

Abstract

As indicated by the galvanostatic intermittent titration technique the reversible electrochemical intercalation of Y 3+ into nanocrystalline V 2 O 5 is feasible. The intercalation occurs with apparent gravimetric capacities exceeding that of Ca 2+ , Mg 2+ , or Li + over the limited voltage range 2.5-4.2 V (Li/Li + ). -(AMATUCCI, G.

Aerosol-assisted chemical vapor deposition of V2O5 cathodes with high rate capabilities for magnesium-ion batteries

“…The experimental data is represented by the symbols, while the data fitted by Z-view software by the solid lines. The Rct considered as the rate-determining step during the charge-discharge process [33]. Therefore, the smaller the diameter of the semicircle is, the smaller the Rct will be (higher specific capacitance).…”

Assessing Si-based anodes for Ca-ion batteries: Electrochemical decalciation of CaSi2

“…Among these, batteries based on multivalent charge carriers (M n+ ) can exhibit advantages in terms of energy density since for a certain amount of M carriers the capacity is doubled (n=2) or tripled (n=3) when compared to single valent carriers like Li + or Na + . Calcium is an attractive candidate [1,2,3] due to its low cost, natural abundance and low reduction potential. We have recently reported on the feasibility and reversibility of calcium plating in conventional alkyl carbonate electrolytes at moderate temperatures [4] which opens the way to the development of a new rechargeable battery technology using calcium anodes.…”

X-ray Absorption Studies of MnO2 Nanosheets as a Potential Cathode Material for Mg Secondary Battery during Electrochemical Cycling

“…The potential vs. Ag + /Ag was converted to that v.s. Mg 2+ /Mg according to previous report [4]. Discharge and charge capacities obtained in 0.4 M Mg(CF 3 SO 3 ) 2 / DMA were 319 mAhg -1 and 255 mAhg -1 respectively.…”
