Nanomechanical Quantification of Elastic, Plastic, and Fracture Properties of LiCoO2
LiCoO 2 is an important lithium storage compound that adopts a distorted rock-salt structure of the α -NaFeO 2 type. After the discovery of reversible lithium (de)intercalation in this layered host compound by Mizushima et al., [ 1 ] this material became central to the introduction and subsequent development of lithium-ion batteries (LIBs) of high energy and power density. The advantages of LiC...
متن کاملElectronic spin transition in nanosize stoichiometric lithium cobalt oxide.
A change in the electronic spin state of the surfaces relevant to Li (de)intercalation of nanosized stoichiometric lithium cobalt oxide LiCo(III)O(2) from low-spin to intermediate and high spin is observed for the first time. These surfaces are the ones that are relevant for Li (de)intercalation. From density functional theory calculations with a Hubbard U correction, the surface energies of th...
متن کاملPreparation of Cobalt Oxide/Zinc Oxide Nanocomposite
Cobalt Oxide/ Zinc Oxide nanocomposite was synthesized by dropwise addition ofCo(NO)3.6H2O and Zn(NO3)2.4H2O solutions to KOH solution at different temperatures followed bycalcination at 300ºC for 4 h. The morphology and structure of nanoparticles and the influence oftemperature on particle size were studied using scanning electron microscopy (SEM) and X-RayDiffraction (XRD). Minimum particle s...
متن کاملElectrochemical behavior of LiCoO2 as aqueous lithium-ion battery electrodes
Despite the large number of studies on the behavior of LiCoO2 in organic electrolytes and its recent application as a positive electrode in rechargeable water battery prototypes, a little information is available about the lithium intercalation reaction in this layered compound in aqueous electrolytes. This work shows that LiCoO2 electrodes can be reversibly cycled in LiNO3 aqueous electrolytes...
متن کاملEnhanced electrochemical properties of fluoride-coated LiCoO2 thin films
The electrochemical properties of fluoride-coated lithium cobalt oxide [LiCoO2] thin films were characterized. Aluminum fluoride [AlF3] and lanthanum fluoride [LaF3] coating layers were fabricated on a pristine LiCoO2 thin film by using a spin-coating process. The AlF3- and LaF3-coated films exhibited a higher rate capability, cyclic performance, and stability at high temperature than the prist...
