STEM/EELS Analysis of Conversion Reactions in Cycled FeOF/C
Transition metal fluoride/carbon nanocomposites have been under extensive investigation in the past ten years due to their theoretical high capacity in the range of 500 to 800 mAh/g [1]. In this study, the structural changes of FeOF/C positive electrode during lithiation/delithiation have been studied as a function of number of cycles (up to 20) under constant cycling current of 50 mA/g and at ...
متن کاملInterdispersed Amorphous MnOxCarbon Nanocomposites with Superior Electrochemical Performance as LithiumStorage Material
The realization of manganese oxide anode materials for lithium-ion batteries is hindered by inferior cycle stability, rate capability, and high overpotential induced by the agglomeration of manganese metal grains, low conductivity of manganese oxide, and the high stress/strain in the crystalline manganese oxide structure during the repeated lithiation/delithiation process. To overcome these cha...
متن کاملStudy on the Electrochemical Reaction Mechanism of ZnFe2O4 by In Situ Transmission Electron Microscopy
A family of mixed transition-metal oxides (MTMOs) has great potential for applications as anodes for lithium ion batteries (LIBs). However, the reaction mechanism of MTMOs anodes during lithiation/delithiation is remain unclear. Here, the lithiation/delithiation processes of ZnFe2O4 nanoparticles are observed dynamically using in situ transmission electron microscopy (TEM). Our results suggest ...
متن کاملBismuth Oxysulfide and Its Polymer Nanocomposites for Efficient Purification
The danger of toxic organic pollutants in both aquatic and air environments calls for high-efficiency purification material. Herein, layered bismuth copper oxychalcogenides, BiCuSO, nanosheets of high photocatalytic activity were introduced to the PVDF (Polyvinylidene Fluoride). The fibrous membranes provide an easy, efficient, and recyclable way to purify organic pollutant. The physical and ph...
متن کاملTackling Reversible Conversion Reaction Mechanism for Lithium Based Battery
The demand for next generation of lithium based batteries with higher capacity and rate as well as increased cycle and calendar life requires new lithium storage and transfer mechanisms beyond what current lithium ion battery technique could provide. In lithium based battery, the lithium ions are stored in electrode materials either by physically intercalating (e.g. LiCoC2) or chemically alloyi...
