Classification of Heat Evolution Terms in Li-Ion Batteries Regarding the OCV Hysteresis in a Li- and Mn-Rich NCM Cathode Material in Comparison to NCA

C/Li2MnSiO4 Nanocomposite Cathode Material for Li-Ion Batteries

A Search for the Optimum Lithium Rich Layered Metal Oxide Cathode Material for Li-Ion Batteries

We report the results of a comprehensive study of the relationship between electrochemical performance in Li cells and chemical composition of a series of Li rich layered metal oxides of the general formula xLi2MnO3 · (1-x)LiMn0.33Ni0.33Co0.33O2 in which x = 0,1, 0.2, 0,3, 0.5 or 0.7, synthesized using the same method. In order to identify the cathode material having the optimum Li cell perform...

a synchronic and diachronic approach to the change route of address terms in the two recent centuries of persian language

terms of address as an important linguistics items provide valuable information about the interlocutors, their relationship and their circumstances. this study was done to investigate the change route of persian address terms in the two recent centuries including three historical periods of qajar, pahlavi and after the islamic revolution. data were extracted from a corpus consisting 24 novels w...

DFT analysis of Li intercalation mechanisms in the Fe-phthalocyanine cathode of Li-ion batteries.

New materials with high intercalation capacity are needed for cathodic materials in order to overcome small capacities at high discharge rates in Li-ion batteries. High intercalation capacities have been reported in the experimental setup using iron phthalocyanine (FePc) as cathodic material; however the real intercalation capacity and the chemistry occurring during the intercalation process ar...

Phase stability of Li-Mn-O oxides as cathode materials for Li-ion batteries: insights from ab initio calculations.

In this work, we present a density-functional theory (DFT) investigation of the phase stability, electrochemical stability and phase transformation mechanisms of the layered and over-lithiated Mn oxides. This study includes the thermodynamic stability of Li and oxygen vacancies, to examine the electrochemical activation mechanisms of these cathode materials. The DFT calculations provide phase d...
