Thermodynamic and kinetic studies of LiNi0.5Co0.2Mn0.3O2 as a positive electrode material for Li-ion batteries using first principles

Abstract: Ni-rich Li-based layered Ni, Co, and Mn (NCM) materials have shown tremendous promise in recent years as positive electrode materials for Li-ion batteries. This is evident as companies developing batteries for electrical vehicles are currently commercializing these materials. Despite the considerable research performed on LiNiαCoβMnγO2 systems, we do not yet have a complete atomic level understanding of these materials. In this work we study the cationic ordering, thermodynamics, and diffusion kinetics of LiNi… Show more

“…As it follows from the results of at the interface as a result of oxidation reactions concomitant with the Li + extraction from NCA and other Ni-rich materials. 50 Possible Ni oxidation reactions in the course of charge are indicated in Figure 6c, 51 By comparing the differential capacity plots dQ/dV vs. potential of NCA-bare and coated NCA/LAO-2 electrodes for 2-nd and 50-th cycles by charging to 4.3 V (Figure 7), we conclude that similar transition metals oxidation/reduction peaks are developed for these electrodes in deintercalation/intercalation processes. It is important to note that LiAlO 2 coated electrodes demonstrate lower capacity fading upon cycling.…”

“…In addition, we note quite symmetric anodic/cathodic waves at ∼3.72-3.74 V of the Ni 2+ ↔ Ni 3+ reactions of these bare and coated samples with comparable potential differences suggesting thus similar electrode kinetics. By close examination of the differential capacity plots we note that the relative integrated area or anodic waves intensity (dQ/dV) 2 /(dQ/dV) 50 of the 2-nd and 50-th cycles at the above potentials (x = 0.3 in Li 1-x + diffusion into the bulk and oxidation/reduction reactions of the Ni-ions. The above phenomena described in Ref.…”

“…2,4 The investigation of the structural aspects of the material is a crucial issue to better understand the electrochemical properties of the LiCoO 2 compound. [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17] For example, the nature of the crystal, its size and shape, are directly related with its electrochemical characteristics. 2 The LiCoO 2 synthesized at low temperatures (LT), below 500 °C, presents a cubic spinel structure ( ), while the synthesis at high temperatures (HT) (above 500 °C), generates the rhombohedral structure with stratified layers ( ).…”
