Summary: Traditional graphite anode materials have low theoretical capacity and undergo easy lithium decomposition, while molybdenum disulfide is a promising anode material for advanced lithium-ion batteries due to its low cost, unique two-dimensional structure, and high theoretical capacity. However, poor conductivity and volume expansion during cycling hinder its practical application. In this study, monodisperse MoS2/graphite composites were prepared and investigated. The capacity of the composites increased with increasing MoS2 content, and reached the highest initial discharge capacity (832.70 mAh/g) at a MoS2:graphite ratio of 80%:20%. This simple and low-cost strategy has great potential for the development and production of advanced lithium-ion batteries.

Summary: This article presents the results of a systematic study on the electrochemical performance and mechanical changes in two types of commercial batteries with different anode chemistry. The study reveals that the swelling of anode layers in batteries with silicon-based components causes deformations in the jelly roll structure, but the presence of a small percentage of silicon does not significantly impact the cycling performance of the cells within the relevant state-of-health range for electric vehicles (EVs). The research suggests that there is room for improving the cell capacities by increasing the silicon loading in composite anodes to meet the increasing demands on EVs.

Summary: By coupling electrochemical testing to operando synchrotron based X-ray absorption and powder diffraction experiments, blended positive electrodes consisting of LiMn2O4 spinel (LMO) and layered LiNi0.5Mn0.3Co0.2O2 (NMC) were studied to understand their redox mechanism. It was found that blending NMC with LMO can enhance energy density at high rates, with the blend containing 25% LMO showing the best performance. Testing with a special electrochemical setup revealed that the effective current load on each blend component can vary significantly from the nominal rate and also changes with SoC. Operando studies allowed monitoring of the oxidation state evolution and changes in crystal structure, in line with the expected behavior of individual components considering their electrochemical current loads.
