Summary: In this study, a hierarchical micro-nano hydrangea-like NiCo2O4/V2O3 composite array (NCO/VO) was prepared on a nickel foam substrate as a free-standing anode for lithium-ion batteries (LIBs) using a facile one-step hydrothermal method combined with heat treatment. The introduction of V2O3 to form a composite structure with NCO improved the electronic and ionic conductivity of the electrode. The synergistic effect of porosity, composite structure, and micro-nano architecture resulted in excellent electrochemical performance of the electrode. The as-prepared electrode exhibited a specific capacity of 1155.6 mA h g-1 after 200 cycles at a current density of 100 mA g-1, with a retention ratio of 91.02%. At a higher current density of 1000 mA g-1, it delivered a specific capacity of 750 mA h g-1, demonstrating excellent rate performance. This work highlights NCO/VO-NF as a promising candidate anode for next-generation LIBs.

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.
