Summary: High-entropy oxides (HEOs) have emerged as a promising anode material for lithium-ion batteries due to their entropy-stabilized structure, regulable electronic structure, and high theoretical capacity. In this study, a nanoporous high-entropy alloy@high-entropy oxide (np-HEA@HEO) composite is synthesized, which exhibits optimized Li storage performance. Lattice distortions and oxygen vacancies in the as-synthesized samples contribute to rapid Li+ transport, and a large portion of pseudocapacitance contributes to the fast kinetics. DFT calculations demonstrate the regulation of Li+ adsorption/desorption behavior and reaction kinetics by reduced d-p band energy difference and spin-dependent synergy in HEO. These findings provide new insights into the features and properties of HEO for Li storage.

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.
