Summary: Cyclic aging of lithium-ion batteries leads to capacity decline, impedance increase, and polarization deepening. A study was conducted on commercial 18650 lithium-ion batteries using fast charge/discharge cycles to determine the influence of cyclic aging on safety performance. The results showed a nonlinear three-stage change in aging, with higher charge/discharge rates exacerbating the aging state. Thermal abuse tests revealed that aged cells have better thermal stability but a higher risk of thermal runaway, possibly due to flammable gas and exothermic reactions during fast charge/discharge processes. This study highlights the potential for aged cells in products like electric vehicles to trigger thermal runaway.

Summary: This study comprehensively investigates the cyclic plasticity behaviour of the LiNixMnyCozO2 electrode subjected to cyclic lithiation/delithiation under constant mechanical load. The shakedown, ratcheting, and fatigue analyses were performed using direct numerical techniques, while coin cell electrochemical experiments were conducted to support the analysis. The effects of coating thickness on shakedown and ratcheting response, as well as the strain-fatigue life curve to predict active coating life, were studied. The numerical results confirmed the presence of low cycle fatigue at the center and ratcheting mechanism at the edge of the cathode, consistent with experimental findings.

Summary: The cycling performance of CoB coated NMC-811 cathode was evaluated in EC-EMC-based electrolytes with and without vinylene carbonate (VC) additive at different temperatures. The results showed that CoB coating can effectively protect the NMC-811 cathode at room temperature, but its protective capabilities are slightly reduced in the presence of VC. Additionally, high temperature and air shelving have negative impacts on the CoB coated material.

Summary: This study investigates the breathing behavior of solid electrolyte interphases (SEIs) induced by discharging/charging on Fe2O3 conversion-type anodes using cryogenic transmission electron microscopy and spectroscopy. The SEI breathing involves swelling and contracting upon lithiation and de-lithiation due to reversible compositional changes. Bare Fe2O3 anodes develop unstable SEI layers with thickness variation and excessive growth. By applying N-doped carbon coating on Fe2O3, a thinner and chemically more stable SEI layer develops, resulting in significantly enhanced cycling stability.

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.
