Summary: An integrated framework of modeling and experiments was developed to explain the capacity fade of a lithium-ion battery with CuCo2O4 as the anode. Simulation results suggest that the dissolution of active material plays a critical role in capacity fading, and the interactions between SEI formation and active material dissolution determine the battery life.

Summary: Polymers can spontaneously adsorb onto high-energy substrates from liquid solutions, forming configurationally complex and durable phases with higher durability than expected. Controlling the physical, chemical, and transport properties of these interphases is crucial for advancing energy storage technology. In this study, the interfacial adsorption of oligomeric polyethylene glycol (PEG) chains in different liquid electrolytes was analyzed, revealing an optimum polymer molecular weight of approximately 400 Da for achieving the highest columbic efficiency in both Zn and Li deposition. These findings provide a simple and versatile approach for extending battery lifetime.

Summary: Considering use cases and selecting the right features are crucial in developing battery lifetime prediction models. Prediction of cell-to-cell variability between identically cycled cells requires features that are not reliant on cycling conditions. While features encoding cycling conditions can boost model accuracy, they may lead to reduced transferability on identically cycled cells.

Summary: This study reveals that low discharge rate leads to accelerated capacity fade, while high discharge rate results in more significant kinetic loss. It further identifies that the kinetic loss in high discharge cells primarily occurs in the cathode, while accelerated capacity fade in low discharge cells is mainly caused by degradation in the anode. SEM images also indicate worse interphases and dense agglomerated structure due to cycling the anode at a high potential.

Summary: In this study, AlF3 was used as an electrolyte additive for the first time in Li-O2 batteries, which promoted the formation of a LiF@Al-Li@Al2O3-rich solid electrolyte interface (SEI) film through in-situ spontaneous reactions with Li anode in an oxygen environment. The generated SEI film contributed to inducing the homogeneous nucleation of Li, suppressing the growth of Li dendrite, and improving the cycling performance of Li anode.

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: An efficient phase inversion-impregnation approach is developed to fabricate BaO-decorated Ni8 mol% YSZ anode-supported tubular solid oxide fuel cells (SOFCs) with anti-coking properties. BaO nanoislands are successfully introduced inside the Ni-YSZ anode, leading to higher peak power densities and improved stability in methane fuel. Density functional theory calculations suggest that the loading of BaO nanoislands facilitates carbon elimination by capturing and dissociating H2O molecules to generate OH.

Summary: Li-CO2 batteries, which utilize CO2 and have a high energy density, are hindered in practical applications due to slow kinetics and safety hazards. This study introduces a stable and highly conductive ceramic-based solid electrolyte and a metal-organic framework catalyst to improve the safety and performance of Li-CO2 batteries. The optimized Li-CO2 cell shows outstanding specific capacity and cycle life, and the post-cycling analysis reveals the degradation mechanism of the electrodes. First-principles calculations based on density functional theory are also performed to understand the interactions between the catalyst and the host electrode. This research demonstrates the potential of MOF cathode catalyst for stable operation in Li-CO2 batteries.

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.
