Summary: In this paper, an algorithm based on loop current detection is proposed to detect internal short circuit of Li-ion batteries, enabling real-time sensing of internal short circuit in a multi-series 2-parallel battery module. The method only requires voltage detection at both ends of the diagnostic resistor, minimizing detection points and additional wiring. Experimental results show that the method is effective in timely detecting internal short circuits in parallel lithium-ion battery packs.

Summary: This paper proposes an active protection method based on the evaluation of internal short circuit (ISC) risk. An evaluation model based on the electrochemical model is established and successfully verified with experimental data.

Summary: Lithium metal materials are promising anodes for high energy density batteries, but the biggest challenge for their engineering application is the safety concern. Understanding the internal short circuit (ISC) behaviors of lithium metal batteries (LMBs) under mechanical abusive loading is essential before commercialization. This study characterizes the mechanical behaviors of LMB components, establishes a physics-based model, and reveals the ISC process from mechanical deformation to triggering. The effects of factors like state-of-charge and cycle numbers on ISC behaviors are also studied.

Summary: In this study, a coupled multi-physics model is established to describe the mechanical, electrical, and thermal response of lithium-ion batteries (LIBs) under dynamic loading. Four internal short circuit (ISC) modes are revealed through disassembling the LIBs after dynamic loading, and a strain-based ISC criterion is proposed. The mechanical-electrical-thermal behavior of LIBs in quasi-static and dynamic loading is compared and analyzed. The triggering impact energy of four ISC modes for LIBs with different SOCs is concluded.

Summary: This study investigated the thermal runaway mechanism of lithium ion pouch cells through nail penetration experiments, finding that cells with higher state of charge and penetrated by larger nails are more prone to thermal runaway.

Summary: This article proposes a fault diagnosis method for the early detection and assessment of soft internal short-circuit faults in lithium-ion battery packs, ensuring the safe operation of electric vehicles. Fault features are extracted from the data using the incremental capacity curve, making them easier to identify than small voltage differences. The local outlier factor method is then used to detect the early soft internal short-circuit fault by calculating the local outlier factor value of each cell within the battery pack.

Summary: In this study, a time-saving approach for measuring the open-circuit voltage (OCV) of a battery is proposed. By using a simplified first-order RC circuit model, the OCV at each state of charge (SOC) can be computed without the need for complete voltage relaxation information. Experimental results demonstrate that this approach significantly reduces the measurement time (usually less than 6 minutes) while maintaining high accuracy (usually less than 3 mV) compared to traditional methods.

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.
