Summary: Solid-state lithium metal batteries (SSLMBs) are an ideal future energy source due to their enhanced safety and energy density. Poly(ethylene oxide) (PEO)-based network solid polymer electrolytes (SPEs) have attracted attention for their low cost and good device performance. However, they face an issue of low anodic stability. Through the introduction of an interpenetrating network (IPN) consisting of PEO-based SPE and PAN secondary network, the oxidative stability was significantly increased, allowing SSLMBs to achieve high capacity and excellent cycling stability.

Summary: Compared to widely used lithium-ion batteries (LIBs) with flammable carbonate-based organic liquid electrolytes, lithium metal batteries (LMBs) with solid-state electrolyte combinations are considered as one of the ultimate schemes to replace traditional LIBs. However, solid polymer electrolytes or ceramic-polymer hybrid solid electrolytes fail to meet the flame retardancy requirement for constructing safe battery systems. This review article summarizes the four integral parts (polymer regulation, additive modification, and preparation methods) that can improve the thermal stability and high-temperature operating abilities of polymer-based solid electrolytes in LMBs.

Summary: Structural batteries are multifunctional devices that store energy and carry mechanical load. This study explores the interaction between lithium and carbon fibers in polyacrylonitrile-based carbon fibers using Auger electron spectroscopy (AES). The distribution of lithium in the fiber is found to be influenced by charge/discharge rates, with slow rates resulting in uniform distribution and fast rates leading to lithium trapping in the fiber core. This research provides insights that can improve the performance of structural batteries and guide AES analysis of carbonaceous electrode materials.

Summary: By regulating the redox state of the PVDF-b-PTFE (PVT) solid polymer electrolyte and introducing CuPcLi metal, the composition of the solid electrolyte interphase (SEI) in solid-state lithium-metal batteries is improved, leading to enhanced Li-ion transport kinetics and stable lithium plating/stripping performance. The chemisorption between Cu2+ and TFSI- restrains anion movement, while CuPcLi improves lithium ion release, resulting in high lithium-ion conductivity and transference number. The PVT-10CuPcLi solid polymer electrolyte paired with LiFePO4 and NCM622 cathode exhibits excellent cyclic performance with high capacity retention.

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: 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.
