Summary: The ice-templating approach is a popular method for preparing macroporous monoliths, offering environmental friendliness and low cost. Through a directional freezing process, aligned ice crystals are formed, resulting in a new material genre called aligned macroporous monoliths (AMMs). This review provides an overview of the IT technique and the preparation of AMMs, focusing on two representative AMMs: aligned micro-honeycomb monoliths and aligned microlamellar monoliths. The structural anisotropy and regularity of these AMMs make them suitable for various applications, such as thermal insulation, filtration, energy storage, and structural engineering. The future directions in this research field are also discussed.

Summary: Lithium-oxygen batteries (LOBs) are a promising option for rechargeable batteries with high theoretical energy densities. The optimization of the carbon-based positive electrode is crucial for the practical implementation of LOB technologies. In this study, carbon gel-based self-standing membranes were prepared as positive electrodes and their performances in LOBs were evaluated under lean-electrolyte, high-areal-capacity conditions. The results indicated that nanometer-sized pores had limited effects on cycle performance but contributed to enhancing discharge capacity; macro-sized pores had a positive effect on enhancing discharge capacity; crystallinity and surface functional groups influenced discharge potential and cycle life. This study highlights the importance of controlling the physicochemical properties of porous carbon-based positive electrodes for achieving LOBs with high energy densities and extended cycle lives.

Summary: Controlling the characteristics of Li2O2 deposition during discharging in lithium-air batteries (LABs) can reduce the overpotential required for charging, therefore improving the cycle performance of LABs. The presence of functional groups in the cathode carbon affects the deposition of Li2O2 and the performance of LABs. By increasing the number of oxygen-containing functional groups (OCFGs) in carbon gels, the deposition of Li2O2 within the mesopores of carbon particles can be increased, leading to a reduction in charging overpotential. However, a large number of OCFGs can cause side reactions that deteriorate cycle performance, which can be mitigated by heat treatment.

Summary: In this study, the effects of functional groups in the cathode carbon on the characteristics of Li2O2 and the performance of lithium-air batteries were investigated. It was found that increasing the number of oxygen-containing functional groups (OCFGs) through acid treatment can increase the deposition of Li2O2 within the mesopores of carbon particles, leading to a reduction in charging overpotential. However, CGs with a large number of OCFGs tend to undergo side reactions that deteriorate cycle performance, which can be mitigated by removing carboxyl groups through heat treatment.

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.
