Summary: The crossover of transition-metal ions has minimal effect on the lithium-metal anode in batteries with high-nickel layered-oxide cathodes, but the soluble decomposition products from the anode adversely impact the cathode, accelerating impedance growth and capacity fade. This study highlights the importance of improved battery design for lithium-metal anodes to address these crossover effects.

Summary: A modified etching strategy combined with a sol-gel method was used to prepare microscale porous silicon microspheres encapsulated with an inner amorphous carbon shell and an outer titanium oxide shell. The interconnected pores accommodate the expansion of the silicon core during lithiation and the double shells enhance the kinetic behavior and maintain the structural integrity. The resulting anodes show high specific capacity, excellent rate capability, stable solid-electrolyte interphase films, and steady mechanical structure.

Summary: The metalation of carbazole with magnesium in THF leads to the formation of sparingly soluble Hauser base, which shows good cyclability and low over-potential in electrodeposition/stripping of magnesium on a copper current collector. Improved performance is achieved with the turbo-Hauser bases, which exhibit significantly higher solubility in ethereal solvents. Solvation energies in THF increase from (thf)(x)MgBr2 to (thf)(x)Mg(Carb)(2) for an equal number x of ligated THF molecules.

Summary: Silicon is a promising replacement for graphite as an anode material due to its high capacity, but its volume changes during lithiation can lead to capacity fade. This study investigates the expansion behavior of silicon-based cells using dilatometry. The results show irregular thickness changes in the cells, with the maximum thickness occurring during discharge, not at full charge. The hysteresis is attributed to cathode expansion rather than anode contraction.

Summary: In this study, iron hexacyanoferrate nanoparticles were synthesized using a microwave-assisted co-precipitation method, showing a specific capacity of 120 mAh g(-1) and a capacity retention of 84.8% over 100 cycles at 20 mA g(-1) current, as well as a capacity of 80 mAh g(-1) at 10 C rate. Ex-situ X-ray absorption spectroscopy (XAS) revealed some irreversibility and changes in Fe-C and Fe-N bond lengths during the initial charge/discharge cycle, which were attributed to electrode activation processes and partly explained the observed capacity fading.

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: 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.
