Summary: This study investigates the fading of graphite anode at low temperature from the perspective of Li+ storage mechanism. It is found that the amorphous hard carbon (HC) electrode exhibits higher lithiation capacity than graphite and mesocarbon microbead (MCMB) electrodes at -20 degrees C, primarily due to the surface-induced capacitive storage mechanism. This work highlights the potential of utilizing surface-induced capacitive storage mechanism to improve low temperature electrochemical performance.

Summary: Silicon (Si) has the potential to replace graphite in next-generation lithium-ion batteries (LIBs) due to its high specific capacity, abundant reserve, and low cost. However, the poor rate performance and short lifespan of Si anodes are still major challenges due to the unstable electrode/electrolyte interface and low ion/electron conductivity. In this study, a mixed ion/electron conducting interlayer (MIECI) consisting of LiF and Li-Mg alloy is formed in situ from an intermediate MgF2 layer to stabilize the electrode/electrolyte interface. The p-Si@MgF2 anode with the MIECI shows excellent cycling stability and superior rate capacity, demonstrating the potential of this interfacial modification and engineering strategy for Si anodes in LIBs.

Summary: The sluggish evolution of lithium ions' solvation sheath can lead to dendrite formation and capacity loss in lithium batteries, especially at low temperatures. However, by using an ion-dipole strategy to regulate the fluorination degree of solvating agents, it is possible to accelerate the evolution of Li+ solvation sheath and improve battery performance. The DFEC-based electrolyte demonstrates significantly faster ion desolvation rate at low temperatures, allowing for better capacity retention in LiNi0.8Co0.1Mn0.1O2||lithium cells after cycling. This work provides a new technique towards rational design of electrolyte engineering for low-temperature lithium batteries.

Summary: This study investigates the performance of unsupported IrO2 electrocatalysts with different particle sizes synthesized by the modified Adams method in the oxygen evolution reaction (OER) and as anode electrodes for proton exchange membrane (PEM) water electrolyzers. The synthesized electrocatalysts are characterized using X-ray diffraction, Brunauer-Emmett-Teller surface area measurement, high-resolution transmission electron microscopy, and X-ray photoelectron spectroscopy. The electrochemical performance is evaluated using cyclic voltammetry and linear sweep voltammetry, and the materials are further evaluated as anode electrodes in a typical electrolytic cell. The results show that the IrO2 electrocatalyst calcined at 400°C exhibits high crystallinity, a small particle size (1.24 nm), a high specific surface area (185 m(2) g(-1)), and a high activity (177 mA cm(-2) at 1.8 V) for PEM water electrolysis.
