Summary: A functional polypropylene (PP) separator with a Li-based metal-organic framework (Li-MOF) coating is developed to regulate ion transportation and suppress the formation and growth of Li dendrites. The Li-MOF coating features a double-walled three-dimensional (3D) structure with well-defined intrinsic nanochannels and promotes homogeneous Li+ flux at the surface of Li metal. The Li-MOF coating layer also helps to build a solid-electrolyte interphase (SEI) layer that inhibits dendrites growth, resulting in highly stable Li plating/stripping cycling and high-performance lithium metal cells.

Summary: This study demonstrates the use of operando synchrotron X-ray diffraction (XRD) to directly characterize Li metal in standard batteries. By designing appropriately configured experiments, the stripping and plating of Li metal can be effectively quantified during battery cycling. The findings show that local variations in the deposition and stripping of Li metal can be probed, and the rate of Li usage can be tracked with sufficient spatial and time resolution. The results challenge the conventional wisdom that the greatest challenges in Li metal batteries are associated with Li deposition.

Summary: This study analyzed the aging effects of 450 mAh pouch cells containing 15 wt% Si after four years of storage at 21 degrees C. The results showed that severe losses of Si capacity occurred when cells were stored at high states of charge, but not when cells were fully discharged prior to storage. In addition, impedance rise was significantly higher when cells were kept at high states of charge, mainly due to phenomena taking place at the cathode.

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.
