Summary: This study reveals the degradation mechanisms of black phosphorus (BP) alkali-ion battery anodes through operando electrochemical atomic force microscopy (EC-AFM) and ex situ spectroscopy. It is found that BP wrinkles and deforms during intercalation, and undergoes complete structural breakdown upon alloying. The solid electrolyte interphase (SEI) is also unstable and tends to nucleate at defects, but disintegrates upon desodiation.

Summary: Considering the safety risks of conventional liquid organic electrolytes, researchers have turned their attention to the development of safer solid-state alternatives, such as ionic liquid-containing ionogels. By immobilizing a zwitterionic surfactant on the surface of a polymeric matrix, this study successfully enhanced the lithium-ion conductivity of the ionogels, leading to improved performance in lithium iron phosphate half-cell tests. The best rate capability (116.8 mAh g(-1) at 1 C) and cycling performance (initial discharge capacity = 148.9 mAh g(-1), capacity fading rate = 0.069% per cycle) were achieved with a surfactant loading of only 2 wt%. This research paves the way for the design of high-performance zwitterion-containing ionogel electrolytes as safer and leak-resistant alternatives to conventional liquid organic electrolytes for lithium secondary batteries.

Summary: With the increasing demand for electrochemical energy storage, commercial lithium-ion and metal battery systems have been developed. The separator, an essential component of batteries, plays a crucial role in determining their electrochemical performance. However, conventional polymer separators have limitations that hinder the development of electric vehicle power batteries. Advanced graphene-based materials have emerged as a solution to these challenges. Incorporating advanced graphene-based materials into the separator of batteries can overcome these issues and enhance their capacity, stability, and safety. This review provides an overview of the preparation and applications of graphene-based materials in different types of batteries, and outlines future research directions in this field.

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.
