Summary: This study investigates the application of Prussian blue analogues (PBAs) as electrode materials for aqueous ammonium ion batteries (AAIBs). A PANI/Na0.73Ni[Fe(CN)(6)](0.88) hybrid (PNFF) is synthesized using a covalent bond assisted engineering with in situ polyaniline (PANI) polymerization, combining the high conductivity of PANI and the stability of PBAs. It is found that the PANI content affects the electrochemical performance of PNFF, and an optimized PANI content results in enhanced reversible capacity and cycling stability. The ammonium storage mechanism of PNFF is investigated using in situ Raman and ex situ XPS/FTIR analysis, and a durable aqueous NH4+ full cell is assembled using a polyimide@MXene anode.

Summary: Lithium-ion batteries (LIBs) are crucial for the electric vehicle (EV) industry, and LiNi1-x-yCoxMnyO2 (NCM) is the dominant cathode material used in EV LIBs. Due to the need for increased driving range, Ni content in NCM is maximized, but the resulting Ni-rich NCM is unstable. Doping with foreign elements has been explored as a strategy to overcome this instability, with over 46 elements considered and their effects on LIB performance investigated in numerous research articles. This comprehensive analysis of various doping elements and their impact on LIB performance provides valuable insights for the LIB industry and academia.

Summary: Cobalt disulfide (CoS2) is a promising candidate for sodium ion batteries, but its low conductivity and volume change pose challenges to its large-scale application. In this study, reduced graphene oxide (rGO) is introduced to improve the conductivity and inhibit volume change of CoS2 through the construction of a conductive network. A balanced strategy based on the bucket principle is proposed to enhance the rate capability and cycling performance. The optimized CoS2/rGO electrode exhibits excellent performance in terms of capacity and retention, attributed to improved charge transfer and volume change accommodation provided by the rGO conductive network.

Summary: High-capacity electrochemical energy storage systems are urgently needed for electric vehicles and smart grids. Developing electrode materials with low molecular weights is the most efficient way to increase capacity. Metal halides are theoretically ideal cathode materials, but their rechargeability is hindered by their cubic structure and large energy barrier. By reducing their dimensionality with reduced graphene oxide (rGO), reversibility is achieved for potassium halides, lithium halides, sodium halides, and zinc halides. Metal halides-based electrode materials show promising application prospects and deserve further research.

Summary: An advanced Li-sphere with a regular morphology is able to achieve high-efficiency long-term cycles in Li metal anode due to its well-defined structure and superior solid-electrolyte interphase (SEI). The presence of high Li+ cluster-like solvation sheaths in a high-concentration NO3-(LH-LiNO3) electrolyte explains the deposition of advanced Li spheres. The structural evolution of Li-sphere deposits during nucleation and growth involves a critical amorphous-crystalline phase transition. The Li-sphere anode exhibits stable structural engineering, suppressing Li dendrite growth and demonstrating a long life of 4000 cycles in symmetrical cells at 2 mA cm(-2). In addition, the Li-sphere anode also exhibits a robust dendrite-free structure, achieving a high capacity retention of 90.5% after 1000 cycles in combination with a LiFePO4 (LFP) 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.
