Summary: Bimetallic sulfide SnS/Fe7S8 nanoparticles were embedded in three-dimensional N, S co-doped carbon nano-sheets (SnS/Fe7S8/NS-CNs composite) via a simple method. The SnS/Fe7S8/NS-CNs composite displayed excellent cycle and rate performance as the anode material for sodium-ion batteries (SIBs), with a high first discharge/charge capacity of 873/559.2 mAh g-1 at 0.2 A g-1 and a high maintained capacity of 305.2 mAh g-1 after long cycle (over 2000 cycles) at 1.0 A g-1. The outstanding electrochemical properties of the SnS/Fe7S8/NS-CNs electrode were attributed to the bimetallic sulfide heterostructure that enhanced electron/Na+ transfer kinetics and the 3D carbon matrix with dense carbon nanosheets that prevented SnS/Fe7S8 particle breaking. The electrochemical conductivity was also improved by the N, S co-doped 3D carbon nanosheet matrix.

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.
