Summary: In this study, twin boundaries (TBs) were quantitatively estimated and characterized using advanced electron microscopy. It was further validated that TBs can initiate massive cracks during electrochemical cycling, leading to performance decay of LiNiO2. While adjusting synthesis conditions cannot avoid TB formation, it was found that a coprecipitation method can effectively eliminate TBs, resulting in improved cycling stability of LiNiO2. The coprecipitation method was also used to synthesize TB-free LiCoO2, demonstrating improved cycling stability.

Summary: This paper focuses on improving the electrochemical performance of Sodium Vanadium Oxyfluorophosphate (NVPFO), a high-stability, high-capacity, and high-voltage cathode material for sodium-ion batteries, by doping it with Zr4+ ions. A series of Na3V2-xZrx(PO4)2F2O compounds are prepared, and the successful doping of Zr4+ is confirmed through various characterization techniques. The optimal doping concentration of 4 at% results in Na3V1.96Zr0.04(PO4)2F2O, which exhibits a specific capacity of 128, 106, 85, and 55 mA h g-1 at different current rates. Additionally, the doped material shows improved cycling stability and a higher Na+ diffusion coefficient compared to the undoped NVPFO.

Summary: In this study, we used electrophoretic NMR (eNMR) measurements and molecular dynamics (MD) simulations to examine the electric-field-induced transport in a concentrated solution of LiPF6 salt dissolved in an ethylene carbonate/ethyl methyl carbonate (EC/EMC) mixture. It was found that ethylene carbonate (EC) exhibited selective transport compared to ethyl methyl carbonate (EMC) due to its preferential solvation of cations and its dynamic consequences. Molecular simulations also revealed the presence of various transient solvent-containing clusters migrating at different velocities. This study highlights the importance of considering the presence of four species in mixed-solvent electrolytes.

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.

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.
