Summary: The necessity of a feasible process for recycling lithium-ion batteries is evident due to high demand for raw materials and regulatory requirements. In this study, a selective recovery of lithium using oxalic acid was investigated. Optimal parameters of 60°C, 60 min, and 0.6 M oxalic acid resulted in a 98.8% yield for lithium, while cobalt, nickel, and manganese had minimal leaching. This method can significantly improve lithium recovery in current recycling processes, with the added advantage of complete dissolution of aluminum.

Summary: Electric vehicles powered by Li-ion batteries can be dangerous due to the flammable liquid electrolytes, but all-solid-state batteries offer a safe alternative. This study demonstrates that B-doping and coating of a Ni-rich Li[Ni0.9Co0.05Mn0.05]-O2 cathode can enhance the microstructure and cathode-solid electrolyte interface, resulting in an all-solid-state battery that cycles stably for 300 cycles with minimal capacity fading. The B-doped, B-coated Li[Ni0.9Co0.05Mn0.05]O2 cathode achieves a discharge capacity of 214 mAh g-1, one of the highest among all-solid-state batteries, and retains 91% of its initial capacity after 300 cycles, surpassing previously reported all-solid-state batteries in terms of energy density without compromising cycling stability.

Summary: Seawater batteries (SWBs) have attracted significant interest in the field of electrochemical energy storage due to their low cost, abundance, and potential for long-duration energy storage. However, their practical application is hindered by poor electrochemical performance related to inadequate interfaces of the solid electrolyte (SE), as well as structural and chemical instabilities and slow ionic transport properties. This study focuses on improving the performance of a surrogate SWB by introducing tailored dopants into the Na3Zr2Si2PO12 (NZSP) solid electrolyte membrane and observing the resulting changes in surface chemistry, local structure, ionic conductivity, and critical current density. The doped NZSP exhibits a more densely packed pellet with a uniformly distributed porous structure, demonstrating enhanced cycling stability and reversible capacities based on different sodium storage mechanisms.

Summary: The development of thin, dense, defect-free solid electrolyte films is crucial for practical and commercial solid-state batteries. This study demonstrates a simple processing route for antiperovskite (Li2OHCl) solid electrolyte materials, which can produce films/pellets with very high densities (around 100%) and higher conductivities compared to conventional pressed pellets. The new protocol also improves the critical current density and lithiophilicity of the material through surface nitrogen enrichment. Distribution of relaxation time analysis confirms the faster transport mechanisms in the antiperovskite films/pellets produced using the new pathway. Overall, these findings highlight the feasibility of engineering antiperovskite solid electrolytes at the grain scale as a highly desirable approach for practical all-solid-state batteries.

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.

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.
