Summary: In this study, the commercially mature ion-exchange (IX) method was explored for the first time to recover lithium from spent lithium iron phosphate (LFP) cathodes. The Li-K IX reaction using oxalic acid as the feeding solution delivered a potential product of multi-elemental fertilizer. This simple and economical technology provides a practical recycling strategy for spent LFP batteries.

Summary: This paper investigates the aging behavior and mechanism of cylindrical LFP batteries by designing a cross-comparison aging test, which uses three constant current and two different dynamic working conditions for accelerated aging at high temperature. The aging behavior and mechanism are quantitatively studied through in-situ electrochemical test and ex-situ Post-Mortem methods. External characteristic parameters such as capacity, internal resistance, and open circuit voltage are periodically checked during the long-term cycle of the battery. This multiscale analytical method enables a detailed understanding of the performance loss process, guiding performance prediction and safety diagnostics.

Summary: The need to recover critical elements from lithium-ion batteries is crucial, and adapting the hydrometallurgical recycling processes is necessary due to the development of cathode materials and the search for cheaper alternatives. By optimizing the leaching process, an effective way of recovering lithium from different cathode materials has been identified.

Summary: This study investigates the thermal runaway propagation behaviors of large format lithium ion battery modules under different inclined ceilings. The results show that a larger ceiling angle provides better heat dissipation condition for the modules, and the threshold value of ceiling angle at which thermal runaway stops propagating is between 10 and 30 degrees.

Summary: A FeF3.0.33H(2)O@carbon nanocomposite with a pomegranate-like structure has been successfully synthesized, which exhibits excellent performance as a cathode material in both lithium-ion and sodium-ion batteries. The unique hierarchical carbon-coated architecture of the nanocomposite effectively reduces electrode polarization and enables high reversibility and rate performance.

Summary: Mn and K co-doped lithium iron phosphate (LFP) cathode materials were successfully synthesized by solvothermal method. The contributions of the two dopants to the LFP were investigated using density functional theory (DFT) calculations and various characterizations. The presence of Mn improved the energy band and diffusion kinetics, while K contributed to the stabilized structure and widened diffusion channel. The co-doped LFP cathode exhibited a high capacity of 145 mAhmiddotg-1 at 5 C and maintained a 96% retention rate after 400 cycles. The interaction between the two doping elements was discussed by comparing with a control group, and the KLMFP samples showed superior electrochemical performance in cyclic voltammetry (CV), electrochemical impedance spectroscopy (EIS), and charge-discharge cycling tests.

Summary: In this study, user-defined reference electrodes based on LFP were fabricated using an ultrashort pulse laser. The results showed that these electrodes have minimal impact on the cell capacity and can provide reproducible voltage output at low to moderate C-rates. They also do not affect the cell expansion during cycling.

Summary: This study investigates the highly reversible proton-coupled MnIV and MnII conversion in mild aqueous buffered electrolyte using 3D free-standing electrospun CNF electrodes as conductive scaffolds. The experimental results show that the free-standing CNF electrodes can maintain high charge capacity and cycling efficiency even at high MnO2 loading. This combination could be a striking approach for developing high energy efficiency MnO2-based mild aqueous batteries.

Summary: We consider a one-dimensional McKean-Vlasov SDE and its associated mean-field interacting particle system. The peculiarity of this system lies in the combination of interaction and reflection at the boundaries, which results in a nonlocal effect of reflection. We show the pathwise well-posedness of the McKean-Vlasov SDE and the convergence of the particle system in the limit of a large number of particles.

Summary: This paper investigates a stochastic version of Euler equations using the infinite-dimensional geometric approach. For the Euler equations on a compact manifold (possibly with smooth boundary), we establish the local existence and uniqueness of a strong solution in spaces of Sobolev mappings. Our approach combines techniques from stochastic analysis and infinite-dimensional geometry, providing a novel toolbox for establishing the local well-posedness of stochastic nonlinear partial differential equations.
