Summary: This study demonstrates a feasible approach to enhance the stability of high-Ni layered oxide cathodes by immobilizing surface oxygen with yttrium and stabilizing bulk oxygen with aluminum. The stabilized oxygen framework reduces structure deterioration, parasitic reactions, and potential polarization during battery operation, leading to high reversible capacity, impressive cycle ability, and improved thermal stability. The synergistic effect of yttrium and aluminum, with strong oxygen affinities, raises the energy barrier for oxygen evolution and contributes to the enhanced electrochemical performance of high-Ni oxide cathodes.

Summary: By employing thermal-induced in situ polymerization of lithium perfluoropinacolatoaluminate, a novel interface-compatible and safe single-ion conductive 3D polymer electrolyte (3D-SIPE-LiFPA) has been developed. It is demonstrated that 3D-SIPE-LiFPA promotes the formation of a protective electrode/electrolyte interface and inhibits the dissolution-migration-deposition of transition metals. 3D-SIPE-LiFPA significantly enhances the cycle life and safety of NCM811/Li LMBs.

Summary: A structure-driven degradation mechanism is proposed for Ni-rich layered cathode material NMC811, in which a proportion of the material exhibits a lowered accessible state of charge and becomes fatigued after repetitive cycling. This degradation is attributed to high interfacial lattice strain between the reconstructed surface and the bulk layered structure above a distinct threshold.

Summary: This work introduces two novel measurement methods for capturing the thermal behaviour of Li-ion cells in the frequency domain, which are validated by comparing them to the state of the art method. All experiments are conducted with a cylindrical 18650 LFP-Graphite cell and lead to similar thermal impedance spectra. A 0-D thermal model fitted to the respective measurement results is validated with a thermal step response in the time domain, showing accurate representation of the thermal behaviour with a mean absolute error below 0.3 K. The spider-web diagram classifies and compares the methods based on five values, demonstrating a 62% reduction in the state of the art thermal measurement time and an increase in impedance measurement resolution by measuring multiple frequencies simultaneously.

Summary: Maintaining the integrity of the electrode-electrolyte interface is crucial for achieving longer cycle lives in solid-state batteries (SSBs). In this study, organic electrolyte additives are used in the cathode electrolyte interphase (CEI) layer to mitigate chemical and mechanical degradation in sulfide-based SSBs. The CEI layer derived from lithium difluorobis(oxalato)phosphate (LiDFBOP) exhibits dual functions by retarding chemical degradation at high charging potential and maintaining physical contact at low stack pressure. This research provides new perspectives and strategies for designing cathode coating materials in sulfide-based SSBs.
