Summary: A solid polymer electrolyte (SPE) based on a molecular composite of aromatic polybenzimidazole (PBI) and PEO is proposed to address the issues of low ionic conductivity and potential safety hazards in PEO-based electrolytes. The strong intermolecular interactions effectively inhibit PEO crystallization and significantly improve the modulus, strength, and ionic conductivity of the electrolyte. Additionally, thermal stability and flame retardancy are also enhanced, making the PBI/PEO electrolyte a promising candidate for safe and high-performance all-solid-state lithium ion batteries.

Summary: By exploiting the advantages of solid polymer electrolytes (SPEs) including light weight, flexibility, and flame retardancy, this study addresses the safety concerns and energy density improvement for lithium-ion batteries (LIBs). The development of SPEs is still hindered by their low ionic conductivity, which can be overcome by a hierarchical structure of flower-like Co3O4 microspheres and a multifunctional coating of polydopamine (PDA) used as a lithiophilic backbone. The interphase characterizations and their effects on Li+ conductivity and mechanical/electrochemical stability are investigated, and the potential application of Co3O4@PDA-based composite solid polymer electrolytes (CPEs) in all-solid-state LIBs is demonstrated.

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.
