Summary: Polymer based quasi-solid-state electrolyte (QSE) has attracted attention for its high safety in rechargeable batteries, but low ionic conductivity and solid-electrolyte-interface (SEI) layer have been an issue. This work demonstrates the ordered and fast transport of lithium ions (Li+) in QSE, significantly increasing its ionic conductivity to 3.69 mS cm(-1). The QSE also induces in situ and uniform generation of Li3N and LiNxOy in SEI, leading to excellent stability in Li||NCM811 batteries and LiFePO4 LMBs.

Summary: By regulating the redox state of the PVDF-b-PTFE (PVT) solid polymer electrolyte and introducing CuPcLi metal, the composition of the solid electrolyte interphase (SEI) in solid-state lithium-metal batteries is improved, leading to enhanced Li-ion transport kinetics and stable lithium plating/stripping performance. The chemisorption between Cu2+ and TFSI- restrains anion movement, while CuPcLi improves lithium ion release, resulting in high lithium-ion conductivity and transference number. The PVT-10CuPcLi solid polymer electrolyte paired with LiFePO4 and NCM622 cathode exhibits excellent cyclic performance with high capacity retention.

Summary: The next generation of lithium batteries requires high energy density, which can be achieved by shifting from conventional intercalation-based anode (such as graphite) to lithium metal anode. However, the highly reactive nature of Li metal and the hostless deposition and stripping reactions hinder its practical use as an anode. The solid electrolyte interphase (SEI) plays a vital role in protecting the Li metal surface, but the SEI layers formed in different electrolyte systems have distinct properties, leading to different interfacial issues. This report compares the interfacial issues and provides different strategies for SEI modification to overcome these challenges.

Summary: Amino acids are bio-building blocks that play various roles in metabolic activities. Supramolecular structures formed by amino acids exhibit amyloid-like characteristics, which are driven by hydrogen bonds and play critical roles in the properties and applications of amino acid assemblies. Tyrosine-based superstructures have diverse properties and functions, making them promising next-generation biomaterials for biomedical applications. However, modulating the energetically stable supramolecular structures of tyrosine-based organizations is challenging. By assembling L-Y and D-Y, the secondary structures of the supramolecular assemblies can be modulated, leading to distinct organization kinetics and modulation of physicochemical properties.
