Energy storage technologies are critical for sustainable development, with electrolyte materials playing a decisive role in performance and safety. Single-ion conducting polymers (SICPs) represent a distinct materials class characterized by selective ion transport through immobilized ionic groups. While their potential for battery applications is recognized, an analysis of their sustainability implications and pathways to practical implementation has been lacking.

The rational tailoring and molecular-level engineering of stable cathode-electrolyte interphases (CEIs) is paramount to advancing the performance of next-generation high-energy, layered nickel-rich oxide-based lithium metal batteries. However, developing well-tailored electrolyte additives with rationally controlled interfacial chemistry remains highly challenging. Here, two lithium borates: lithium (2-methoxy-15-crown-5)trifluoroborate (C-LiMCFB) and lithium (15-methoxy-2,5,8,11,14-pentaoxahexadecan)trifluoroborate (L-LiMCFB), incorporating cyclic 15-crown-5 (15C5) and linear pentaethylene glycol monomethyl ether (PEGME) as respective host groups tethered to the boron center are designed and synthesized.

To design new nonlinear optical (NLO) crystals efficiently, mixing two or more types of functional groups is a favored strategy. Herein, by combining two types of planar π-conjugate groups, triangular (BO) and square (CO), the new lithium borate-squarate composite NLO crystal Li(CO)(HBO)(HO)·HBO was synthesized, featuring a layered structure. This crystal exhibits a moderate second harmonic generation (SHG) response of 1.

Lithium borate and aluminate salts bearing a hexafluoroisopropoxy ligand have been prepared and investigated for use in lithium-ion batteries and Cu‖Li cells. Lithium aluminate salts have poorer air tolerance but Li[Al(hfip)] resulted in superior battery cycling, with lower overpotentials for plating and stripping in Cu‖Li cells.

Lithium-ion conducting borate glasses are suitable for solid-state batteries as an interfacial material between a crystalline electrolyte and an electrode, thanks to their superior formability. Chlorine has been known to improve the electron conductivity of borate glasses as a secondary anion. To examine the impact of chlorine on lithium dynamics, molecular dynamics (MD) simulations were performed with a machine-learning interatomic potential (MLIP).
