Lithium phosphorus oxynitride (LiPON) is a well-known amorphous thin filmsolid electrolyte that has been extensively studied in the last three decades.Despite the promises to pair with Li metal anode and various cathode materials,the presence of rigid substrate and LiPONs unique amorphous, air-sensitivenature set limitations to comprehensively understand its intrinsic propertiesfor future development and applications. This work demonstrates a methodologyto synthesize LiPON in a freestanding form that exhibits remarkable flexibilityand a Young s modulus of ~33 GPa. Solid-state nuclear magnetic resonance(ss-NMR) and differential scanning calorimetry (DSC) results with unprecedentedhigh signal-to-noise ratio could be obtained with such freestanding LiPON(FS-LiPON), revealing the Li-LiPON interface bonding environmentsquantitatively and a well-defined glass transition temperature for LiPON.Combining interfacial stress and a seeding layer, FS-LiPON demonstrates auniform and fully dense Li metal deposition without the aid of externalpressure. Such a FS-LiPON film offers new opportunities for fundamental studyof LiPON material and associated interfaces, and provides perspectives forinterface engineering in bulk solid-state battery.
