      abstract     = {Among the diverse array of solid electrolyte options,
                      glass-ceramics hold great promise for application in
                      all-solid-state lithium batteries. In this respect, we have
                      effectively developed novel glasses and glass-ceramics
                      through an innovative approach that integrates a
                      glass-ceramic strategy with the newly introduced zinc-doped
                      Nasicon phase. This was achieved by applying melt-quenching
                      techniques coupled with meticulous control over the
                      crystallization process, guided by a thorough study of
                      crystallization kinetics. The crystallization kinetics have
                      unveiled a two-dimensional nucleation mechanism with an
                      activation energy of 165 kJ.mol-1. X-ray diffraction (XRD)
                      analysis revealed the emergence of a novel Zn-doped Nasicon
                      phase, identified as Li1.6Zn0.3Ti1.7(PO4)3, within the
                      30Li2O-20ZnO-20TiO2-30P2O5 glass-ceramic, a validation
                      corroborated through Rietveld refinement. Indeed, FT-IR,
                      Raman, and NMR analyses confirmed the formation of
                      Li1+2xZnxTi2-x(PO4)3 Nasicon phase within the glass-ceramics
                      structures. Moreover, SEM images, complemented by TEM
                      observations and density assessments, provide evidence for
                      the creation of a dense, pore-free glass-ceramic with a
                      striped microstructure. The 30Li2O-20ZnO-20TiO2-30P2O5
                      glass-ceramic demonstrates outstanding chemical durability
                      and robust mechanical properties. Notably, it exhibits high
                      total ionic conductivity, reaching 7.14.10-4 Ω-1.cm-1 at
                      room temperature, while displaying low electronic
                      conductivity of 8.10-9 Ω-1.cm-1, aligning with findings
                      from UV-visible spectroscopy. Additionally, the lithium
                      transference number is confirmed to be 0.99, positioning the
                      developed glass-ceramic as a highly competitive solid
                      electrolyte in the field of energy storage. DFT calculations
                      were conducted on the crystallized Li1.6Zn0.3Ti1.7(PO4)3
                      NASICON phase to gain detailed insights into its
                      thermodynamic stability and electronic properties.},
