      abstract     = {Advancing energy density, enabling lithium metal anodes,
                      and ensuring unparalleled safety and operational reliability
                      in lithium batteries hinge on advancing inorganic
                      solid-state electrolytes. To overcome current im-pediments,
                      we present an innovative approach that integrates
                      glass-ceramics with a pioneering new Nasicon strategy
                      involving molybdenum doping. In the conducted study, a
                      series of 14Li2O-9Al2O3-38TiO2-(39-x)P2O5- xMoO3 glasses,
                      denoted as LATPMox, along with their corresponding
                      glass-ceramics (LATPMox-GC), have exhibited a promising
                      characteristic as solid electrolytes. X-ray diffraction
                      (XRD) analysis confirms the formation of the novel Mo-doped
                      Nasicon phases in the glass-ceramics, as validated by
                      Rietveld refinement. Examination of the crystallization
                      kinetic behavior of the glasses reveals a three-dimensional
                      nucleation process with spherical particle growth, featuring
                      an activation energy of 165 kJ mol-1. Transmission Electron
                      Microscopy TEM char-acterization aligns crystallization
                      behavior with crystallite and distribution within the glass
                      matrix, resulting in a compact and dense microstructure. The
                      structural properties of the resultant phases are examined
                      through FT-IR, Raman spectroscopy, and TEM-SEAD analysis.
                      Vickers indentation tests were employed to assess the
                      microscopic fracture toughness, and both the glass and
                      glass-ceramics materials demonstrated favorable mechanical
                      per-formance. Optical characterization using UV–visible
                      absorption highlights the reduction of Mo6+ to Mo5+, likely
                      occupying tetrahedral sites within the crystalline lattice.
                      Impedance spectroscopy measurement showcases the effective
                      promotion of ionic conductivity following Mo doping,
                      reaching a total conductivity value of 5.50 × 10-5 Ω-1
                      cm-1 along with a high lithium transference number of 0.99
                      at room temperature for LATPMo2.6-GC glass-ceramic. This
                      value is larger than that of many other glass-ceramics as
                      well as that of the well-known lithium phosphorous
                      oxy-nitride LiPON solid electrolyte whose ionic conductivity
                      at RT is around 2 × 10-6 Ω-1 cm-1.},
