      abstract     = {The solvent-free in situ polymerization technique has the
                      potential to tailor-make conformal interfaces that are
                      essential for developing durable and safe lithium metal
                      polymer batteries (LMPBs). Hence, much attention has been
                      given to the eco-friendly and rapid ultraviolet (UV)-induced
                      in situ photopolymerization process to prepare solid-state
                      polymer electrolytes. In this respect, an innovative method
                      is proposed here to overcome the challenges of UV-induced
                      photopolymerization (UV-curing) in the zones where UV-light
                      cannot penetrate, especially in LMPBs where thick electrodes
                      are used. The proposed frontal-inspired photopolymerization
                      (FIPP) process is a diverged frontal-based technique that
                      uses two classes (dual) of initiators to improve the slow
                      reaction kinetics of allyl-based monomers/oligomers by at
                      least $50\%$ compared with the conventional UV-curing
                      process. The possible reaction mechanism occurring in FIPP
                      is demonstrated using density functional theory calculations
                      and spectroscopic investigations. Indeed, the initiation
                      mechanism identified for the FIPP relies on a photochemical
                      pathway rather than an exothermic propagating front forms
                      during the UV-irradiation step as the case with the
                      classical frontal photopolymerization technique. Besides,
                      the FIPP-based in situ cell fabrication using dual
                      initiators is advantageous over both the sandwich cell
                      assembly and conventional in situ photopolymerization in
                      overcoming the limitations of mass transport and active
                      material utilization in high energy and high power LMPBs
                      that use thick electrodes. Furthermore, the LMPB cells
                      fabricated using the in situ-FIPP process with high mass
                      loading LiFePO4 electrodes (5.2 mg cm-2) demonstrate
                      higher rate capability, and a $50\%$ increase in specific
                      capacity against a sandwich cell encouraging the use of this
                      innovative process in large-scale solid-state battery
