Li-based all-solid-state batteries (ASSBs) are considered feasible candidates for the development of next generation high-energy rechargeable batteries. However, ASSBs detrimentally affected by a limited rate capability and inadequate performance at high currents. To circumvent these issues, here we propose use Nb1.60Ti0.32W0.08O5-δ (NTWO) as negative electrode active material. NTWO is capable overcoming limitation lithium metal electrode, offering fast-charging capabilities cycle stability. Physicochemical electrochemical characterizations in combination with Li6PS5Cl (LPSCl) solid-state electrolyte demonstrate that formation LiWS2 electrode|electrolyte interphase main responsible improved battery performance. Indeed, when an NTWO-based LPSCl coupled LiNbO3-coated LiNi0.8Mn0.1Co0.1O2-based positive lab-scale cell maintaining 80% discharge capacity retention after 5000 cycles 45 mA cm−2 60 °C MPa.
