Although the underlying mechanism is debatable, studies have begun to reveal that the non-zero electronic conductivity of solid electrolyte can promote lithium nucleation both in the bulk and at the grain boundary of the electrolyte 12, 21, 22, 23.
The commercialization of lithium batteries has been expedited by advancements in anode materials , , , . Notably, energy density remains a pivotal factor in the development and utilization of lithium batteries.
The high capacity of this cathode also implies that lithium metal as thick as 32 μm could be reversibly deposited and stripped through the tailored Ta–LLZO solid electrolyte over 100 times without any notable degradation. The cells were also tested under harsher conditions, such as a high temperature of 100 °C (Fig. 3e, f).
The observations of inductively coupled plasma atomic emission spectroscopy (ICP-AES), Raman spectroscopy, and neutron diffraction (ND) measurements thoroughly proved that the cubic phase can be stabilized at lithium contents ~7 for C Zr–Hf–Sc–Nb and C Zr–Hf–Sn–Sc–Ta.
The high Li2 (96h) site occupancy of C Zr–Hf–Sn–Sc–Ta exceeded that of the vacancy-driven garnet (Li = 6.5, Li2 occupancy = 0.375, corresponding to 4.5 lithium per the formula unit) reported in the literature 24, indicating that the lithium contents of C Zr–Hf–Sn–Sc–Ta is ~7.
Comparing these results with those for the cells composed of the pristine doped-LLZO electrolytes in Supplementary Fig. 25 strongly supports the hypothesis that lithium penetration in the protonated Ta– and Al–LLZO electrolytes is significantly suppressed, which allows operation at a practically high current density.
