2023, Electrochimica ActaCitation Excerpt :This places strict requirements on material composition [3]. Furthermore, the main barriers to Li+ diffusion were identified to be the size of vacant sites [4], the oxygen windows acting as bottleneck between vacant sites [5, 6] and the strength of lithium and oxygen bonding [7]. One of the challenges encountered while deploying LLTO in Li-metal batteries was its instability on a contact with metallic lithium, when it undergoes easy and fast Li+ insertion with concurrent reduction of Ti4+ to Ti3+, leading to high electronic conductivity [1, 8]–[10].

2019, Renewable and Sustainable Energy ReviewsCitation Excerpt :However, the Li+ ionic conductivity and stability of this type solid oxide electrolyte are still desired to be improved more. The solid oxide electrolytes with Perovskite structure (ABO3) were firstly reported by Latie et al. [50] and later by Belous et al. [51]. In such a structure, the transition metal element (B) occupies the centre of vertex-sharing BO6 octahedra, and the high conductivity is considered to be originated from the transport of Li+ ions via the deficiencies among the A-sites in the ABO3 (Fig. 2).

2018, Solid State IonicsCitation Excerpt :To determine the parameters for the PGSE NMR measurements, 7Li T1 and T2 values are important and shown in Fig. 4. In the present temperature region, the temperature dependences of T1 and T2 were small, corresponding to near bottom of the Bloembergen-Purcell-Pound plots in the wide temperature range for the 7Li T1 of perovskite-electrolytes [5,43–46,48–51]. The T2 values were between 4 and 7 ms and not very short to measure Li+ PGSE NMR compared with those of the garnets [64].
