  1. Structural and Li-Ion Conduction Properties of Ti- and W-Substituted LiTa<sub>2</sub>PO<sub>8</sub>

    Li+-conductive oxide solid electrolytes (SEs) are chemically stable and could potentially lead to safer all-solid-state batteries. However, practical applications of oxide SEs are limited in the current stage, and one of the crucial problems arises from 1 or 2 orders lower ionic conductivity of oxide SEs than sulfide and chloride SEs. Among the various oxide SEs, LiTa2PO8 exhibits a high Li+ conductivity of 2.5 × 10-1 mS cm-1 at room temperature. Because most high Li+ conductive oxide SEs such as Li7-xLa3Zr2-xNbxO12 and Li1+xAlxTi2-x(PO4)3 have been achieved by chemical substitutions from parent compounds (Li7La3Zr2O12 and LiTi2(PO4)3), chemical substitutions for LiTa2PO8 will be an effective way for further increasing Li+ conductivity. Here, we synthesized single-phase Ti-and W-substituted LiTa2PO8 and investigated their Li+ conductivities. Both of these substitutions decreased unit cell volume. Ti-substitutions decreased activation energy for Li+ conduction in the bulk (Ea) and almost doubled both the total Li+ conductivity (σtotal) and bulk Li+ conductivity (σbulk) W-substitutions also decreased Ea, but both the σtotal and the σbulk slightly decreased. The calculated Ea of σbulk by bond valence energy assuming single-ion hopping increased in both substitutions due to their smaller unit cell volume. On the other hand, experimentally obtained Ea decreased for both substitutions. This discrepancy may arise from the ionic correlation of the Li+ ion in LiTa2PO8, providing further insight into enhancing the ionic conductivity.

    Garnet-type Li7La3Zr2O12 (LLZ) has advantages of stability with Li metal and high Li+ ionic conductivity, achieving 1 × 10-3 S cm-1, but it is prone to react with electrode active materials during the sintering process. LISICON-type Li3.5Ge0.5V0.5O4 (LGVO) has the advantage of less reactivity with the electrode active material during the sintering process, but its ionic conductivity is on the order of 10-5 S cm-1. In this study, these two solid electrolytes are combined as a multilayer solid electrolyte sheet, where 2 μm thick LGVO films are coated on LLZ sheets to utilize the advantages of these two solid electrolytes. These two solid electrolytes adhere well through Ge diffusion without significant interfacial resistance. The LLZ-LGVO multilayer is combined with a LiCoO2 positive electrode and a lithium metal anode through annealing at 700 °C. The resultant all-solid-state battery can undergo repeated charge-discharge reactions for over 100 cycles at 25 or 60 °C. The LGVO coating suppresses the increases in the resistance from the solid electrolyte and interfacial resistance induced by annealing by ca. 1/40. As with sulfide-based all-solid-state batteries, function sharing of solid electrolytes will be a promising method for developing advanced oxide-based all-solid-state batteries through a sintering process.

    The authors regret that the activation energy from a linear fitting function of DLi values was published incorrectly in the above article. The values reported in Highlight, Abstract and the sentence of line 25 in the right hand column of p. 4 are much higher than the correct one. The correct value is 0.11 eV. In addition, the reported activation energy value for total conductivity of LiTa2PO8 in reference [14] was published incorrectly. The correct reported value is 0.36 eV. Then the sentence of lines 25–28 in the right hand column of p. 4 is changed to “The activation energy was determined to be 0.11 eV from a linear fitting function of DLi values, which is much smaller than the results of the AC impedance measurements of LiTa2PO8 in this study (0.52 eV) and in the previous report (0.36 eV) [14].” The values of the apparent diffusion constant (DLi) in Fig. 7 are correct. The erratum has no effect on the conclusions of the above paper. The authors also regret that the β value in the sentence of line 15 in the right hand column of p. 1, the conductivities, temperatures for DLi values, a reference in Table 1, and title of the reference [23] were published incorrectly in the above article. The correct β value is 90.0355(3)°. The correct conductivity values σ (S cm−1) are 1.1 × 10−3 for Li6.5La3Zr1.5Ta0.5O12 [7,13], 1.3 × 10−3 for Li6.5La3Zr1.5Nb0.5O12 [9,21], 2.5 × 10−4 for LiTa2PO8 [14] and 4.8 × 10−4 for LiTa2PO8 in this study. The correct temperatures (K) for DLi are 305 for Li6.5La3Zr1.5Nb0.5O12, 298 for Li10GeP2S12 and Li7GePS8. The correct reference numbers for Li6.6La3Zr1.6Ta0.4O12 are [11,20]. The correct reference [23] is “N. Kamaya, K. Homma, Y. Yamakawa, M. Hirayama, R. Kanno, M. Yonemura, T. Kamiyama, Y. Kato, S. Hama, K. Kawamoto, A. Mitsui, A lithium superionic conductor, Nat.
