    Abstract

    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. Mater. 10 (2011) 682–686, https://doi.org/10.1038/nmat3066.” The authors would like to apologize for any inconvenience caused.
