XRD patterns of LTO and LTO/C.
(a) As-prepared LTO. (b) LTO after soaking under Condition A (DEC at 50°C). (c) LTO after soaking under Condition B (1 MLiPF6/EC+DMC+EMC at 50°C). (d) LTO in fully charged NCM/LTO battery stored under Condition D. (e) LTO in NCM/LTO battery cycled under Condition E. (f) As-prepared LTO/C. (g) LTO/C in fully charged NCM/(LTO/C) battery stored under Condition D. (h) LTO/C in NCM/(LTO/C) battery cycled under Condition E. Note that the NCM/LTO and NCM/(LTO/C) batteries tested under Conditions D and E were fully discharged before the XRD analysis.
