However, we found that the two routes resulted in surprisingly different cell performance. First, cycle1 charge and cycle2 discharge capacities via route B were 393 and 273 mAh g -1 , respectively, at 20 mA g -1 , being close to the corresponding capacity via route A (318 and 279 mAh g -1 ). It is not difficult to understand cycle1 charge capacity being close, as the two routes underwent the same deep discharge process during the 1 st cycle. However, the similar cycle2
