(a–c) SEM images of the cross-section of samples prepared using V2O5 nanofibre dispersions of different concentrations, specifically (a) 3.5 mg/ml (sample V2O5-1), (b) 7.6 mg/ml (sample V2O5-2), and (c) 14.5 mg/ml (sample V2O5-3). (d–f) Higher resolution SEM images of the joint between a lamella and pillars of the corresponding samples.
