To promote the practical application of BTMOs, their structure-performance relationship and development bottleneck should be further understood. In this review, the crystal structures and corresponding electrochemical properties of typical BTMOs in various aqueous electrolytes are introduced briefly. Some ingenious methods for improved electric conductivity, mainly including building integrated electrodes and composites, introducing oxygen vacancy and element doping are discussed carefully. Some practicable ideas for boosted cycle stability through avoiding/alleviating agglomeration, volume change and dissolution are provided in detail. Finally, the existing problems and challenges for structural and performance regulation of BTMOs are generalized. This review will support valuable information for building better supercapacitors using BTMOs.
