Tubular MoO2 organized by 2D assemblies for fast and durable alkali-ion storage

Excellent durability over 10 000 cycles and high rate capability could be achieved in hierarchical MoO2 architecture for multifunctional alkali-ion storage. The greatly enhanced charge storage is attributed to the significant pseudocapacitance contributions. This study reveals a broad potential of MoO2 in electrochemical energy storage.116
