Abstract Recently, a new class of 2D materials, i.e., transition metal carbides, nitrides, and carbonitrides known as MXenes, is unveiled with more than 20 types reported one after another. Since they are flexible conductive, MXenes expected to compete graphene other materials in many applications. Here, general route simple self‐assembly oxide (TMO) nanostructures, including TiO 2 nanorods SnO nanowires, on MXene (Ti 3 C ) nanosheets through van der Waals interactions. The nanosheets,...
Abstract Hard carbons (HCs) are promising anodes of sodium‐ion batteries (SIBs) due to their high capacity, abundance, and low cost. However, the sodium storage mechanism HCs remains unclear with no consensus in literature. Here, based on correlation between microstructure Na behavior synthesized over a wide pyrolysis temperature range 600–2500 °C, an extended “adsorption–insertion” is proposed.
