報告摘要:

The manifold consumption of lithium has resulted in an exponential price rise in the past decade, and it also brings fears of a potential lithium shortage in the future. Hence, sodium-ion batteries (SIBs), as a promising alternative to Li-ion batteries, would become more competitive in the coming half century because of the low cost and abundance of sodium sources.[1] Sodium-ion batteries with high power density present tremendous potential for large-scale energy storage applications. However, it remains a big challenge to develop suitable anode materials for ultrafast and highly reversible sodium ion storage. MXenes, a new family of 2D materials, are considered a rising star for energy storage due to their unprecedented combinations of properties: excellent electronic conductivity, hydrophilicity, mechanical flexibility and compositional adaptability.[2] The major drawback of MXene materials for battery applications is their low specific capacities, despite substantial improvements achieved. Many works has verified that MXenes could play an extraordinary synegistic role when combining with metal oxide materials.
