Abstract
Na-ion batteries have received considerable attention in recent years but still face performance challenges such as limited cycle lifetime and low capacities at high current rates. In this work, we propose novel combinations of pre- and post-synthesis treatments to modify known Na-ion battery electrode materials to achieve enhanced electrochemical performance. We work with two model metal oxide materials to demonstrate the effectiveness of the different treatments. First, wet chemical preintercalation is combined with post-synthesis aging, hydrothermal treatment, and annealing of alpha-V2O5, resulting in enhanced capacity retention in a Na-ion battery system. The hydrothermal treatment resulted in an increased specific capacity of nearly 300 mAh/g. Second, post-synthesis acid leaching is performed on alpha-MnO2, also resulting in improved electrochemical capacity. The chemical, structural, and morphological changes brought about by the modifications are fully characterized.
