Batteries 2022, 8, 181 10 of 12 References realizes higher specific capacity, rate capability, and capacity retention compared to the dense electrode (0.5 g/L), which can be induced by the improved diffusion coefficient and enriched electroactive sites in the electrochemical reactions of the Na ions with the electrode interfaces. In addition, the high-rate cycling capability of the open sponge-like electrode is noted in both the specific (100.1 mAh/g and 90.2% cycling retention after 100 cycles at 5 C). The superior electrochemical performance is attributed to the efficient and stable charge transportation via the open-pores networking electrode structure for providing the shortened diffusion pathway and improved specific surface area to the composite Na0.44MnO2 electrode. The Na0.44MnO2 active material exhibits reversible phase transition during the high-rate electrochemical reaction with Na ions as shown in the ex situ XRD. Additionally, the electrode structure is maintained over cycling as a result of maintaining the low internal resistance of the electrodes in the condition of increasing C-rate. To the best of the present authors’ knowledge, this is the first report on the unique design of the cathode electrodes with superior high-rate capabilities of the SIBs through the one-pot spraying process, and we believe that one-pot spray engineering can be utilized as a potential milestone to boost the development of advanced structures for high-rate and cycle-stable SIBs.
