High electrode performance of hydrothermally developed activated C coated O3–NaFeO2 electrode for Na-ion batteries applications

Owing to increase in cost and low availability of Li source causes the high rate of the energy storage devices. By focusing on these issues, the cost effective and high performed electrode is needed for energy storage application. Na based electrodes can replace the Li ion batteries because of the availability of Na is higher than the Li. The cost of the energy storage devices can be reduced by using Na instead of Li. Many other electrodes are reported based on Na ion batteries. Since in this present work we prepared O3–NaFeO2 (NIO) high performance electrode prepared by two step hydrothermal assisted solid-state method. But the battery performance of NaFeO2 is suffers from capacity decay during long term cycling. For these issues naturally derived sucrose from the sugarcane is prepared which increase the electrochemical performance of Ac carbon coated NaFeO2 (AC Coated NIO). The AC Coated NIO electrode delivers the capacity of about 131 mAh g−1 at 80 mA g−1. The retention capacity of material is about 92% after 100 cycles. Such electrochemical action of the current electrode can show the way to cost effective and highly performed Na ion electrode development for Energy storage devices.
