Abstract
Anode free alkali metal batteries, favored by the small volume and high energy density, are plagued by the poor interfacial stability of the deposited metals. The successful stabilization of sodium (Na) in the glyme-based electrolytes has made the anode free Na metal battery a promising candidate in place of the commercial lithium ion batteries. Na 3 V 2 (PO 4 3 (NVP), a cathode material with high stability, will be studied in this independent study to improve the performance of the anode free Na metal battery. High quality NVP will be synthesized through hydrothermal assisted sol gel method and applied in anode free SIBs. Control experiments will be performed to explore the best synthesis condition such as annealing temperature annealing time, and material adding order, which guarantees the performance and stable output. The amount of carbon coating which improves the active material conductivity but decreases the overall capacity is optimized.
