Abstract

Abstract : The figure of schematic illustration for the formation process of VN@C hollow structures. Abstract : A rationally designed strategy was employed for the preparation of VN@C hollow structures using ZIF-8 polyhedra as sacrificial templates. Meanwhile, ZIF-8 also plays the role of both nitrogen and carbon sources during the synthetic process. Benefiting from the unique loose hollow structure with high surface area of VN@C, as well as the support of carbon, the product displays an outstanding lithium storage performance. The discharge capacity can reach 495.3 mA h g −1 at 1 A g −1 after 500 cycles.
