Synergistically advancing Li storage property of hydrothermally grown 1D pristine MnO2 over a mesh-like interconnected framework of 2D graphene oxide

Here, we present a unique morphology comprising a blend of ultrafine 1D MnO2 and graphene oxide as an efficient anode material to overcome the issue of continuous capacity fading upon prolong cycling as suffered by almost every electrode materials. The graphene oxide sheets and -MnO2 nanorods are likely to display Van der Walls interactions in the as-prepared nanocomposite, offering a synergistic effect with high electron conductivity and reduced Li-ion path diffusion to improve the lithiation and de-lithiation processes. Therefore, the hybrid nanocomposite exhibited higher capacity of 1160mAhg(-1) as against 938mAhg(-1) displayed by the pristine -MnO2 nanorods at 0.1 C-rate after 100cycles, with a coulombic efficiency of about 99%. A linear rise in capacity was observed predominantly after similar to 30cycles, which remained unchanged even after the introduction of graphene oxide. This promising behavior can be attributed to the unique morphologies of the samples synthesized with meticulous optimizations via a single-step hydrothermal route.
