title: An investigation of a novel MnO₂ network-Ni/PVDF double shell/core membrane as an anode for lithium ion batteries.
abstract: A novel MnO2 network-Ni/PVDF double shell/core fiber membrane is synthesized for the first time as an anode material for lithium ion batteries. The freestanding MnO2 nanosheet network is grown directly onto a conductive network-Ni/PVDF shell/core fiber membrane 3D current collector, avoiding the application of binders and conductive additives and simplifying the fabrication processing. The MnO2 nanosheet network can be tightly anchored to the Ni/PVDF fiber 3D current collector, and some small pores between the fibers and between the MnO2 nanosheets lead to fast charge transfer and ion transport. The unique MnO2 network-Ni/PVDF double shell/core fiber membrane exhibits a high charge/discharge capacity, long-term cycling stability and good rate capability.
