Electrospun Cobalt Based Composites as Anodes for Lithium-Ion Batteries

  • Author(s) / Creator(s)
  • Owing to its high energy density, simple device design, and flexibility; Lithium-ion batteries (LIBs) have attracted much consideration as the most promising energy storage devices for their wide application in mobile phones, laptops, and also in electric vehicles. One of the critical parts of commercial LIBs which significantly affects its performance is the anode materials. The archetypal anode material applied for LIB is carbon-based nanostructures due to its stable solid electrolyte interface and remarkable conductivity. However, the low specific conductivity of these carbonaceous materials paves researchers to develop new potential alternatives. In this regard, different transition metal-based anode materials and their composites with carbon have demonstrated much high theoretical capacitance. Among these, CoO and Co3O4 with porous carbon nanofiber composites showed an incredible capacity of 952 mAh g−1 after 100 cycles and equally exceptional rate performance at high current densities. Such free-standing nanofibers (NFs) of cobalt-based composites can be prepared via the electrospinning technique by applying the electric field between the nozzle and collector while introducing the polymeric solution. This low-cost, one-step fabrication process devoid of using any hazardous chemical is found to be sustainable and successfully scaled up for massive production of ready to use binder-free anodes for industrial applications. Additionally, the facile tuning of the surface area, porosity, and composition added the broad applicability of electrospun NFs as battery electrodes. Therefore, this chapter summarizes the current achievements, the challenges, and opportunities for future research on electrospun cobalt-based nanocomposites as anodes for LIBs.
