Silicon can store far more energy than graphite—the material used in the anode, or negatively charged end, of nearly all lithium-ion batteries. Silicon-dominant anodes are used in niche
Besides, ultralong LiV 3 O 8 nanowires have been synthesized by topotactic lithiation of H 2 V 3 O 8 nanowires (Xu et al., 2012).The LiV 3 O 8 nanowire cathode showed excellent high-rate capability and cycling stability. The excellent performance can be attributed to the low-charge-transfer resistance, good structural stability, large surface area, and suitable

A nanowire battery uses nanowires to increase the surface area of one or both of its electrodes, which improves the capacity of the battery.Some designs (silicon, germanium and transition metal oxides), variations of the lithium-ion battery have been announced, although none are commercially available. All of the concepts replace the traditional graphite anode and could

Keywords: silicon nanowire, nanowire array, silicon anode, n-type silicon anode, Li-ion battery. 1. Introduction. Lithium-ion batteries (LIBs) are among the most robust energy storage devices due to their good cycle life, low self-discharge, and high energy density [1,2].
With new possibilities, silicon and silicene nanocomposites, especially with safe solid-state superionic conductors, would be important for many solid-state electronic and energy generating devices, e.g., all-solid-state lithium-ion, metal-air, or lithium-air batteries, and dye-sensitized solar cell-Li-ion battery hybrids.
