High performance Co3O4/Li2TiO3 composite hollow nanofibers as anode material for Li-ion batteries

Recent advances in electrospun magnetic nanofibers and their applications

“…As a new type of highenergy battery, the operation of a lithium ion battery is mainly based on the shuttle movement of lithium ions between the two poles. 126,127 The prospect of the development of lithium-ion batteries lies in having a higher energy density and longer cycle life, which are also the basic requirements for future electric vehicles and renewable energy storage. Low-dimensional materials, due to their excellent physical properties, large surface area and high porosity, can not only provide a larger electrode/ electrolyte interface, and shorten the path for the rapid diffusion of Li + ions and electrons, but also reduce the structural strain caused by the repeated Li + insertion/extraction process, making them play an increasingly important role in electrochemistry and energy storage.…”

“…Magnetic nanofibers prepared by electrospinning can potentially be used as electrode materials for the next generation of lithium batteries. 126,127,130 Jung et al prepared bubble-nanorod-structured Fe 2 O 3 -carbon nanofibers by electrospinning technology as a negative electrode material for lithium-ion batteries. 131 They used the diffusion process of the Kirkendall effect to completely convert the as-spun composite fiber into a bubble-nanorod structure Fe 2 O 3 -C composite nanofiber.…”
