“…In addition to being an additive to silicon anodes, carbon nanotubes can also be used to modify other anode types due to their flexibility and electron conductivity. Among the candidate materials for the fabrication of lithium-ion batteries with long life and reasonable stability is lithium titanate [11]. It is possible to support the microstructure of this type of anode using carbon nanotubes of relatively high strength, which are able to overcome the issue of low conductivity and lithium-ion storage inherent to this type of anode.…”

Commercially, lithium-ion batteries are the most popular batteries for electric devices, while energy density and stability have become more important for electric vehicles. Therefore, there is an increased interest in producing advanced lithium-ion batteries with a greater range of electric storage capability and improved electron transfer efficiency. Over the past few years, nanotechnology has been widely applied to enhance the physical properties of materials through the application of surface treatments or the modification of nanostructures. The significant development potential of nanotechnic applications for lithium-ion batteries is the reason for this discussion. There have been several advancements in graphene, carbon nanotubes, silicon-based and other metal-based anodes, lithium cobalt oxide, lithium iron phosphate, and nickel-based cathodes, their fabrication processes and understanding of mechanisms, as well as trends for further improvement of those previously discovered. These advancements have led to the development of batteries with greater capacity and greater performance, better stability, quicker charging times, and a longer cycle life.

Flexible and high‐performance lithium‐ion batteries (LIBs) encounter challenges due to the inherent trade‐offs in conventional electrode designs, particularly concerning mechanical flexibility and high energy density. Here, a novel percolative metal microweb‐based electrode, fabricated via electrohydrodynamic processes, yielding a three‐dimensional (3D) network structure with exceptional electrical properties and mechanical durability is introduced. This lightweight electrode design addresses the need for improved energy density by reducing the weight of the current collector, which typically accounts for more than 10% of the battery's weight. The 3D architecture of the electrode enhances the contact area with the electrolyte, thereby minimizing polarization voltage and improving lithium‐ion diffusion. Furthermore, the low coating thickness‐to‐weight ratio promotes electron transfer and mitigates capacity fade at high current densities. The microweb‐based full cell exhibits energy and power densities of 110 and 1,048 W kg⁻¹ at 10 C, respectively, which are the highest reported values among LIBs utilizing similar materials. The design of the electrode proposed in this study is expected to significantly contribute to the development of wearable and flexible electronics.
