The fabrication of foldable lithium-ion batteries with enhanced electrochemical performance has gained increased interest in the wearable electronics industry. To achieve this, flexible carbon current collectors with high capacity retention are key elements of their design. Here, we propose a material consisting of silicon nanosheets (SiNS) on flexible carbon textile (CT) for foldable lithium-ion batteries, combining the advantages of SiNS (e.g., high capacity, large surface area, and stress relaxation) with the ones of CT (e.g., foldability). The SiNS-CT anode was fabricated using two different methods: chemical vapor deposition and electrospray deposition. Both processes were found suitable for manufacturing. Under optimum conditions, the SiNS-CT anode showed good foldability with continuous potential stability during 100 bending cycles. Furthermore, this flexible electrode exhibited a high specific capacity (about 2500 mAh g-1) and an excellent coulombic efficiency (∼100%) throughout 200 cycles, achieving improved results when compared to silicon nanoparticles-carbon textile electrodes.
