On this research, a SiOx embedded inside a pressed Cu mesh (SPCM) anode was developed to mitigate structural degradation and interfacial instability throughout biking. The four-sided confinement of the pressed Cu mesh mechanically supported the energetic materials, suppressing quantity growth and enabling multidirectional electron pathways for uniform cost distribution. SPCM which is incorporating 0.40 wt% single-walled carbon nanotubes (SWCNTs) (denoted as SPCM-40) additional enhanced interparticle conductivity and mechanical integrity. Consequently, the SPCM-40 electrode exhibited superior biking stability and price functionality in contrast with a standard Cu-foil-based SiOx electrode (SF), delivering an preliminary capability of ~1800 mAh g⁻¹ and an areal capability of three.2 mAh cm⁻². Structural and electrochemical analyses comparable to SEM, EDS, GITT, EIS, and XPS confirmed suppressed pulverization, improved Li-ion transport, and formation of a LiF-rich SEI. Delamination and cracking led the SF electrode to increase by 267% within the vertical route, whereas the SPCM-40 electrode exhibited solely 117% growth. In a pouch-cell configuration with an NCM811 cathode, the SPCM-40 maintained secure biking over 100 cycles and achieved a theoretical power density 1.4 occasions greater than that of the Cu-foil SiOx electrode. This work highlights a easy but efficient current-collector engineering technique for attaining graphite-free, high-stability SiOx anodes for next-generation lithium-ion batteries.
