Amid the global shift toward a green and low-carbon energy landscape, the demand for high-energy-density lithium batteries has surged exponentially across sectors such as new energy vehicles, advanced energy storage systems, and consumer electronics. As conventional lithium-ion battery technologies approach their theoretical performance limits (graphite anodes have a theoretical specific capacity of only 372 mAh/g), the industry urgently requires breakthrough materials to overcome energy density constraints. Silicon-based anode materials, with their exceptional theoretical specific capacity (up to 4,200 mAh/g—approximately 11 times that of graphite anodes) and suitable lithium intercalation potential, have emerged as a pivotal material poised to drive the next generation of battery technology. It is widely anticipated that 2025 will mark the "first year of large-scale adoption" of silicon-based anodes, signifying a critical transition from fundamental material innovation to commercial implementation in the lithium battery industry.

Despite the remarkable performance advantages of silicon-based anodes, their industrialization process still faces multiple technical barriers, such as:

Volume Expansion Effect: Silicon materials undergo a volume expansion rate of up to 300% during charge-discharge cycles, leading to particle pulverization, detachment of active materials, and collapse of the electrode structure;

Interfacial Stability Challenges: Repeated volume changes cause continuous growth and thickening of the solid electrolyte interface (SEI) layer, resulting in irreversible lithium-ion loss and degradation of conductivity;

Conductivity Limitations: The intrinsically poor electrical conductivity of silicon restricts the achievement of high-rate performance.
