The growing demand for portable devices and electric vehicles has significantly accelerated the development of lithium-ion batteries, driving innovation towards achieving higher energy density, greater power output, and enhanced safety.[1] Currently, graphite anodes, with a theoretical capacity of 372 mAh g⁻¹, are widely used but remain a limiting factor. In contrast, lithium metal anodes offer a much higher theoretical capacity of 3860 mAh g⁻¹, making them promising candidates for next-generation lithium batteries that prioritize high energy density and extended cycle life.[2] However, challenges such as the irreversible loss of lithium due to dendrite formation, whisker growth, and the generation of "dead lithium" pose significant safety risks.

To address these issues, anode-less lithium battery design has emerged as a promising alternative, offered the highest achievable energy density while mitigating safety concerns.

In this study, an ultrathin layer was deposited onto a copper foil using physic-chemical methods, enabling its use as negative electrode in a quasi-anode-less lithium metal battery configuration. Electrochemical testing in a coin cell setup demonstrated notable performance improvements compared to traditional anode-less systems. Detailed morphological and compositional analyses of the thin layer, functioning as a solid electrolyte interphase, were conducted using SEM and XPS techniques. These findings lay a robust foundation for further research, aiming to enhance stability and extend the lifespan of lithium metal batteries through practical design optimizations.[3]
