“…Li ions stored near the surface of SSE and CAM particles may be vulnerable to the heat generated during the ablation process. As summarized in Table 1, the studies on laser ablation of SSE and CAM particles have been successfully achieved using ultrafast pulsed laser sources [36–39, 86–94] . Recent works have secured high laser scan rates (>0.1 m s −1 ) by introducing a galvo‐scanning mirror optic system with high pulse repetition rates (~100 kHz).…”

“…reported an interface control technology combining laser ablation and ionic liquid electrolytes. A Li 1.5 Al 0.5 Ge 1.5 (PO 4 ) 3 (LAGP) SSE films (thickness=200 μm) with numerous through‐holes (diameter=20 μm) filled with ionic liquids were successfully prepared through the ultrafast pulsed laser ablation (pulse duration=228 fs) [91] . An electrolyte with this structure could shorten the length of Li‐ion conduction and improve the wettability between the electrolyte and the electrode.…”

“…In contrast, the SSB with pristine LAGP films showed poor capacity retention after the 11 th cycle. The same research group has reported a study on the surface treatment of LAGP SSE with ionic liquid [92] . To reduce interfacial impedance, surface texturing on the LAGP was conducted using an ultrafast pulsed laser, followed by the surface wetting of ionic liquids.…”

“…To reduce interfacial impedance, surface texturing on the LAGP was conducted using an ultrafast pulsed laser, followed by the surface wetting of ionic liquids. Further, the researchers applied ultrafast pulsed laser ablation technology to sodium SSBs, and completed surface texturing through fs laser etching without contamination or crystalline change of Na 3 Zr 2 Si 2 PO 12 (NZSP) SSE pellets [93] . However, the performance of the assembled full cell was unsatisfactory because the sharp corner of the textured‐SSE layer may generate non‐uniform current distribution, and related follow‐up studies are required.…”

Safe and high‐energy‐density solid‐state batteries (SSBs) are promising candidates for use as the primary power source of next‐generation electric vehicles. However, their poor rate capabilities and long‐term cyclabilities because of material and interfacial instabilities have hindered their widespread commercialization. This study reviewed the recent progress of laser‐assisted interfacial engineering technologies to address the stability issues at the interfaces of SSBs. First, the overview of the interfacial issues of SSBs is briefly outlined. Subsequently, the recent achievements are summarized according to the photophysical mechanisms of laser processing and the type of interfaces to which they are applied. Consequently, the critical laser processing factors to improve the interfacial stabilities of SSBs are highlighted in detail. Finally, the future challenges and opportunities in laser‐assisted interfacial engineering for manufacturing high‐performance SSBs have been discussed to provide guidelines for developing reliable and scalable processes.

Incorporating lithium metal anodes in next‐generation batteries promises enhanced energy densities. However, lithium's reactivity results in the formation of a native surface film, affecting battery performance. Therefore, precisely controlling the chemical and morphological surface condition of lithium metal anodes is imperative for producing high‐performance lithium metal batteries. This study demonstrates the efficacy of laser treatment for removing superficial contaminants from lithium metal substrates. To this end, picosecond‐pulsed laser radiation is proposed for modifying the surface of lithium metal substrates. Scanning electron microscopy (SEM) revealed that different laser process regimes can be exploited to achieve a wide spectrum of surface morphologies. Energy‐dispersive X‐ray spectroscopy (EDX) confirmed substantial reductions of ≈80% in oxidic and carbonaceous surface species. The contamination layer removal translated into interfacial resistance reductions of 35% and 44% when testing laser‐cleaned lithium metal anodes in symmetric all‐solid‐state batteries (ASSBs) with lithium phosphorus sulfur chloride (LPSCl) and lithium lanthanum zirconium oxide (LLZO) solid electrolytes, respectively. Finally, a framework for integrating laser cleaning into industrial battery production is suggested, evidencing the industrial feasibility of the approach. In summary, this work advances the understanding of lithium metal surface treatments and serves as proof of principle for its industrial applicability.
