“…In another study by the same group, line‐structured LATP SSEs were prepared by ultrafast pulsed laser ablation (pulse duration=8 ps) (Figure 5). [90] The X‐ray diffraction (XRD) analysis confirmed that the phase composition and crystal structures of the LATP layers were negligibly changed during ps laser ablation. Further, the tight adhesion between line‐structured SSEs and composite cathode was successfully obtained by filling LATP/CAM/polymer solid electrolyte mixture into the line‐patterned SSE layers (Figures 5b).…”

“…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).…”

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.

“…Kriegler et al fabricated directed permeable Li 1.5 Al 0.5 Ti 1.5 (PO 4 ) 3 (LATP) through laser ablation, as shown in Figure 11b. [55] A flexible polymer electrolyte was used to prepare the hybrid cathode and anode interface layers, which improved the conductive contact between the CAMs and SSEs and prevented the decomposition of LATP. The results show that the NCM622/Li cell has a specific capacity of 120.1 mA h g −1 , which is better than that of the unstructured sample for every performance.…”

The manufacturing and assembly of components within cells have a direct impact on the sample performance. Conventional processes restrict the shapes, dimensions, and structures of the commercially available batteries. 3D printing, a novel manufacturing process for precision and practicality, is expected to revolutionize the lithium battery industry owing to its advantages of customization, mechanization, and intelligence. This technique can be used to effectively construct intricate 3D structures that enhance the designability, integrity, and electrochemical performance of both liquid‐ and solid‐state lithium batteries. In this study, an overview of the development of 3D printing technologies is provided and their suitability for comparison with conventional printing processes is assessed. Various 3D printing technologies applicable to lithium‐ion batteries have been systematically introduced, especially more practical composite printing technologies. The practicality, limitations, and optimization of 3D printing are discussed dialectically for various battery modules, including electrodes, electrolytes, and functional architectures. In addition, all‐printed batteries are emphatically introduced. Finally, the prospects and challenges of 3D printing in the battery industry are evaluated.

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.
