Laser micro-welding of stainless steel foil: Welding mode, microstructure and corrosion properties SCIE
期刊论文 | 2023 , 161 | OPTICS AND LASER TECHNOLOGY
Abstract&Keyword Cite

Abstract :

Laser micro-welding differs from macro-welding in that at least one dimension of the weld is less than 100 mu m. Although process research on laser micro-welding has recently made some progress, the influence of welding mode on microstructure and corrosion resistance has remained unknown, which has been shown to have a significant influence on laser macro-welding. In this work, a single-mode fiber laser equipped with a scanning galvanometer is used to weld AISI304 stainless steel foils with a thickness of 100 mu m. Similar to laser macro -welding, keyhole formation is used to describe two welding modes, namely thermal conduction welding and penetration welding. The laser-material interaction experiences a transient phase in which the welding mode alternates between conduction welding and penetration welding as reported by previous work. However, we show that gas protection eliminates the transient phase, proving that the transient phase develops as a result of the unsteadiness of the penetration welding caused by oxidation during the welding process. The crystallographic texture and phase constitution vary between conduction and penetration welds due to variations in heat transfer behavior during welding. The conduction weld has greater sigma 3 CSL boundaries and a more uniform micro-structure than the penetration weld, resulting in better corrosion resistance.

High-Efficiency and Low-Intensity Threshold Femtosecond Laser Direct Writing of Precise Metallic Micropatterns on Transparent Substrate SCIE
期刊论文 | 2023 , 8 (8) | ADVANCED MATERIALS TECHNOLOGIES
Abstract&Keyword Cite

Abstract :

Laser direct writing (LDW) is a promising approach for fabricating metallic micropatterns on transparent substrates for transparent electronic circuits that satisfy both electronic and optical criteria. However, high efficiency and precision patterning remain a challenge for both photochemical and photothermal LDW. Here, a novel method is proposed with a femtosecond laser to achieve a highly-efficient photothermal process via single-photon absorption by photosensitive particles (SPA-FsLDW). The dispersive photosensitive particles act as numerous heating sources, enabling simultaneous multiple-location photothermal reactions and highly-efficient metallization due to heat-induced metal ion reduction. The new approach effectively exploits the excellent heat-input regulation with the ultrashort pulse of the femtosecond laser to achieve great temperature controllability and precision. It is shown that, with a deposition rate of approximate to 10(7) mu m(3) s(-1) and electrical resistivity of approximate to 10(-7) omega m, SPA-FsLDW improves efficiency and electrical resistivity by at least one order of magnitude compared to previously reported FsLDW. A self-powered sensor is fabricated using SPA-FsLDW, demonstrating its practical applicability.

Alloy-Type Lithium Anode Prepared by Laser Microcladding and Dealloying for Improved Cycling/Rate Performance SCIE
期刊论文 | 2022 | ACS NANO
Abstract&Keyword Cite

Abstract :

Nanosized alloy-type materials (Si, Ge, Sn, etc.) present superior electrochemical performance in rechargeable batteries. However, they fail to guarantee cycling capacity and stability under high mass loading required by industrial applications due to low electric contact and adhesive strength, which has long been a challenge. This work proposes a rational design for an alloy-type anode via facile and versatile laser microcladding and dealloying. The proposed anode features a large area porous network composed of continuous nano-ligaments, which consist of evenly distributed nanosized alloy-type material metallurgically bonded with conductive material. The fabrication of the structure is validated using Ge-Cu and Sn-Cu anodes, both exhibiting enhanced cycling stability at high areal capacity and rate performance in lithium-ion batteries. The enhancement is attributed to the structural features, which contribute to lithiation-delithiation stability and intact electron/Li ion transference path, as verified by in situ and ex situ transmission electron microscopy observations. More importantly, the critical solidification conditions of laser microcladding are provided by a multiphysics simulation, allowing for a thorough understanding of the structural formation mechanism. The study provides a possible approach to improve mass loading and performance of an alloy-type anode for practical application.

Femtosecond Laser Direct Writing of Copper Microstructures with High Efficiency via Thermal Effect of Nanoparticles
期刊论文 | 2022 , 49 (8) | CHINESE JOURNAL OF LASERS-ZHONGGUO JIGUANG
Abstract&Keyword Cite

Abstract :

Objective The precise conductive Cu micropatterns have been used in a variety of electronic devices. Compared to other traditional fabrication methods, laser direct writing is more efficient and reliable. The femtosecond laser direct writing technique, in particular, is used to construct highly conductive Cu microstructures. Femtosecond laser with ultrashort pulse duration can precisely control the heat input resulting in the reduction of Cu2+ in the laser irradiation zone without the damage of substrate. However, the intensity is as high as 10(11) W . cm(-2) and the scanning speed is generally lower than 10 mm . s(-1) to achieve the necessary reduction temperature. Si nanoparticles were added to Cu2+ solution in this study, acting as photon-absorbing nanoparticles due to their narrow band-gap. The photon-absorbing nanoparticles reduced the volume of the reduction zone by decreasing the penetration depth. The temperature of the reduction zone was rising, resulting in more efficient and less expensive direct writing. As a result, the conductive Cu microstructures were deposited on the substrate with the intensity from 5.32 x 10(9) to 8.51 x 10(9) W . cm(-2) and the scanning speed from 100 to 500 mm . s(-1). The intensity was two orders of magnitude lower, and the direct writing efficiency was three orders of magnitude higher, compared to previously reported work. The impacts of scanning speed and intensity on the morphology, chemical composition, and conductivity of Cu microstructures were investigated. The lowest sheet resistance was 0.28 Omega . sq(-1) and the lowest electrical resistivity was 4.67 x 10(-6) Omega.m at the intensity of 5.32 x 10(9) W . cm(-2) with a scanning speed of 100 mm . s(-1), respectively. Methods The solvent was prepared by mixing 6 mL of ethylene glycol and 3 mL of deionized water. 4 g of Cu( NO3)(2) . 3H(2)O was added to the solvent with ultrasonication for at least 30 min to thoroughly dissolve Cu( NO3)(2) . 3H(2)O. For 2 minutes, the liquid was heated to 170 degrees C . The solvent received 100 mg of Si nanoparticles. To obtain the suspension liquid, the mixed solution was ultrasonically homogenized for 1 h. Glass was used as a substrate that was adhered to the suspension liquid ' s surface. The laser beam scanning was controlled by a femtosecond laser equipped with a galvanometer system. After the femtosecond laser irradiation, the conductive Cu microstructure was formed on the backside of the substrate. Then, the morphologies of the Cu microstructures were characterized by optical microscopy and field emission scanning electron microscopy. The composition of the Cu microstructures was verified using X-ray diffraction. The thickness of the microstructures was measured and the three-dimensional topography of the microstructures was depicted using a surface profiler. Cu microstructures' electrical properties were measured using a source meter based on the four-point probe method. Results and Discussions The continuity of laser-fabricated microstructures and the proportion of Cu increased with the increasing intensity ( Fig. 2 and Fig. 3) . The intensity was two orders of magnitude lower than that in previous experiments. The addition of photon-absorbing Si nanoparticles to the suspension liquid resulted in a decrease in laser penetration depth in solution, raising the temperature of the laser-induced reduction zone (Fig. 4) . The more metallic Cu was obtained. The continuity of microstructures and the proportion of Cu also increased with the decreasing scanning speed ( Fig. 5 and Fig. 6 ) . The direct writing efficiency was one to three orders of magnitude higher than that in previous work ( Table 1 ) . The sheet resistance and electrical resistivity of asfabricated Cu microstructures tended to decrease with increasing intensity or decreasing scanning speed ( Fig. 7) . The Cu microstructure obtained at 5.32 x 10(9) W . cm(-2) intensity and 100 mm . s(-1) scanning speed exhibited the lowest sheet resistance of 0.28 Omega . sq(-1). Moreover, as a result of the reduction reaction threshold, the microstructure' s line width was narrower than the laser spot' s diameter. As a result, the heat input to the irradiation zone was precisely controlled, limiting the reduction zone area and resulting in finer line width formation (Fig. 9) . Conclusions In this study, highly conductive Cu microstructures were formed on a glass substrate using femtosecond laser direct writing. As photon-absorbing nanoparticles, Si nanoparticles were added to the precursor solution. With the intensity ranging from 5.32 x 10(9) W . cm(-2) to 8.51 x 10(9) W . cm(-2) and the scanning speed ranging from 100 mm.s(-1) to 500 mm . s(-1), the Cu microstructures were formed on substrates. Metallic copper, Cu2O, and minor Si were found in the copper microstructures. The results show that the continuity of the microstructure, the proportion of Cu, and the conductivity of the microstructures all increased with increasing intensity or decreasing scanning speed. At the scanning speed of 100 mm.s(-1) , the lowest sheet resistance of 0.28 Omega. sq(-1) and the lowest electrical resistivity of 4.67 x 10(-6) Omega . m were obtained. The intensity was two orders of magnitude lower than that in previous work, and the direct writing efficiency was one to three orders of magnitude higher than that in previous work. Moreover, the line width of the microstructure was significantly smaller than the diameter of the laser spot.

Abstract :

People are becoming more conscious of the necessity of sustainable development, and waste recycling is getting increased attention. As for the highly concerned Si in lithium-ion batteries (LIBs), the recycled nanoscale Si displays a small packing density that would impede its industrialization. Moreover, Si recycling commonly shows a lengthy process and specialized device usage, resulting in high energy/cost consumption and pollution. This study employs waste Al-Si alloy as raw materials and proposes a hypothermal chemical corrosion method to recycle and construct micrometer-sized spongy Si. The nanopores/nanoskeletons in the spongy Si and the amorphous carbon coating (Si@C) regulate electron/lithium ion transference, capacitance behavior, and structural stability to achieve high areal/volumetric capacity and cycling performance. The spongy Si@C anode delivers an areal and volumetric capacity of 1.13 mAh cm(-2) and 1909 mAh cm(-3) (0.05 C), respectively. Increasing mass loading further improves areal capacity to 2.52 mAh cm(-2) (0.1 mA cm(-2)) which retains 0.89 mAh cm(-2) after 100 cycles at 1.2 mA cm(-2). Furthermore, in the full-cell configuration, the initial energy density is 483 Wh kg(-1) at 0.5 C, and the capacity retention is 84% after 150 cycles at 2 C. This study provides novel insights into the efficient and economical fabrication of high-performance LIBs.

Abstract&Keyword Cite

Abstract :

In a wide range of applications, rapid fabrication of metallic patterns on a transparent substrate is highly desired. In this work, a highly conductive Cu wire with a sheet resistance of 0.27 omega/sq is deposited on glass through femtosecond laser-induced reduction of Cu ions. The present work improves the deposition efficiency by at least one order of magnitude compared to previous works. The effects of scanning speed, laser intensity, and effective pulse number on composition, morphology, dimensions, and conductivity of the deposited Cu are investigated. The process window is established with the goal of achieving optimal laser parameters for creating highly conductive Cu. With a scanning speed of 600 mm/s, an intensity of 1.21 x 10(10) W/cm(2), and an effective pulse number of 38500, the well-formed Cu in the process window has a sheet resistance of less than 1 omega/sq and the highest deposited efficiency of 4.60 x 10(7) mu m(3)/s. The current-carrying performance of the deposited Cu is also investigated for prospective use as a circuit material, demonstrating the Cu wire's electrical and thermal durability. In addition, temperature rise could be estimated from Cu wire width and sheet resistance with given Cu wire length and applied current, which could aid in laser parameter selection.
