| 5 | Recent progress in laser texturing of battery materials: a review of tuning electrochemical performances, related material development, and prospects for large-scale manufacturing显示文摘Traditional electrode manufacturing for lithium-ion batteries is well established,reliable,and has already reached high processing speeds and improvements in production costs.For modern electric vehicles,however,the need for batteries with high gravimetric and volumetric energy densities at cell level is increasing;and new production concepts are required for this purpose.During the last decade,laser processing of battery materials emerged as a promising processing tool for either improving manufacturing flexibility and product reliability or enhancing battery performances.Laser cutting and welding already reached a high level of maturity and it is obvious that in the near future they will become frequently implemented in battery production lines.This review focuses on laser texturing of electrode materials due to its high potential for significantly enhancing battery performances beyond state-of-the-art.Technical approaches and processing strategies for new electrode architectures and concepts will be presented and discussed with regard to energy and power density requirements.The boost of electrochemical performances due to laser texturing of energy storage materials is currently proven at the laboratory scale.However,promising developments in high-power,ultrafast laser technology may push laser structuring of batteries to the next technical readiness level soon.For demonstration in pilot lines adapted to future cell production,process upscaling regarding footprint area and processing speed are the main issues as well as the economic aspects with regards to CapEx amortization and the benefits resulting from the next generation battery.This review begins with an introduction of the three-dimensional battery and thick film concept,made possible by laser texturing.Laser processing of electrode components,namely current collectors,anodes,and cathodes will be presented.Different types of electrode architectures,such as holes,grids,and lines,were generated;their impact on battery performances are illustrated.The usage of high-energy materials,which are on the threshold of commercialization,is highlighted.Battery performance increase is triggered by controlling lithium-ion diffusion kinetics in liquid electrolyte filled porous electrodes.This review concludes with a discussion of various laser parameter tasks for process upscaling in a new type of extreme manufacturing. | Wilhelm Pfleging | 2021 | International Journal of Extreme Manufacturing2021,3,1: | 1 |

| 8 | Toward Shared Control Between Automated Vehicles and Users显示文摘Technological developments in the domain of vehicle automation are targeted toward driver-less,or driver-out-of-the-loop driving.The main societal motivation for this ambition is that the majority of(fatal)accidents with manually driven vehicles are due to human error.However,when interacting with technology,users often experience the need to customize the technology to their personal preferences.This paper considers how this might apply to vehicle automation,by a conceptual analysis of relevant use cases.The analysis proceeds by comparing how handling of relevant situations is likely to differ between manual driving and automated driving.The results of the analysis indicate that full out-of-the-loop automated driving may not be acceptable to users of the technology.It is concluded that a technology that allows shared control between the vehicle and the user should be pursued.Furthermore,implications of this view are explored for the concrete temporal dynamics of shared control,and general characteristics of human machine interface that support shared control are proposed.Finally,implications of the proposed view and directions for further research are discussed. | Jacques Terken Bastian Pfleging | 2020 | Automotive Innovation2020,3,1: | 1 |

| 12 | Laser-Treated Surfaces for VADs:From Inert Titanium to Potential Biofunctional Materials显示文摘Objective.Laser-treated surfaces for ventricular assist devices.Impact Statement.This work has scientific impact since it proposes a biofunctional surface created with laser processing in bioinert titanium.Introduction.Cardiovascular diseases are the world’s leading cause of death.An especially debilitating heart disease is congestive heart failure.Among the possible therapies,heart transplantation and mechanical circulatory assistance are the main treatments for its severe form at a more advanced stage.The development of biomaterials for ventricular assist devices is still being carried out.Although polished titanium is currently employed in several devices,its performance could be improved by enhancing the bioactivity of its surface.Methods.Aiming to improve the titanium without using coatings that can be detached,this work presents the formation of laser-induced periodic surface structures with a topology suitable for cell adhesion and neointimal tissue formation.The surface was modified by femtosecond laser ablation and cell adhesion was evaluated in vitro by using fibroblast cells.Results.The results indicate the formation of the desired topology,since the cells showed the appropriate adhesion compared to the control group.Scanning electron microscopy showed several positive characteristics in the cells shape and their surface distribution.The in vitro results obtained with different topologies point that the proposed LIPSS would provide enhanced cell adhesion and proliferation.Conclusion.The laser processes studied can create new interactions in biomaterials already known and improve the performance of biomaterials for use in ventricular assist devices. | Eduardo Bock Wilhelm Pfleging Dayane Tada Erenilda Macedo Nathalia Premazzi Rosa Sá Juliana Solheid Heino Besser Aron Andrade | 2022 | Biomedical Engineering Frontiers2022,3,1: | 0 |
| 13 | Targeting new ways for large-scale,high-speed surface functionalization using direct laser interference patterning in a roll-to-roll process显示文摘Direct Laser Interference Patterning(DLIP)is used to texture current collector foils in a roll-to-roll process using a high-power picosecond pulsed laser system operating at either fundamental wavelength of 1064 nm or 2nd harmonic of 532 nm.The raw beam having a diameter of 3 mm@1/e^(2) is shaped into an elongated top-hat intensity profile using a diffractive so-called FBS■-L element and cylindrical telescopes.The shaped beam is split into its diffraction orders,where the two first orders are parallelized and guided into a galvanometer scanner.The deflected beams inside the scan head are recombined with an F-theta objective on the working position generating the interference pattern.The DLIP spot has a line-like interference pattern with about 15μm spatial period.Laser fluences of up to 8 J cm^(-2) were achieved using a maximum pulse energy of 0.6 mJ.Furthermore,an in-house built roll-to-roll machine was developed.Using this setup,aluminum and copper foil of 20μm and 9μm thickness,respectively,could be processed.Subsequently to current collector structuring coating of composite electrode material took place.In case of lithium nickel manganese cobalt oxide(NMC 622)cathode deposited onto textured aluminum current collector,an increased specific discharge capacity could be achieved at a C-rate of 1℃.For the silicon/graphite anode material deposited onto textured copper current collector,an improved rate capability at all C-rates between C/10 and 5℃ was achieved.The rate capability was increased up to 100%compared to reference material.At C-rates between C/2 and 2℃,the specific discharge capacity was increased to 200 mAh g^(-1),while the reference electrodes with untextured current collector foils provided a specific discharge capacity of 100 m Ah g^(-1),showing the potential of the DLIP technology for cost-effective production of battery cells with increased cycle lifetime. | Christoph Zwahr Nicolas Serey Lukas Nitschke Christian Bischoff Ulrich Radel Alexandra Meyer Penghui Zhu Wilhelm Pfleging | 2023 | International Journal of Extreme Manufacturing2023,5,3: | 0 |
| 14 | Effects of self-healing biomimetic subsoiler on tillage resistance, wearcorrosion performance and soil disturbance morphology under different soil types显示文摘Subsoiling has been widely used all over the world as an important operation method of no-tillage farming.For energy-saving and life-extension,the tillage resistance and wear-corrosion of subsoilers have attracted wide attention.In this study,the tillage resistance,soil disturbance,wear and corrosion of subsoiler with S-T-SK-2#biomimetic structures(S means subsoiler;T means tine;SK means shank;2#,h/s=0.57,h=5 mm andα=45°.)and self-healing coating under two seasons,two locations with different soil properties(black loam and clay soil)and subsoiling speeds(2 km/h and 3.6 km/h)were investigated.The soil moisture content and compactness affected the tillage resistance and wear-corrosion.The tillage resistance and degree of corrosion on all subsoilers were much larger in clay soil than that in black loam soil.Compared with S-T-SK-2#,the tillage reduction rate of C-S-T-SK-2#(S-T-SK-2#with self-healing coating)was up to 14.32%in clay soil under the speed of 2 km/h.The significance tests of regression equation results showed that subsoiler type and soil properties had a significant impact on soil disturbance coefficient,swelling of total soil layer,bulkiness of the plough pan.It is of a guiding significance for the analysis of soil disturbance.Synergism mechanism of subsoiler coupling with biomimetic structures and self-healing coating was analyzed in following.It depicted the guiding effect of biomimetic structure and the shield function of self-healing coating,resulting in anticorrosion and wear resistance of subsoiler. | Yueming Wang Chenjie Lu Jing Chen Chenhuan Cui Yijie Pan Wilhelm Pfleging Jiyu Sun | 2023 | International Journal of Agricultural and Biological Engineering2023,16,3: | 0 |
