“…The conventional speed of the coating and drying process in battery manufacturing ranges from 25 to 100 m/min. − The production of an electrode begins with the preparation of battery slurries by mixing active materials, conductive agents, polymeric binders, and solvents. The rheological properties, adhesive strength, and microstructure of the slurry play a crucial role in the subsequent coating and drying process. − The slurry is then coated onto a substrate, such as Cu or Al foil, and the solvent is evaporated, resulting in the formation of a dried electrode.…”

Lithium-ion battery manufacturing is time-and energy-intensive because of the drying process. While current approaches aim to accelerate drying by reducing the amount of solvent, they compromise uniformity and pose challenges in mass production. This study introduces the dewatering concept, which is widely used in paper manufacturing, to the electrode manufacturing process and proposes a high-speed electrode manufacturing process applying dewatering (HEMPAD). It encompasses four sequential stages: casting battery slurries onto porous media, forming a filter cake through solvent dewatering, transferring the filter cake to a substrate, and subsequent drying of the filter cake. HEMPAD achieves a substantial reduction in processing time and energy consumption, effectively filtering out over 40% of the solvent during dewatering. The investigation encompasses an analysis of the microstructure and electrochemical properties under different negative pressures. The results reveal that HEMPAD, in the absence of negative pressure, displays a similar adhesion force and superior electrochemical performance compared to the conventional process. The introduction of HEMPAD in the electrode manufacturing process is promising for next-generation battery production as it enables faster drying speed, less energy consumption, and relatively stable electrochemical performance.

“…Nowadays, although lithium battery vehicles are developing rapidly owing to the environmental pollution and energy shortage, the number of internal combustion engine (IC) vehicles still accounts for the largest part of the automobile market. Currently, three main divisions of power system of vehicles are gasoline engine, diesel engine, and lithium battery [9]. As for the former two, although the internal combustion engine technology is comparatively mature, there is still large space for its further development.…”

This paper presents a case study of a lithium battery and fuel cell integrated powertrain system for a renewable energy vehicle. The performance analysis includes evaluating the energy consumption of the vehicle and the efficiency of the power generation components. When driven solely by the lithium battery at average speeds of 15 km/h and 20 km/h, it was observed that speed significantly influences the travel distance of the vehicle, with higher speeds resulting in lower mileage. The energy efficiency rates were found to be 89.3% and 85.7% at speeds of 15 km/h and 20 km/h, respectively, indicating an 18.1% decrease in efficiency from low to higher speeds. When the lithium battery is solely charged by the hydrogen fuel cell, the efficiency under test conditions reaches approximately 32.5%. In the “FC + B + SC” driving mode, which combines the use of the lithium battery, fuel cell, and solar panel to power the vehicle, the travel range can be extended to 50.62 km and 42.05 km, respectively, representing an increase of over 50%, with overall efficiencies of 63.8% and 60.7%, respectively. This hybrid powertrain system exhibits rapid dynamic response, high energy and power density, and enables longer travel distances for the renewable energy vehicle.

“…NDT refers to a range of methods for evaluating and localizing anomalies such as imperfections, corrosion, deformation, discontinuities, external and internal cracks, etc., during the production and life cycles of LIBs, without compromising the original part, in accordance with the applicable standards [17][18][19]. In recent years, significant steps have been made in the development of accurate, non-invasive, and reliable methods for the estimation of battery performance.…”

Lithium-ion batteries are considered the most suitable option for powering electric vehicles in modern transportation systems due to their high energy density, high energy efficiency, long cycle life, and low weight. Nonetheless, several safety concerns and their tendency to lose charge over time demand methods capable of determining their state of health accurately, as well as estimating a range of relevant parameters in order to ensure their safe and efficient use. In this framework, non-destructive inspection methods play a fundamental role in assessing the condition of lithium-ion batteries, allowing for their thorough examination without causing any damage. This aspect is particularly crucial when batteries are exploited in critical applications and when evaluating the potential second life usage of the cells. This review explores various non-destructive methods for evaluating lithium batteries, i.e., electrochemical impedance spectroscopy, infrared thermography, X-ray computed tomography and ultrasonic testing, considers and compares several aspects such as sensitivity, flexibility, accuracy, complexity, industrial applicability, and cost. Hence, this work aims at providing academic and industrial professionals with a tool for choosing the most appropriate methodology for a given application.
