Special Issue Information

Dear Colleagues,

This Special Issue on research progress in power-oriented solid-state lithium-ion batteries (SSLBs) delves into the cutting-edge advances and challenges in the field, highlighting the shift toward safer, more efficient battery technologies. Central to this issue is the development of innovative solid electrolytes that promise higher ionic conductivities and improved mechanical properties. These advancements aim to leverage the benefits of solid electrolytes for enhanced safety and higher energy densities, particularly through the potential integration of lithium metal anodes.

Addressing the critical issue of interfacial impedance, this Special Issue explores various strategies for stabilizing and optimizing the electrode–electrolyte interface, a key aspect in achieving high-power output and longevity in SSLBs. Innovative cell architectures and manufacturing techniques are also discussed, focusing on scalability and the adaptation of SSLBs to diverse applications, from electric vehicles to wearable electronics.

Moreover, this Special Issue underscores the ongoing efforts made to overcome the challenges of scaling up production, ensuring consistent performance, and reducing costs. By providing a comprehensive overview of the current research, material innovations, and future directions, this Special Issue aims to chart the path for SSLBs in powering the next generation of electronic devices and electric vehicles, marking a pivotal step toward a more sustainable and efficient energy future.

The failure mechanism of square lithium iron phosphate battery cells under vibration conditions was investigated in this study, elucidating the impact of vibration on their internal structure and safety performance using high-resolution industrial CT scanning technology. Various vibration states, including sinusoidal, random, and classical impact modes, were tested to simulate real-world usage scenarios. The findings demonstrate that different vibration conditions exert varying degrees of influence on the battery cells. Despite experiencing slight deformation and displacement after exposure to vibrations, their overall performance remains stable, with no significant safety hazards detected. Moreover, it was observed that while the side gap increases due to the partial absorption of impact load by both the battery cells and connection components, the bottom gap remains unchanged. This study holds immense significance in enhancing electric vehicle safety and reliability, while providing a scientific foundation for future optimization designs of lithium iron phosphate batteries.

Lithium-ion battery systems are a core component for electric mobility, which has become increasingly important in the last decade. The rising number of new manufacturers and model variants also increases competitive pressure. Competition is shortening development times. At the same time, the range of technology options for batteries is growing steadily. Fast and well-founded concept development is becoming even more essential in this increasingly complex environment. For this purpose, various model-based systems engineering (MBSE) methods are analyzed and evaluated. Based on this, the battery modeling framework is derived and described, tailored to the needs of battery development. The validation of the methodological approach is demonstrated by the simulation workflow from an electrical cell characterization to the thermal evaluation of different cooling methods. Full article
