About the project
This research investigates the rapidly evolving field of solid-state lithium metal anode batteries (SSBs) and their potential to transform electric vehicle (EV) technology. It compares these emerging systems with current lithium-ion chemistries such as LFP, NMC, and NCA, highlighting how the replacement of liquid electrolytes with solid ones could significantly enhance safety and energy density. The study emphasizes the technical mechanisms behind SSBs—explaining how lithium migration and solid separators contribute to better thermal resistance and reduced risks of short circuits caused by dendrite formation.
However, the paper also offers a critical perspective on the major stability and performance challenges that currently prevent SSBs from large-scale commercial adoption. It categorizes these into chemical, electrochemical, mechanical, and thermal instabilities, showing how each affects longevity, efficiency, and manufacturability. Drawing on experimental findings and design proposals, the author reviews advanced mitigation techniques—such as interfacial coatings, gradient doping, multi-layer electrolytes, and improved cell and thermal management systems—that aim to overcome these obstacles.
Overall, the research situates solid-state batteries as a promising but technically demanding innovation. It underscores that while their advantages in safety, charge speed, and energy density could revolutionize electric mobility, achieving stability, low-cost production, and reliable performance across temperatures remains the key challenge before these batteries can replace today’s lithium-ion technology.
