Abstract –
Solid-state batteries (SSBs) represent a promising advancement in green energy storage, offering superior energy density, enhanced safety, and longer lifespans compared to conventional lithium-ion batteries. These features make SSBs highly attractive for applications in electric vehicles, renewable energy systems, and portable electronics, aligning with the global shift toward sustainability. The key to their performance lies in the use of solid electrolytes, which eliminate the flammability and leakage issues of liquid electrolytes, enabling the development of safer and more efficient energy storage solutions. Despite their potential, SSBs face several challenges, including high manufacturing costs, scalability issues, and material limitations, particularly with solid electrolytes and interfacial stability. The development of suitable solid electrolyte materials that offer both high ionic conductivity and mechanical strength remains a critical hurdle. Additionally, optimizing the battery’s architecture to minimize resistance and maximize energy output while maintaining stability over multiple charge-discharge cycles is essential. Ongoing research and innovation in materials science, manufacturing techniques, and system integration are crucial to overcoming these obstacles. As these advancements are realized, solid-state batteries have the potential to revolutionize energy storage, contributing significantly to the decarbonization of energy systems and the broader adoption of renewable energy technologies.
