The development of #energy #storage #technologies has been crucial for advancing contemporary technological capabilities, significantly contributing to the evolution of #sustainable energy systems. Throughout history, energy storage has undergone different phases, each marked by innovations that progressively improved the efficiency, safety, and environmental impact of these systems. Currently, we are observing a notable transformation in this field — a shift towards solidstate energy storage. This transition, highlighted by the development and deployment of solid-state batteries (#SSBs), represents not only a technological advancement but also addresses the increasing #global demand for more efficient, safer, and environmentally friendly energy solutions. This shift is driven by two primary factors. First, there is a growing recognition of the limitations inherent to traditional energy storage systems, especially those using liquid electrolytes, such as the used in lithium-ion #batteries. These limitations encompass concerns about safety, energy density, and long-term stability. Second, there has been substantial progress in the field of #materials #science, offering new avenues to surmount these limitations. The emergence of novel materials and innovative fabrication techniques has been crucial in the exploration and development of solidstate energy storage systems.
