Researchers at Tohoku University’s Advanced Institute for Materials Research (WPI-AIMR) and Institute for Materials Research in Japan have developed a framework to predict how the structure of solid-state Electrolytes can affect the performance of a battery. This framework can help in designing advanced batteries with improved energy storage capacity and safety.

Solid-state batteries are considered a safer alternative to traditional lithium-ion batteries. They eliminate the need for liquid electrolytes, which can be volatile, and are capable of holding more energy. However, effectively harnessing the structure-performance relationship of solid-state electrolytes has been a complex challenge.

The researchers focused on divalent closo-type complex hydride (CTCH) electrolytes as potential alternatives to lithium-ion technology. CTCH electrolytes can accelerate the rate at which positive ions diffuse during the battery operation, leading to improved conductivity. To understand the structure-performance relationship of CTCH electrolytes, the researchers combined a genetic algorithm with computational modeling. They successfully predicted the structural information and diffusion activation energies of the electrolytes, validating their framework.

This study opens up new avenues for designing high-performance and cost-effective electrolytes and provides a better understanding of other classes of solid-state electrolytes. The development of advanced batteries is crucial for achieving a sustainable future.
