Composed of environmentally friendly, abundant elements, this material possesses exceptional Li ion conductivity, enabling it to outperform other solid materials in this regard. What sets it apart is its unique structure, propelling it ahead of conventional solid-state electrolytes. In the past, the scientific community believed that only solid materials with a limited range of ionic environments could achieve high-performance Li ion conductivity. However, this breakthrough study challenges that notion, showcasing the remarkable performance of materials with multiple coordination environments for mobile ions. This revelation expands the chemical space available for further exploration and opens up new possibilities for material discovery and design.

While recent reports highlight the use of artificial intelligence (AI) tools in material discovery, this study demonstrates the power of combining AI with the expertise of researchers. Rather than allowing AI tools to work independently and potentially recreate known materials, the University of Liverpool’s research team skillfully harnessed the computational power of AI and physics-based calculations to inform the decision-making process of chemistry experts. This collaborative approach, leveraging the strengths of both humans and machines, enabled the successful discovery of this groundbreaking material. By focusing on meaningful differences in composition and structure and assessing their impact on material properties, this research introduces a disruptive design approach that can be applied to the development of future high-performance materials reliant on fast ion motion in solids.

The discovery of this highly conductive solid material not only offers immediate benefits in the field of Li ion battery technology but also serves as a platform for future advancements in the field of materials science. The novel understanding gained from this study paves the way for optimizing the properties of this material, further enhancing its capabilities. Moreover, this newfound knowledge can be extended to identify and design other materials based on similar principles. By expanding the chemical space for exploration, researchers can embark on a journey of unprecedented material discovery and design, leading to the development of more efficient and sustainable energy solutions.

The study conducted by the University of Liverpool involved a collaborative effort amongst various research centers and departments. Researchers from the Department of Chemistry, the Materials Innovation Factory, the Leverhulme Research Center for Functional Materials Design, the Stephenson Institute for Renewable Energy, the Albert Crewe Center, and the School of Engineering all contributed to this groundbreaking discovery. This interdisciplinary approach allowed for the utilization of different areas of expertise, ultimately leading to a successful outcome.

The discovery and design of new materials to address global priorities, such as Net Zero solutions, remains a grand challenge for materials science. The recent breakthrough achieved by the University of Liverpool in the realm of Li ion conductivity offers a promising solution to this challenge.
