Solid-state electrolytes (SSEs) have been the subject of research for about 200 years. To address the safety risk raised by the flammable liquid organic electrolytes and the penetration of lithium filaments (also known as lithium dendrites), SSEs with high mechanical strength were expected to provide a workable solution for rechargeable lithium metal batteries. Previous efforts have led to the considerable development of SSEs with varied chemistries, achieving comparable ionic conductivities (around 1 mS cm−1) with traditional liquid electrolytes at ambient temperature. The resurgence of energy-dense lithium metal batteries has propelled solid-state electrolytes (SSEs) into the spotlight, although they still struggle with dendritic penetration-related failure.
Compared to their electrochemical qualities, SSEs’ mechanical properties have received less attention in study. However, for the application scenario of batteries, measuring the mechanical properties of SSEs and examining the accompanying consequences are crucial.
Generally speaking, different mechanical conditions have an impact on the kinetics and electrochemical reactions in SSEs. Mechanical failure is intimately related to SSE degradation and dendritic penetration. As a result, mechanical engineering is emerging as a rising star in the quest to create SSEs that are better. Both internal structural flaws and external forces acting on the materials could cause stress. An “unstressed” reference with predetermined lattice characteristics should be found initially to categorize the various types of stress in SSEs.
Research has shown that now we can create solid-state lithium-ion batteries that are more durable, which could offer a potential strategy for high-energy and secure future models that will be employed in practical instances like electric automobiles.
“The harm that humans do to the environment is now widely recognized in our day and age. To finally lead us towards a more sustainable future, we expect that the scientific development of high-energy batteries will be accelerated by our battery and methodology.” To address the many difficulties posed by climate change, the University of Surrey is a preeminent research organization that emphasizes sustainability for the good of society.
Additionally, it is dedicated to leading the industry and enhancing its resource efficiency on its estate. It has promised to achieve carbon neutrality by 2030. It was placed 55th worldwide in April by the Times Higher Education (THE) University Impact Rankings, which evaluates the performance of more than 1,400 universities about the Sustainable Development Goals of the United Nations (SDGs).
