Solid Electrolyte: Strategies to Address the Safety of All Solid-State Batteries

Publication Name

Advanced Energy and Sustainability Research


Lithium metal batteries (LMBs) are in the spotlight as a next-generation battery due to their high theoretical capacity. However, LMBs still suffer from inferior cycle stability owing to dendritic lithium (Li) growth during Li plating and stripping, leading to battery explosion. To solve this problem, solid electrolytes have emerged as a promising candidate by suppressing the dendritic Li growth. Despite numerous efforts, however, many challenges, such as low ionic conductivity, air stability, space charge layer, and contact loss issues, have been encountered. This review aims to provide the current challenges and new insights of solid electrolytes and then explore optimal solutions for next-generation solid electrolytes.
