All-solid-state lithium batteries have great potential for higher energy density and safety, but the poor electrode compatibility of solid electrolytes may cause electrolyte/electrode interface degradation, leading to battery failure. Mechanistic analyses and strategies for enhancing electrolyte/electrode interfaces are crucial for the future development of these batteries.
All-solid-state lithium batteries are promising next-generation energy storage devices that have gained increasing attention in the past decades due to their huge potential towards higher energy density and safety. As a key component, solid electrolytes have also attracted significant attention and have experienced major breakthroughs, especially in terms of Li-ion conductivity. However, the poor electrode compatibility of solid electrolytes can lead to the degradation of electrolyte/electrode interfaces, which is the major cause for failure in all-solid-state lithium batteries. To address this, this review will summarize the in-depth understanding of physical and chemical interactions between electrolytes and electrodes with a focus on the contact, charge transfer and Li dendrite formation occurring at electrolyte/electrode interfaces. Based on mechanistic analyses, this review will also briefly present corresponding strategies to enhance electrolyte/electrode interfaces through compositional modifications and structural designs. Overall, the comprehensive insights into electrolyte/electrode interfaces provided by this review can guide the future investigation of all-solid-state lithium batteries.
