The recent discovery of highly conductive solid-state electrolytes (SSEs) has led to tremendous progress in the development of all-solid-state batteries (ASSBs). Though promising, they still face barriers that limit their practical application, such as poor interfacial stability, scalability challenges and production safety. Additionally, efforts to develop sustainable manufacturing of lithium ion batteries are still lacking, with no prevailing strategy developed yet to handle recyclability of ASSBs. To date, most SSE research has been largely focused on the discovery of novel electrolytes. Recent review articles have extensively examined a broad spectrum of these SSEs using evaluation factors such as conductivity and chemical stability. Recognizing this, in this Review we seek to evaluate SSEs beyond conventional factors and offer a perspective on various bulk, interface and nanoscale phenomena that require urgent attention within the scientific community. We provide a realistic assessment of the current state-of-the-art characterization techniques and evaluate future full cell ASSB prototyping strategies. We hope to offer rational solutions to overcome some major fundamental obstacles faced by the ASSB community, as well as potential strategies toward a sustainable ASSB recycling model.

高导电性固态电解质（SSE）的最新发现已导致全固态电池（ASSB）的开发取得了巨大进展。尽管前景广阔，但它们仍然面临限制其实际应用的障碍，例如不良的界面稳定性，可扩展性挑战和生产安全性。另外，仍缺乏开发可持续发展的锂离子电池制造的努力，尚未开发出用于处理ASSB的可回收性的主流策略。迄今为止，大多数SSE研究都集中在发现新型电解质上。最近的评论文章使用诸如电导率和化学稳定性之类的评估因素广泛地检查了这些SSE的广泛范围。认识到这一点 在本综述中，我们寻求评估常规因素以外的SSE，并就需要科学界紧急关注的各种体积，界面和纳米尺度现象提供一个观点。我们提供对当前最先进的表征技术的现实评估，并评估未来的全细胞ASSB原型开发策略。我们希望提供合理的解决方案，以克服ASSB社区面临的一些主要基本障碍以及建立可持续ASSB回收模型的潜在策略。
