Rechargeable batteries with lithium metal anodes exhibit higher energy densities than conventional lithium-ion batteries. Solid-state electrolytes (SSEs) provide the opportunity to unlock the full potential of lithium metal anodes and fundamentally eliminate safety concerns caused by flammable liquid electrolytes. Up to now, most studies on SSEs have been focused on enhancing the ionic conductivity and improving the interfacial stability. However, the electrolyte thickness, which has received less attention, also plays an important role in determining the energy density and electrochemical performance of all-solid-state lithium batteries (ASSLBs). Recognizing this, our review evaluates SSE studies beyond traditional factors and focuses on a thickness perspective. We systematically analyze the influence of the electrolyte thickness on the energy densities of ASSLB pouch cells, and highlight the strategies that dramatically reduce the thickness of SSE membranes without sacrificing their mechanical properties. Then, we discuss recent advances and challenges of ASSLBs based on high-voltage and high-capacity cathodes, as well as novel configurations such as bipolar and flexible ASSLBs. Finally, we provide perspectives and suggestions towards high energy-density ASSLBs for future commercialization.

降低高能锂电池用固态电解质膜的厚度

具有锂金属阳极的可充电电池表现出比常规锂离子电池更高的能量密度。固态电解质（SSE）提供了释放锂金属阳极全部潜能的机会，并从根本上消除了由易燃液体电解质引起的安全隐患。到目前为止，大多数对SSE的研究都集中在提高离子电导率和改善界面稳定性上。然而，电解质厚度受到了较少的关注，它在确定全固态锂电池（ASSLB）的能量密度和电化学性能方面也起着重要作用。认识到这一点，我们的评论评估了传统因素以外的SSE研究，并着重于厚度角度。我们系统地分析了电解质厚度对ASSLB袋式电池能量密度的影响，并重点介绍了在不牺牲其机械性能的情况下大幅减少SSE膜厚度的策略。然后，我们讨论了基于高压和高容量阴极的ASSLB的最新进展和挑战，以及诸如双极性和柔性ASSLB的新型配置。最后，我们为未来的商业化提供了高能量密度ASSLB的观点和建议。以及新颖的配置，例如双极和灵活的ASSLB。最后，我们为未来的商业化提供了高能量密度ASSLB的观点和建议。以及新颖的配置，例如双极和灵活的ASSLB。最后，我们为未来的商业化提供了高能量密度ASSLB的观点和建议。
