与传统的液体电解质电池相比，全固态电池（ASSB）具有更高的安全性和更宽的工作温度范围，因此被认为是一种非常有前途的储能技术。虽然已经发现了离子电导率与液体电解质相当的固体电解质，但制造具有高面积容量且可以在合理的电流密度下循环的固态全电池仍然是一个主要挑战。为了克服这些挑战，除了与锂金属阳极（包括无阳极电池设计）相关的显着体积变化引起的机械方面之外，还需要对阴极复合材料内控制离子和电子传输限制的现象进行定量和深入的了解。这种理解可以从本文描述的适当的电化学测量中获得。在本次审查中，我们力求强调这些现有挑战的解决方案，并提出未来工作的几个方向。(c) 2022 年由爱思唯尔有限公司出版。
All-solid-state batteries (ASSBs) have been promoted as a highly promising energy storage technology due to the prospects of improved safety and a wider operating temperature range compared to their conventional liquid electrolyte-based counterparts. While solid electrolytes with ionic conductivities comparable to liquid electrolytes have been discovered, fabricating solid-state full cells with high areal capacities that can cycle at reasonable current densities remains a principal challenge. To overcome these challenges, a quantitative and in-depth understanding of the phenomena governing ionic and electronic transport limitations within the cathode composite, in addition to mechanical aspects arising from significant volume changes associated with Li metal anodes (including anode-less cell designs) are needed. Such understanding can be obtained from proper electrochemical measurements described herein. In this review we seek to highlight solutions to these existing challenges and several directions for future work are proposed.(c) 2022 Published by Elsevier Ltd.
