High-dense garnet electrolytes have sufficient mechanical strength and ion transference number of unity, through which blocking of Li penetration is expected. Nevertheless, the situation of Li growth through the solid garnet electrolyte is even worse than that in the case of liquid electrolyte. Many investigations have been carried out in terms of mechanism analysis and solution exploration. In this review, we classify the relevant research and point out the crucial factors that influence Li penetration across the solid electrolyte. The fundamental mechanism is summarized and the useful methods to relieve such problems are addressed. Whether or not the fundamental solution exists is answered and how to deal with such critical issue is suggested.

高密度石榴石电解质具有足够的机械强度和统一的离子转移数，可以期望通过其阻断锂渗透。然而，通过固体石榴石电解质的锂生长情况甚至比液体电解质的情况更糟。在机理分析和解决方案探索方面已经进行了许多研究。在这篇综述中，我们对相关研究进行了分类，并指出了影响锂穿过固体电解质渗透的关键因素。总结了基本机制，并提出了解决此类问题的有用方法。回答了是否存在根本解决方案，并提出了如何处理此类关键问题的建议。
