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. (C) 2020 Elsevier Ltd. All rights reserved.
