摘要
The ever-increasing energy density of the Li-ion battery calls for utilization of high-capacity cathodes and anodes, which tend to be more reactive and thus bring serious safety concern. Under such context, the solid-state Li battery becomes a hotspot because of its potential in the breakthrough of energy density as well as the avoidance of uncontrollable chemical reactions. Recently, many review and perspective papers appear, addressing the urgency of improving solid-electrolytes’ ionic conductivity and constructing stable conductive interfaces between electrolyte and electrode with respect to available electrolytes, including polymers, nitrides, sulfides, and oxides. Nevertheless, each type of electrolyte has its own distinctive problems, which is worthwhile specifically elaborating in order to find effective solutions. Therefore, here, we present our viewpoints on the key issues related to the garnet electrolytes and relevant batteries, which have not ever been dedicatedly addressed previously. On the basis of our recent progress, together with others reported in the literature, we expect that the solid garnet batteries are promising for application if the best use is made of garnet advantages and disadvantages are bypassed.
