英文摘要	The use of a rechargeable Li metal anode is one of the most favored choices for next-generation high energy density lithium batteries. Unfortunately, the growth of lithium dendrites during recharging hinders the practical application of Li metal anodes. Herein, we report a new biomimetic ionogel electrolyte with ant-nest architecture by the confinement of an ionic liquid within a chemically modified SiO2 scaffold for promoting the dendrite-free stripping/plating of Li anodes. The biomimetic ant-nest architecture not only has high ionic conductivity, but can also effectively restrain the Li dendrite growth by the spontaneous formation of a particle-rich protective layer on the lithium electrode during charge/discharge cycling. The solid-state full cells with LiNi1/3Mn1/3Co1/3O2 exhibit a very high energy density of ca. 390 W h kg(-1). The as-prepared Li/Li4Ti5O12 full cells present excellent cycling stability up to 3000 cycles with excellent Coulombic efficiencies of >99.8%. The present work opens a new route for the use of the biomimetic concept for designing a new ant-nest ionogel electrolyte for developing high energy density Li metal batteries with high stability.; National Key Research and Development Program of China "New Energy Project for Electric Vehicle'' [2016YFB0100204]; National Science Foundation of China [21373028, 51671003]; National Natural Science Foundation of China [U1564206]; Major achievements Transformation Project for Central University in Beijing; China Postdoctoral Science Foundation [2016M600012]; SCI(E); ARTICLE; 7; 1660-1667; 10
