In lithium ion batteries, replacing graphite anode with lithium metal is one of the most promising ways to increase energy density. To avoid dendrite problems caused by lithium metal anode, many kinds of solid state electrolytes are reported. Garnet Li7La3Zr2O12 has high chemical and electrochemical stability with lithium metal, its shear moduli is also higher than most membrane materials, so it is one of the most promising solid state electrolyte materials. However, there are still dendrites penetrating under a small current density in Li7La3Zr2O12. This thesis is aiming to find possible controlling factors of critical current density.
