Solid-state battery electrolytes overcome the traditional safety concerns of leakage and unimpeded dendrite growth in liquid state electrolytes and can be used with a lithium metal anode . The high capacity of lithium metal anodes , combined with stacking efficiency due to structural integrity of the solid-state electrolytes means that high volumetric and specific energy densities can be achieved in solid-state batteries. Inorganic solid-state electrolytes show significantly higher ionic conductivities compared to solid polymer electrolytes , making all solid-state batteries with inorganic solid electrolytes a promising nextgeneration technology for energy storage.
