Inasolid-statebatteries, :inorganic, Improved safety (not flammable, no leakage, no thermal runaway, restrict dendrite formation) High tolerance to high temperature thus less safety protection/cooling systems are needed Improved energy density: It allows the replacement of conventional anodes with lithium metal (higher capacity), thinner cells, large ESW No separator membrane required Simpler cell/pack design Lower power density (for the moment) due to lower ionic conductivity of Solid electrolyte and resistance induced at electrode/electrolyte interface Requires different manufacturing processes than liquid Batteries High mechanical constraints in the cell More expensive Operation at low temperature may be challenging.
