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.

5 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. High pressure is required to maintain electrode contact Electrochemical stability issues with some electrolytesSource: University of GenevaConventional liquid batteryAll- Solid -state batterySource: Argonne National Laboratory Solid -statebatterieshavebeendevelopedtoe nhancebatterysafety(notflammable,noleaka ge,nothermalrunaway,restrictdendritesfor mationetc.)
