The biaxial modulus and the coefficient of thermal expansion for representative cathodes and electrolytes. Each of these materials are representative of a broader class of solid electrolytes or electrodes: LLZTO is representative of oxide electrolytes , Li 10 GeP 2 S 12 (LGPS) is representative of crystalline sulfide electrolytes, Li 1+x Al x Ti 2-x (PO 4 ) 3 (LATP) is representative of LISICON electrolytes, and Nickel Manganese Cobalt Oxide (NMC) or Lithium Iron Phosphate (LFP) are representative of various classes of cathodes .
