Aluminum-lithium alloys are well known in the aerospace industry as strong, light-weight materials for advanced aircraft structures. However, these alloys have also been considered as electrodes in Li-ion batteries. The standard reduction potentials for Al and Li are:

Al³⁺ + 3e^- Al V⁰ = -1.677 vs. NHE

Li⁺ + e^- Li V⁰ = -3.040 vs. NHE

Thus, in an electrochemical cell with Al metal and Li metal as the two electrodes, lithium will serve as the anode and aluminum the cathode, with the cathodic reaction written generally as:

Al + xLi⁺ +xe^- Li_xAl

Using the Al-Li phase diagram* to determine the phase evolution of the discharge, determine the expected discharge voltage profile if the reaction was performed at 150 ^oC. Make a sketch and label it.
