The figure shown below is a phase diagram of the Lithium-Antimony binary system. According to the phase diagram, possible chemical reactions between Sb and Li are (1) 2Li+Sb Li2Sb or (2) 3Li + Sb Li3Sb. Answer the following questions. The atomic weight of antimony is 121.76. Assume that an antimony electrode is initially in delighted status (in other words, the Sb electrode initially does not contain lithium). a. (15 pts) Calculate the theoretical specific capacity (mAh/g) of the antimony electrode as a lithium-ion battery electrode concerning the reactions (1) and (2). b. (15 pts) Draw the theoretical discharge voltage vs. capacity plot of the Li-Sb system at 25 o C. Assume that the potential of reactions (1) and (2) is 0.92 V and 0.90 V (vs. Li/Li+), respectively. Assume that a voltage difference of 1.5 V between the Li electrode and the Sb electrode was measured at an open circuit. c. (10 pts) Estimate the theoretical energy storage (Wh/kg) of the Li-Sb system at 25 o C.
