Question

between aluminium
ions and copper ions which first emulated in anode​

Answer 1

Explanation:

Two criterias

1: electronic conductivity

2: Potential stability

For LIB the working potential for anode is ~0.5 to 2.5 and for cathode till ~3-4.7. So for anode Cu (0.337V wrt H) is selected as the oxidation potential of Cu ~2.7 wrt Li (3.045 V), so stable for anode.

Similarly for cathode, Al (1.662V wrt H) is selected as oxidation potential wrt Li is ~4.7. So stable for cathode.

These are for half cells, where one use Pure Li as anode. If LTO or another anode is used, conditions may vary.
