Abstract
The spinel based LiNi0.5Mn1.5O4 cathode material shows noteworthy advantages despite its inherent disadvantages. To overcome the weaknesses they have, they are challenged to get superior materials. This was carried out on the LiNi0.5Mn1.5O4 cathode material synthesized by doped vanadium metal elements into Nickel using the solid-state method, emphasizing the specific composition LiNi0.5-xVxMn1.5O4 (x=0.05) (y = 0.05), and sintering results at 600°C produces the expected single-phase structure in the Fd-3m space group. XRD analysis revealed the characteristic octahedral crystal structure of spinel type. SEM scanning showed non-uniform grain sizes (<10 □ m), indicating the possibility of grain coalescence caused by the sintering process. Additionally, irregular pore sizes were observed, potentially affecting conductivity. The activation energy obtained using Impedance Spectroscopy shows that all the prepared cathode materials are classified as semiconductors with an activation energy of about 0.13 eV, indicating good conductivity of the cathode materials.
