Nickel and cobalt-free cathode for lithium-ion batteries and method of manufacture

A lithium (Li)-ion battery (LIB) comprising:

• a cathode composed of a cathode material comprising LiaAl1-x-y-z FexMnyZnzO2- δ, wherein a, x, y, z, and δ are in a range of 0.95 ≤ a ≤ 1.2;
• 0 ≤ x ≤ 0.3;
• 0 ≤ y ≤ 0.3;
• 0 ≤ z ≤ 0.3;
• 0.5 ≤ x + y + z ≤ 0.99;
• 0 ≤ δ ≤ 0.1.
• an anode;
• and
• an electrolyte positioned between the anode and the cathode.

A method for synthesizing a cathode material for a cathode of a lithium (Li)-ion battery, the method comprising:

• synthesizing one or more precursors comprising two or more transition metals selected from Al, Mn, Fe and Zn in a predetermined ratio;
• preparing one or more Li composites;
• mixing the one or more precursors with the one or more Li composites;
• and calcinating the mixture of the one or more precursors with the one or more Li composites to synthesize a cathode material comprising LiaAl1-x-y-z FexMnyZnzO2- δ, wherein a, x, y, z, and δ are in a range of 0.95 ≤ a ≤ 1.2;
• 0 ≤ x ≤ 0.3;
• 0 ≤ y ≤ 0.3;
• 0 ≤ z ≤ 0.3;
• 0.5 ≤ x + y + z ≤ 0.99;
• 0 ≤ δ ≤ 0.1.
