Abstract
A nickel-free and cobalt-free cathode material for a lithium (Li) battery is provided. The cathode material includes, LiAlFeMnZnO, wherein a, x, y, z, and δ are in the following ranges: 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. In various embodiments, the present invention provides an improved Co-free/Ni-free Li-ion battery (LIB) cathode that exhibits good thermal stability and is capable of realizing a high cell voltage and specific capacity comparable to, or exceeding, currently known Li(NiCoMn)Ocathodes. The novel cathode chemistry in accordance with the embodiments of the present invention eliminates any potential cobalt supply issues and lowers the overall cost of the battery.
