The Greprow Blog said it best:

There are many kinds of anode materials for lithium-ion batteries. Depending on the cathode material, they can be divided into lithium cobaltate, lithium manganate, ternary materials, lithium iron phosphate, and lithium titanate.

A ternary lithium battery is a lithium battery that uses three metal oxides, nickel, cobalt, and manganese, as anode material. Since it combines the advantages of lithium cobaltate, lithium nickelate, and lithium manganate, the performance is superior to any of the above single anode materials. The experimental analysis indicates that the three different valence elements form a superlattice structure, and there are obvious synergistic effects between the three components, which makes the material more stable and the discharge platform is as high as 3.6V, so it is considered to be the most promising.

The current research on ternary materials mainly focuses on the preparation of precursors, the synthesis of materials, and the relationship between electrochemical properties and structure. Most of the transition metal elements Ni, Co, Mn exist in the +2, +3, +4. In the process of charging and discharging, the only electrochemical reactions are Ni2+/Ni4+ and Co3+/Co4+. Participation in the electrochemical reaction only serves to stabilize the structure of the material.

The commonly used synthesis methods in the industry include a high-temperature solid-phase, co-precipitation, sol-gel, hydrothermal synthesis, and combustion. By changing the molar ratio of the three materials in a ternary lithium battery within a certain range and adding the corresponding additives (binder, conductor, fluid collector, etc.)
