How to make ternary batteries safe to use?


The ternary lithium battery is a ternary lithium battery because its positive electrode material uses a ternary polymer containing three metal elements of nickel, cobalt, and manganese (or aluminum).

The ternary of the ternary lithium battery refers to the three elements of nickel (Ni) and cobalt (Co) manganese (Mn). Among these three elements, nickel and cobalt are active metals, and manganese does not participate in the electrochemical reaction.

Generally speaking, the higher the content of active metal components, the greater the battery capacity, but when the content of Ni is too high, it will cause Ni2+ to occupy the position of Li+, which will intensify the mixing of cations, resulting in a decrease in capacity.

Co is also an active metal, but it can inhibit the mixing of cations, thereby stabilizing the layered structure of the material. As an inactive metal, Mn mainly plays a role in stabilizing the reaction and improving its safety.


The nickel-cobalt-manganese ternary material has the formula of LiNixCoyMnzO2, where x+y+z=1.
Positive electrode materials of ternary lithium batteries can have different ratios of nickel, cobalt, and manganese within a specific range. Its performance varies with the percentage of nickel, cobalt, and manganese.

Ternary cathode materials have advantages in battery-specific energy, specific power, high rate charging, low-temperature performance, etc., and ternary lithium batteries will also have better cycle performance. 

Additionally, lithium-ion ternary batteries will be used to their full potential from the perspective of adaptation policy since future energy density requirements will be higher. 

Conclusion

Due to the subordinate phrase and current battery management technology, ternary lithium batteries are naturally safe.

If the standard procedures and methods are followed when using and charging lithium batteries, there shouldn’t be too many issues.
