What are the reasons for high-quality ternary lithium-ion batteries for portable outdoor power supplies

First of all, let's talk about what a ternary lithium ion battery is: it refers to a lithium ion secondary battery that uses three transition metal oxides of nickel, cobalt and manganese as the positive electrode material. It fully integrates the good cycle performance of lithium cobalt oxide ions, the high specific capacity of lithium nickel oxide ions, and the high safety and low cost of lithium manganate ions. It uses molecular level mixing, doping, coating and surface modification, etc. The method is to synthesize a composite lithium ion intercalation oxide with multi-element synergy such as nickel, cobalt and manganese. It is a kind of lithium rechargeable battery that is widely researched and applied. The advantages of high-quality ternary lithium-ion batteries: Co3+: Reduce cation mixed space, stabilize the layered structure of the material, reduce the impedance value, increase the conductivity, and improve the cycle and rate performance. Ni2+: can increase the capacity of the material (increase the volume energy density of the material). Mn4+: Not only can reduce the cost of materials, but also can improve the safety and stability of the materials. High energy density is the biggest advantage of ternary lithium-ion batteries, and the voltage platform is an important indicator of battery energy density, which determines the basic efficiency and cost of the battery. The higher the voltage platform, the larger the specific capacity, so the same volume, weight, and even The same ampere-hour battery, the ternary material lithium-ion battery with a higher voltage platform has a longer battery life. The discharge voltage platform of the single ternary lithium ion battery is as high as 3.7V, the lithium iron phosphate ion is 3.2V, and the lithium titanate ion is only 2.3V. Therefore, from the perspective of energy density, the ternary lithium ion battery is higher than the lithium iron phosphate ion , Lithium manganate ion or lithium titanate ion has absolute advantages. In general, the portable outdoor power supply of ternary lithium-ion battery is more balanced in terms of capacity and safety, and it is a power supply with excellent comprehensive performance.
