What are the advantages and disadvantages of ternary material lithium batteries?

Ternary lithium battery anode material structure Commonly used anode materials for commercial lithium batteries include carbon materials, lithium titanate, etc. This article uses typical anode graphite for analysis. The decay of the lithium battery capacity occurs for the first time in the formation stage, during this stage SEI will be formed on the surface of the negative electrode, consuming part of the lithium ions. Advantages of ternary materials for lithium batteries Because of their low price and stable performance, ternary materials are known as the preferred materials for lithium batteries, and lithium batteries with ternary materials as the positive electrode have many advantages. 1. The positive electrode is a ternary lithium battery material, and the negative electrode is a mixture of artificial graphite and other advanced negative electrode materials. 2. Laminated flexible packaging technology, this structure has uniform current collection, good heat dissipation, and improved battery rate performance. 3. The diaphragm treated with patented technology improves the safety of the ternary lithium battery body. The single battery and module have undergone safety evaluation tests such as drop, squeeze, acupuncture, hot box, overcharge and overdischarge, and meet the requirements of related batteries in my country Standard and regulatory requirements. The shortcomings of ternary material lithium batteries, poor safety and short cycle life are important shortcomings of ternary lithium batteries, especially safety performance, which has been an important factor that has restricted their large-scale assembly and large-scale integrated applications. A large number of actual tests have shown that it is difficult for ternary batteries with larger capacity to pass safety tests such as acupuncture and overcharge. This is also the reason why more manganese elements are generally introduced in large-capacity batteries, or even mixed with lithium manganate. The cycle life of 500 times is in the middle of the lithium battery, so the current important application field of the ternary lithium battery is consumer electronic products such as 3C digital.
