What Are The Types And Characteristics Of Common Lithium Batteries?

With the increasing use of lithium batteries in the market, many products have been replaced by lithium batteries. Compared with ordinary lead-acid batteries, lithium batteries have the advantages of long life, no pollution, energy-saving and lightweight. So, what are the types of lithium batteries? Li-Ion Battery Energy Storage System Supplier is here to give you science.

Lithium manganate, as a lithium battery material with a long history of use, has high safety, especially strong overcharge resistance, which is a major advantage. Due to the good structural stability of lithium manganese oxide, the amount of positive electrode material need not exceed that of the negative electrode when designing the battery cell. In this way, the number of active lithium ions in the entire system is not large, and after the negative electrode is full, there will not be too many lithium ions stored in the positive electrode. Even if an overcharge situation occurs, a large number of lithium ions will not deposit on the negative electrode to form crystals. Therefore, the overcharge resistance of lithium manganese oxide is good among common materials.

The advantages of Lithium Iron Phosphate Battery is mainly reflected in safety and cycle life. The main determinant comes from the olivine structure of lithium iron phosphate. This structure, on the one hand, leads to lower ion diffusion capacity of lithium iron phosphate, on the other hand, it also has better high-temperature stability and good cycle performance.

The disadvantages of lithium iron phosphate are also obvious, low energy density, poor consistency and poor low-temperature performance. The low energy density is determined by the chemical nature of the material itself. A lithium iron phosphate macromolecule can only accommodate one lithium-ion.

Consistency, especially batch stability is not only related to production management level, but also to its own chemical properties. Lithium iron phosphate is one of the more difficult to prepare in the positive electrode materials of various lithium batteries. The high difficulty of the consistency and uniformity of this chemical reaction also brings another problem. The iron element and the iron ion impurities in the lithium iron phosphate material always exist, which brings hidden danger to the battery.

The ternary lithium cathode material combines the advantages of LiCoO2, LiNiO2 and LiMnO2 materials form a synergistic effect within the same cell and take into account the three requirements of material structure stability, activity and lower cost. One of the cathode materials with higher energy density. Its low-temperature effect is also significantly better than lithium iron phosphate batteries.

Among the three elements, the higher the content of Ni, the higher the energy density of the cell, and the lower the safety of the cell. In practical applications, the ratio of the three materials in the cell has been changing with time. People's pursuit of energy density is getting higher and higher, so the proportion of Ni is getting higher and higher.
