Help you analyze which is better between lithium manganate battery and ternary lithium ion battery

Professional lithium battery manufacturers can help you analyze which is better, lithium manganate battery and ternary lithium ion battery? Lithium manganate battery and ternary lithium ion battery, as members of the lithium battery family, have their own advantages and disadvantages. In ternary lithium, lithium manganese acid and lithium iron phosphate three-power lithium battery systems, lithium manganese acid has obvious price advantages. With the increase of ternary materials in the field of power batteries, lithium manganate gradually exceeds the market share of lithium iron phosphate due to its high energy density.

1. Contrast from the capacity density
 
Lithium manganese acid battery has the advantages of good performance, convenient preparation and low cost. The disadvantage is that the solubility of manganese leads to poor high temperature performance and cycle performance. Through analysis of doped aluminum and sintering and granulation by professional lithium battery manufacturers, high-temperature performance and cycle performance have been greatly improved, which basically meets the actual use. In general, lithium manganese oxide batteries have low cost, strong stability, strong low-temperature performance, poor high-temperature performance, and a slightly faster decay rate.
 
The ternary lithium ion battery has high energy density, and its cycle performance is better than that of ordinary lithium borate batteries. At present, with the continuous improvement of the formula and structure, the nominal voltage of the battery has reached 3.7V, and the capacity has reached or exceeded the level of the lithium diamond battery. Professional lithium battery manufacturers analyze that ternary material power lithium batteries mainly include nickel diamond lithium aluminate batteries, lithium nickel diamond manganese batteries, and other high-temperature structures that are unstable, leading to poor safe high temperatures and high pH values, which can easily expand a single gas. Cause failure, the cost is not low under current conditions.

2. Contrast from the material structure

Professional lithium battery manufacturers believe that the spinel structure of lithium manganate lithium batteries and its two similar characteristics are very obvious, that is, both advantages and disadvantages are very prominent. Its advantages are: low temperature resistance, good multiplication performance, and relatively easy preparation. The disadvantages are: the material itself is unstable and needs to be mixed with other materials, with poor high temperature performance, poor cycle performance, and fast attenuation. These shortcomings of lithium manganate are due to the properties of manganese. However, due to the extensive supply of manganese, it has a significant cost advantage

The advantages of ternary lithium-ion batteries are: small size, high capacity density, low temperature resistance, and good cycle performance. They are the mainstream of new energy passenger vehicles. Disadvantages: poor thermal stability, decomposition occurs at a high temperature of 250-300 ℃, and the chemical reactions of the three lithium materials are particularly strong. Once oxygen molecules are released, they will burn rapidly under the action of high-temperature electrolyte, and then deflagration.

Third, compare and analyze two kinds of lithium batteries from other aspects
 
Lithium manganese oxide is one of the promising anode materials for lithium-ion batteries. Compared with traditional anode materials, professional lithium battery manufacturers analyze rich resources such as lithium cobalt oxide and lithium manganate, which are low in cost, pollution-free, and safe. It is an ideal cathode material for power batteries, but its poor blood circulation and electrochemical stability greatly limit its industrialization.
 
There are many types of cathode materials for ternary lithium-ion batteries, including lithium cobalt acid, lithium manganese acid, lithium nickel acid, lithium ternary materials, lithium iron phosphate, and so on. This ternary material combines the advantages of lithium cobalt acid, lithium nickel acid and lithium manganese acid, and has a certain practical value

Professional lithium battery manufacturers believe that if lithium manganese acid batteries can maintain their original advantages, and through technological innovation, increase the number of cycles, increase capacity, and improve high and low temperature performance, although it does not have obvious advantages compared with ternary lithium ion batteries, it has The new energy market segment will also be able to occupy a place.
