Lithium Manganese Dioxide Battery Advantages

From:CTECHI GROUP Limited     Release time:2018-10-24

Overview:Lithium manganese dioxide battery advantages are good at performance, easy preparation of production with low cost. The disadvantage is that the dissolution of manganese leads to poor high temperature performance and cycling performance. By doping aluminum and sintering granulation, the high temperature performance and cycling induction are greatly improved, which can basically meet the actual use. Generally speaking, lithium manganate batteries have low cost, strong low temperature stability, poor high temperature performance and slightly faster decay.

The cathode material with low cost, good safety and low temperature performance, but its material itself is not very stable, easy to decompose and produce gas, so it is often used in combination with other materials to reduce the cost of the battery, but its cycle life decays faster, prone to bulge, poor high temperature performance, relatively short life, mainly used for The nominal voltage of large and medium sized batteries and power batteries is 3.7V.

There are three kinds of lithium manganese dioxide battery:

1. Layered lithium manganese oxide LiMnO2, theoretical capacity 285mA. H/g, voltage platform 4V. Layered structure is difficult to synthesize, unstable, easy to form Li2Mn2O4 spinel structure and lead to voltage platform decline, poor stability, irreversible capacity decay and so on.

2. High voltage spinel lithium manganese oxide LiMn2O4, theoretical capacity 148mA. H/g, voltage platform 4.15. The high temperature performance is poor, and the capacity attenuation is serious above 55 C. Li2Mn2O4 spinel structure is easy to be formed, which leads to the decrease of voltage plateau, poor stability, irreversible capacity decay and so on. Lithium manganese oxide is currently used in industry.

3. Spinel lithium manganate Li2Mn2O4, low voltage (3V), low capacity, poor circulation, are all studying how to avoid this kind of thing.

In order to solve the defect of layered lithium manganate, the ternary material LiNiCoMnO2 (LiNiCoAlO2) was invented by doping metal elements. It takes into account the high capacity, high voltage, high safety of lithium manganate, the good cycle of lithium cobalt and the difficulty of synthesis of lithium manganate and lithium nickelate. The instability and high cost of lithium cobaltate become the mainstream cathode materials. The theoretical capacity is 280mA. H/g, and the voltage is 2.7~4.2. Now the actual capacity is about 160mA h/g.

In the next few years, the current three yuan will basically be eliminated after three years, with high nickel and NCA playing the leading role. 10 years later, it is estimated that the all three yuan will be eliminated, and a new battery system will replace the three yuan.
