Is the lithium manganate battery good?

The advantage of lithium manganate is good rate performance, easier preparation and lower cost. The disadvantage is that the high temperature performance and cycle performance are poor due to the dissolution of manganese. Through doping with aluminum and sintering granulation, the high temperature performance and cycle performance have been greatly improved, which can basically meet the actual use. In general, lithium manganate batteries have low cost, strong stability and strong low temperature performance, poor high temperature performance, and slightly faster attenuation. There are three kinds of lithium manganate: 1. Layered lithium manganate LiMnO2, theoretical capacity 285mAh/g, voltage platform 4V. The layered structure is difficult to synthesize and unstable, and it is easy to generate Li2Mn2O4 spinel structure, which leads to a drop in voltage plateau, poor stability, and irreversible capacity degradation. 2. High voltage spinel lithium manganese oxide LiMn2O4, theoretical capacity 148mAh/g, voltage platform 4.15. Poor high temperature performance, serious capacity degradation above 55°C. It is also easy to generate Li2Mn2O4 spinel structure, resulting in a drop in voltage plateau, poor stability, and irreversible capacity degradation. Lithium manganate is currently used in industry. 3. Spinel lithium manganese oxide Li2Mn2O4, low voltage (3V), low capacity, poor circulation, are studying how to guard against such things.
