The advantages of manganic acid tank are good rate performance, easy preparation and low cost. The disadvantage is that the high temperature performance and cycling performance are poor due to the dissolution of manganese, and the high temperature performance and cycling have been greatly improved by doping aluminum and sintering granulation, which can basically meet the actual use. In general, lithium manganate batteries have low cost, strong stability, strong low temperature, poor high temperature performance, and slightly faster attenuation.
There are three types of silver manganate:
(1) Layered lithium manganate LiMnO2, theoretical capacity 285mA-h/g, voltage platform 4V. Laminar structure is difficult to synthesize and unstable, and it is easy to generate Li2Mn204 spinel structure, which leads to voltage plateau decline, poor stability, and irreversible capacity decay.
(2) High voltage spinel lithium manganate LiMn204, theoretical capacity 148mA-h/g, voltage platform 4.15. High temperature performance is poor, capacity attenuation is serious above 55℃. It is also easy to form Li2Mn204 spinel structure, resulting in voltage plateau decline, poor stability, and irreversible capacity attenuation. This is what the industrial manganate carp currently uses.
(3) Spinel lithium manganate Li2Mn2O4, low voltage (3V), low passenger volume, poor circulation, are studying how to avoid this kind of thing. Ternary: In order to solve the defects of layered lithium manganate, the method of doping metal elements, invented Ni, Co (Al) to replace the strong terpolymer LiNiCoMnO2 (LiNiCoAlO2), taking into account the high capacity and high voltage buried nickel acid, the high voltage and high safety of lithium manganate, and the good cycling of lithium burrow acid. At the same time, it has overcome the shortcomings of difficult and unstable synthesis of lithium manganate and high cost of lithium boring acid, and has become the mainstream cathode material. The theoretical capacity is 280mA-h/g, the voltage is 2.7~4.2, and the actual capacity is about 160mA-h/g.
