Introduction to lithium manganese aluminate battery

There are still many problems in ordinary lithium manganese acid because of its structure, such as: In 2012, Rebar company began to study the improvement of ordinary lithium manganese acid, doped aluminum in the original ordinary lithium manganese acid, so that the original unstable structure of Mn3+ modified into a stable structure of Mn4+, completely solve some of the drawbacks of ordinary lithium manganese acid.

                 Charge and discharge curve of lithium manganese aluminate of Liba Company

                    Charge and discharge curve of lithium manganese aluminate of NMC

                         Charge and discharge curve of LiFePO4

As can be seen from the discharge curves of the above three lithium batteries,

1. Liba lithium manganese aluminate can reach about 95% at 3.6V discharge platform (the green line is the discharge platform at the focus of x axis and Y axis).

2. The charge-discharge curve of teri is also 3.6V discharge platform ((on the focus of x axis and Y axis, the green line is discharge platform), which is about 55%.

3, charge and discharge curve of lithium iron phosphate, its discharge platform voltage is 3.0V discharge platform (x axis and Y axis focus, the green line is the discharge platform) can reach about 95%.

By comparing the discharge rate is highest is Liba manganese acid lithium aluminum, lithium iron phosphate discharge rate is high, three discharge rate is very low, that is to say, the high rate discharge voltage of three serious fell, the residual strength is very difficult to put out at the end of the discharge time, basic can achieve test ability, but the efficiency is relatively low, so they all have their own advantages and disadvantages.
