1, with high security.
Lithium manganate has good safety performance. According to the investigation, in actual operation, it was found that a small number of samples burned, but no explosion occurred. However, in the overcharge experiment, an explosion occurred when a high voltage several times higher than its own discharge voltage was used. In fact, after overcharge, the safety of lithium manganate has been greatly improved compared with other lithium batteries.
2. Long cycle life
As we all know, the cycle life of the so-called long-life lead-acid battery can only reach about 300 times, up to 500 times. The cycle life of lithium manganate battery can reach more than 2000 times. The electrical life of lead-acid with the same quality is generally about 2-3 years, while the theoretical life of lithium manganate battery will reach 7-8 years under the same conditions.
3, large capacity without memory effect
When the battery is always fully charged and not fully discharged, the capacity will soon drop below the rated capacity. This phenomenon is called memory effect. For example, Ni-MH and Ni-Cd batteries have memories, while lithium manganate batteries do not, so the battery capacity will not decrease. No matter what state the battery is in, it can be used whenever it is charged, and there is no need to discharge before charging. The volume of lithium manganate battery with the same specification and capacity is 2/3 of that of lead-acid battery and its weight is 1/3 of that of lead-acid battery.
4. Environmental protection
Lithium manganate batteries are generally considered non-toxic and pollution-free, and do not contain any heavy metals and rare metals. The reason why lithium batteries are favored by the industry is mainly due to environmental review. As an important branch of lithium battery, lithium manganate is self-evident.
5, good high temperature performance
It is understood that the peak value of lithium manganate can reach 350℃-500℃, while the peak value of some lithium batteries is only about 200℃. Therefore, lithium manganate has certain advantages in high temperature performance!
Inevitably, lithium manganate battery also has its own shortcomings: poor low-temperature performance, relatively high preparation cost of lithium manganate material and battery manufacturing cost.
