Not bad.
The advantages are: 1. High security;
2. Long service life, which can reach more than 2000 times;
3. Large capacity and no memory effect. Regardless of the battery condition, it can be charged and used at any time. There is no need to unload and recharge it first.
4. Green and eco-friendly. Lithium manganate batteries are generally considered to be free of heavy and rare metals, non-toxic and non-polluting;
5. Good performance at high temperatures. The thermal peak of lithium manganate can reach 350℃-500; ℃, while the thermal peak of some lithium batteries is only about 200℃.
Advantages of lithium manganate batteries
1. High safety
Lithium manganate has good safety performance. According to the investigation, during real acupuncture or short circuit experimentst, it was found that a small number of samples burned, but there was not a single explosion incident in the overcharge experiments, with a high-voltage charge far exceeding its own discharge voltage. several times, then there was an explosion. In fact, after the overcharge reaction of lithium manganate, its safety has been greatly improved compared with other lithium batteries.
2. Long life
We all know that the life of so-called long-life lead-acid batteries can only reach about 300 times, with a maximum of 500 times. . The lithium manganate battery has a lifespan of more than 2,000 times. The lifespan of lead-acid batteries of the same quality is generally about 2-3 years, while the theoretical lifespan of lithium-manganate batteries will reach 7-8 years when used under the same conditions.
3. Large capacity without memory effect
When the battery is lowOften used in conditions where it is fully charged but not fully discharged, the capacity will quickly fall below the rated capacity value. . This phenomenon is called memory effect. Nickel metal hydride and nickel cadmium batteries have memory, but lithium manganate batteries do not have this phenomenon and the battery capacity will not be reduced. Regardless of the battery condition, it can be charged and used at any time. There is no need to unload it and then recharge it. The volume of a lithium manganate battery with the same specifications and capacity is 2/3 that of a lead-acid battery, and its weight is 1/3 that of a lead-acid battery.
4. Green and environmentally friendly
Lithium manganate batteries are generally considered non-toxic and non-polluting because they do not contain any heavy metals or rare metals. The reason whyThe fact that lithium batteries are favored by the industry is mainly due to environmental protection considerations. As an important branch of lithium batteries, the environmental performance of lithium manganate is self-evident.
5. Good high temperature performance
It is understood that the thermal peak of lithium manganate can reach 350℃-500℃, while the thermal peak of some lithium batteries is only about 200℃. Therefore, lithium manganate has some advantages in high temperature performance!
Inevitably, lithium manganese batteries also have their own disadvantages: their low temperature performance is poor, and the preparation cost of lithium manganese materials and the manufacturing cost of batteries are relatively high.
