　　Application prospects of 18650 battery 3.7v 3500mah

　　Advantages of 18650 battery 3.7v 3500mah

　　1. Good safety factor: The most important thing about battery car batteries is high safety. Lithium titanate has a high equilibrium potential difference and is not prone to lithium dendrites on the negative stage, so it has a good safety factor.

　　2. Excellent circulation properties: Because it is a zero-strain material, there is no structural change during the battery charging process, so it has very excellent circulation properties.

　　3. Can be charged and discharged quickly: The thermal diffusion coefficient of the lithium-ion battery in the lithium titanate crystal is 2×10-8cm-2/s, which is one order of magnitude larger than the negative grade of high-purity graphite. The battery can be charged quickly and the battery can be charged quickly. Capacity is an important indicator for evaluating the characteristics of battery vehicles.

　　4. The operating temperature range is -30°C~60°C: The ability to insert and remove lithium at low temperatures will be reduced, especially the insertion ability. When the lithium titanate negative stage is charged at -30°C, it will not work. Lithium dendrites are prone to cause short-circuit faults or cause the cathode to deteriorate. This is something that high-purity graphite cathodes cannot guarantee. Under normal environmental conditions, it can be charged and discharged quickly and is suitable for automotive applications.

　　5. Small self-discharge: the positive stage uses ordinary lithium manganese oxide batteries, and the negative stage uses 18650 battery 3.7v 3500mah. The volume remaining rate after 28 days of storage at 60 degrees is 88%, and the volume recovery rate is over 95%.

　　Disadvantages of 18650 battery 3.7v 3500mah

　　1. Compared with other types of lithium-ion battery power lithium batteries, its specific energy is slightly lower.

　　2. 18650 battery 3.7v 3500mah have always had the problem of inflation.

　　3. Compared with other types of lithium-ion battery power lithium batteries, the price is higher.

　　4. There are still differences in the consistency of rechargeable batteries. As the consistency of new rechargeable batteries improves, the difference in consistency of rechargeable batteries will gradually expand.

　　Application prospects of 18650 battery 3.7v 3500mah
