Advantages, disadvantages and lifespan of lithium batteries

The advantages of lithium batteries are: lithium batteries have a long life, with a cycle life of more than 2000 times. Under the same conditions, lithium batteries can be used for 7 to 8 years. 2. Safe use. Lithium batteries have undergone strict safety tests and will not explode even in traffic accidents. 3. Fast charging. Use a dedicated charger to charge the battery for 40 minutes at a temperature of 1.5c. 4. The lithium battery is resistant to high temperatures, and the hot air value of the lithium battery can reach 350 to 500 degrees Celsius. The lithium battery has a large capacity. 6. The lithium battery has no memory effect. 7. Lithium batteries are environmentally friendly, non-toxic, non-polluting, have a wide range of raw materials, and are low in price. 2. The disadvantages of lithium batteries are as follows: The vibration density of the positive electrode of lithium batteries is relatively small, generally between 0.8 and 1.3. Large volume. 2. Poor conductivity, slow diffusion of lithium ions, and low actual capacity during high-power charging and discharging. 3. Low temperature performance of lithium battery. 4. The life of a single lithium battery is longer, about 2000 times, while the life of a lithium battery is shorter, about 500 times. How long can a lithium battery last? The life of a lithium battery is not calculated in years, but in cycles. The life of a lithium battery is 500 times, not the number of recharges, but a cycle of charging and discharging. Now mobile phones use lithium batteries, and the lithium battery cycle is 500 times the most, that is, the cycle from 0 to 100 (100 years is a cycle of cycles), when the mobile phone battery after 500 times is already weak, the internal resistance of the battery Newly added, the activity of internal chemical elements declines, and the stage of rapid consumption. You have all experienced this: a very old cell phone is fully charged and then turned off after a call. Extended information: The charging cycle refers to the battery from full to empty, and then from empty to full, which is different from charging. For example, a lithium battery uses half of its power on the first day and then recharges it. If this is the case the next day, half of the fee will be charged and the price will be reduced twice. This is a cycle, not two. Therefore, it may take several recharges to complete a cycle. After each charge, the capacity of the battery will drop a little. However, this drop is so small that a high-quality battery can still maintain 80% of its original capacity after multiple charges, and many lithium-ion products will continue to be used after two to three years.
