What is a high-rate battery? How to charge a high rate of lithium-ion batteries? High-magnification battery means that the battery can be high-current discharge, the high-magnification charge and discharge resistance of the lithium ion battery is closely related to the mobility of the lithium ion in the electrode, the electrolyte and the interface, affecting the factors of the lithium ion migration speed affect the battery. High magnification charge and discharge performance. What is a high-rate battery? High-magnification battery can meet 100C discharge rate, continue 60C, widely used in special occasions such as large current discharge.
Suitable for high-power products such as drone, model aircraft, electric tools. Rate battery generally refers to a lithium-ion battery, a lithium-ion battery is a high-rate battery, important dependence on lithium ions move between the positive and negative poles. During the charge and discharge process, Lu + is embedded and unblocked between the two electrodes: in the rechargeable battery, Li + from the positive electrode, insertion of the negative electrode, the negative electrode is in a lithium state; during the discharge process, the opposite.
Generally used materials and lithium elements as electrodes. He is a representative of modern high-performance cells. Lithium-ion battery is divided into high rate batteries and lithium ion batteries.
Previously, the lithium-ion battery is used in mobile phones and laptops, which are often referred to as high-rate batteries, but the real high-magnification battery is rarely used in daily electronic products due to their high risk. The nature of the high-magnification polymer lithium ion battery has the characteristics of high current discharge performance, high platform, and cycle life. The discharge rate can satisfy 100C pulse rate, continue 60C, fast charging capacity up to 5C.
How to charge a high rate of lithium-ion batteries? First, the new battery is charged, to activate the new rate of lithium-ion battery, after a battery is placed, will enter the sleep state, at which time the capacity is below normal, the usage time is also shortened, to start. The activation method of the lithium-ion battery is very simple. After 3-5 normal charge and discharge cycles, the battery can be activated to restore its normal capacity.
Second, the old battery charging 1, the old battery refers to a battery that has been charged and discharged, not a scrapped battery. High-magnification lithium-ion battery life has nothing to do with the number of charge and discharge, he does not have a memory effect, regardless of how the charging method does not affect the number of charging cycles. So don't use the battery to charge when the battery is completely out of power, it is best to use a chargeable battery when charging, and the charging time is within 2-3 hours.
Of course, you have to fully charge it, not necessarily and shallow and shallow discharge. 2, the safety operating voltage of the charging voltage high-speed lithium ion battery is 2.8V to 4.
2V, lower or higher than this voltage range, and lithium ions become unstable in the battery. In order to ensure that the battery is within the security range, you have a special charger. These chargers will automatically adjust the charging mode according to the current state of the battery.
3, charging tool high-speed lithium ion battery charging should use special charger to ensure safety charging. When the charger works, he charges the battery with a constant current. With the new battery voltage, the charger will also add a charging voltage to speed up the charging speed.
When the battery reaches 4.2V cutoff, the battery will only be rushed to about 70% (not full). At this time, the charger will continue to charge the battery at a constant voltage, and gradually decrease, when the value is less than 0.
1a, he will stop charging when the battery voltage continues to rise. 4. Regular charging long-term high-speed lithium ion battery should be stored in a cool dry place.
Full-capacity battery will be damaged, and the battery that may be made will be destroyed and loses the function without electricity. In the stored procedure, every 3 to 6 months, to complete a charging cycle, you must make a battery calibration. Conclusion: With the development of science and technology, high-rate lithium-ion battery products have become a variety of high-speed electronic products.
High-speed lithium-ion battery can charge 300 ~ 500 times, if exceeded this number, the battery will not be used, of course, this is for reference only. High-magnification lithium-ion battery has nothing to do with the number of charging, and is related to the charge and discharge cycle, that is, the number of times from zero charge to complete charge. .
