601525 lipo battery.Fast charging technology is fully popular! Will it damage the battery?

What is in front of people now may not be how fast the charging speed of mobile phones is. After all, Xiaomi has developed 100W fast charging, and 40W fast charging is also available everywhere. Wireless charging has already achieved 20W, and now even a thousand yuan All mobile phones are beginning to use fast charging technology. Under normal circumstances, the use of these once high-end technologies in thousand-yuan machines can only mean that their costs have been reduced, so these technologies can be popularized. As the number of users increases, there will be another problem. The chargers that everyone has used are basically 5V1A specifications, not to mention Apple. 1A chargers have been used for several generations, but in the era of fast charging, charging with various parameters Now that they have all the devices, consumers will inevitably have questions at this time. Will the parameters become larger, will it damage the battery? After all, the batteries of mobile phones today are not replaceable, unlike in the past. Here we will introduce several major directions of today’s fast charging technology. Nowadays, there are actually two main methods to improve the charging speed, which are also the two general directions today: 1. Increase the voltage. Increasing the voltage requires higher quality of the charger. The charger will generate a lot of heat during the charging process, so if the charging If the equipment does not meet the standards, it may be dangerous. 2. Increasing the current means lowering the voltage to increase the current. However, large current also has disadvantages. For example, it will accelerate the aging of the battery and bring certain safety hazards, and large current will also cause damage to the chemical substances inside the lithium battery. Irreversible loss, but it also has advantages, that is, low heat generation. It depends on the manufacturer how to balance the relationship. But fast charging technology all needs to meet three conditions, that is, the three indispensable links: charger, battery, and chargeIC. The fast charging technology that increases the current usually requires additional customization of the charging cable. Because the current is large and there are no certain standards, it will cause harm to the human body. For now, mobile phone fast charging technology is mainly divided into the following three categories: 1. VOOC technology, the core of which is low voltage and high current. 2. Qualcomm QuickCharge technology, its core is high voltage and low current. 3. MediaTek PumpExpressPlus technology allows the charger to determine the voltage based on current and can be dynamically adjusted. So in the final analysis, will this fast charging technology for mobile phones affect the life of the battery? In fact, you can think about combining the two directions mentioned above to increase the charging voltage or current to increase the charging speed. In fact, when the charging current becomes larger, the material on the surface of the negative electrode of the battery will rupture. This material is called a semipermeable membrane. It will rupture slightly, but the result is that the internal materials will react, so it will cause irreversible loss. However, increasing the voltage will also increase heat, which is also the biggest killer of lithium batteries and will reduce battery activity and capacity. However, there is no need to be pessimistic about this, or not use fast charging because of this, or even use slow charging on your fast-charging mobile phone. Let’s not talk about the life of the battery itself. In fact, many times if you use slow charging, you will also If the battery is damaged, after all, it cannot meet the standards for mobile phone charging. The IC chip will naturally have to make different adjustments. Therefore, the battery is inherently a consumable, and the lifespan of smartphones on the market today is very long. The lifespan is generally at least 500 charging cycles, as long as we can pay attention to develop correct charging habits, it is perfectly fine to use it for about two years. After all, lithium batteries have been around for many years, and the technology has been accumulated well, so they will not break down quickly. Fast charging technology is fully popular! It comes standard with a thousand-yuan phone, but will it damage the battery? Therefore, no matter which technology is used, it will cause certain damage to the battery, so it is not easy to draw a conclusion on which technology is better. It can only be said that everyone has different opinions, but these technologies will have a certain impact on mobile phone batteries. Compared with slow charging, you should make your own decision. I can’t stand slow charging anymore anyway. What about you?
