What are the differences between lithium battery and lithium polymer battery charging methods?

Currently, there are two types of lithium batteries for mobile phones: lithium batteries and lithium polymer batteries. Generally speaking, the positive data of the two batteries are the same and both are lithium cobalt oxide (the ternary data and lithium iron phosphate are currently not mixed in mobile phone battery products). The important difference is that the lithium battery electrolyte is lithium hexafluorophosphate, lithium polymer battery The electrolyte is a solid polymer. Polymer batteries are basically Sony Ericsson batteries. Generally speaking, polymer batteries discharge more uniformly and have better safety performance, but the cost is higher. The charging principle of these two kinds of lithium batteries is basically the same. Now let us focus on the safety features of lithium batteries. Because the lithium battery itself is not overcharged for maintenance, which means that it is easy to overcharge and cause an explosion, so all battery manufacturers will choose the lithium battery circuit control chip to install inside the power supply, and the power will be cut off immediately after being overcharged . On the other hand, nickel-metal hydride batteries have little effect on overcharging by themselves, and as long as the temperature is within a safe range, there will be no accidents. The safe temperature of lithium is about 180 degrees. Beyond this temperature, there is a very simple explosion. So, how do you charge a newly purchased mobile phone battery? Because any lithium battery must be installed and fully tested before leaving the factory, this process is also equivalent to activation, so it can ensure that the correct lithium ion can be charged freely and there is no lattice collapse. Therefore, for ordinary consumers' hand batteries, it is a strictly tested activation process and does not need to be subjected to cardiac activation. The origin of the earliest three Internet broadcasts for the 12-hour charging theory. The earliest mobile phone battery is a nickel-metal hydride battery. For example, for Nokia 3310, the nickel-metal hydride battery should not be activated, and the battery itself has a recall effect. The user is required to charge to the fullest when in use, and then fully discharge (the voltage is changed from 1.2v to 1.0v), which prevents the recall effect. If the initial charging time is too short, the battery cannot be fully charged. A 1000 mAh battery may only charge to 900 mAh. Regardless of the efficiency of the battery, the battery life itself will still have a long and large impact. What happens when the same method is applied to lithium batteries? The crystal characteristics of lithium cobalt oxide are different from that of hydroxide. Nickel is more prone to lattice collapse than nickel hydroxide. Therefore, during the charging process, if you charge for too long, simply invalidate the space activity of the lithium cobalt oxide, and the charging will inevitably cause the temperature to rise. One is the data on the positive electrode, and this may be very dangerous. Because of this, we will definitely not run out of battery power during the process of using lithium batteries. After charging, lithium cobalt oxide will seriously fail and shorten the lifespan. The correct way is not to charge the battery before it runs out. The battery indicates that the charge is complete, and the power should be unplugged immediately. The most suitable method of charging with a mobile phone is to charge it offline when it is turned off, unplug it immediately when charging, and start charging again.
