People often have a misunderstanding when charging: keeping full power status is the best. Perhaps for obsessive-compulsive disorder, it will have his life from 100% to 99%, but it is actually remained that the phone is maintained in the charging state is not a recommended behavior, especially after the device is full. Continue to charge, the mobile phone battery can really can't suffer such a toss.
Lithium batteries are not universal, there are many elders who will always tell you when you get the first mobile phone, and new mobile phones must first complete the discharge, then charge for 12 hours, then completely discharge, need to repeat 3 times. When you are stupid, you must be done in accordance with the elders, but you can actually use the smartphones of the lithium battery early no longer need such a troublesome battery maintenance process. The multi-discharge charging process is required is a nickel-hydrogen battery.
This battery has strong memory, repeated charging and discharging process is also to make the nickel-hydrogen battery to achieve maximum charging upper limit. Nowadays, mobile phones use lithium batteries, there is no need to repeat such complex battery memory processes. So, will the lithium battery keep the highest power limit? The answer is inevitable.
Although the lithium battery is scaled, it is not avoided during the multi-battery cycle charge. This loss is formed by the accumulation of the month, and the cause of the loss is except for normal charging. Charge is the culprit.
How to understand the phenomenon of preparation is actually very well understood, that is, the mobile phone continues to charge the mobile phone battery in the case of displaying power, and then we say that the mobile phone is overcharged. Continuing charging in the case where the battery is fully charged, causing the structural changes in the positive electrode material, causing capacity loss, and its disconnection oxygen and electrolyte will have severe chemical reactions, the worst result is naturally an explosion. Cases in the mobile phone explosion during real life.
For example, Xinhua Net reported on March 4, 2015, a 23-year-old girl charging mobile phone was burnt, and the Shanxi Evening News also reported that the 18-year-old teenager is playing mobile phone when charging mobile phones on June 15, 2015. The cause of these tragers can be attributed to the battery itself is damaged, the charger does not have IC protection, the power supply itself also has quality problems, etc. When the current is constantly input after the charging is completed, because the capacitance of the battery has reached the upper limit, most of the current is converted to thermal energy consumption, so that the battery begins to heat.
General sense also tells us that the best storage method is warm and dry, whether the nickel-hydrogen battery or lithium battery is true. When excessive occurs, there is no doubt that the current transformation of the current will exist in large quantities, resulting in the reaction of the lithium battery positive electrolyte, and consumes the maximum capacity of the lithium battery. When the heat is accumulated to a certain extent, fire, explosion such an incident It is possible to happen.
In the face of such a low security, natural mobile phone manufacturers and charger manufacturers will not sit. After all, when the user has a security problem, it must be them, so there is a lot of attention when charging the mobile phone, especially if the mobile phone and charger charging in the USB port now.
