How to correctly understand the lithium-ion battery overtime?

People often have a misunderstanding when charging: keeping full power status is the best. Perhaps on obsessive-compulsive dismissions, it will have his life from 100% to 99%, but it is actually remained that the phone is maintained in the state of charge is not a recommended behavior, especially after the device is full. Continuous charging, mobile phone batteries can really can't suffer so toss.

Lithium-ion batteries are not universal, many elders will always tell you when you get the first mobile phone, the new mobile phone must first complete the discharge, then charge for 12 hours, then completely discharge, so we 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-ion battery. To perform multiple discharge charging processes, nickel-hydrogen batteries, such a battery has a strong memory, repeated charging and discharging process is also to make the nickel-hydrogen battery to achieve maximum charging upper limit.

Today's mobile phones use a lithium-ion battery, there is no need to repeat such complex battery memory processes. So, will the lithium-ion battery keep the highest power limit? The answer is inevitable is. Although the lithium-ion battery is called with a durable, the upper limit of the electricity limit is caused by the multi-battery cycle charge, which is formed by the monthly tired, and the original result is outside the normal charging.

Over charge is the culprit. How to understand how to fully charge is actually very good, that is, the mobile phone continues to charge the mobile phone battery in the event that the mobile phone is full. Continuous charging in the case of battery power, it can cause changes in the positive electrode material structure, resulting in capacity loss, and its analysis of oxygen and electrolyte will have severe chemical reactions, the worst result is naturally an explosion.

Cases of mobile phone explosion when actual life. For example, Xinhua Net reported that on March 4, 2015, a 23-year-old girl was charging and played with mobile phones. Shanxi Evening News also reported that the 18-year-old boy is playing mobile phone when charging mobile phones on June 15, 2015.

The original caused by these tragedy 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 it is a nickel-hydrogen battery or a lithium-ion battery. When excessive occurs, there is no doubt that the current transformation of the current is existed, resulting in a large amount of reaction of the lithium-ion battery positive electrolyte, consumes the maximum capacitance of the lithium-ion battery, when the heat is accumulated to a certain extent, fire, explode this Events are likely to occur.

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 mainstream mobile phones and chargers charged with USB ports.
