How to ensure that the mobile phone lithium battery is easy to use, is you right?

Many people find that after using some days, the mobile phone battery is getting faster and faster, the standby time is getting shorter and shorter. In order to make your own mobile phone battery more durable, many people choose to help the network, do the methods of "how to extend battery life". But do you understand? Many charging methods on the Internet are wrong, so many years have been being puddled.

When the power is completely exhausted, charging it? No! "Depth discharge" will damage the battery before, the battery has a memory function, and the mobile phone battery is fully exhausted and charge the mobile phone to 100%, otherwise the battery will " Remember "the proportion of charge, make the power have not used much to charge, and charging will not be filled. "Now that smartphones are used by lithium-ion batteries, lithium ion battery technology and structures have undergone tremendous changes, and the battery's battery is completely exhausted. "New Energy Power Lithium Battery Lead Company, Tianneng Lithium Electric Call R & D Engineer Wang Yong just told the technology daily reporter, the battery is completely exhausted so-called" depth discharge ", which may affect the internal material structure of the battery, shorten battery life.

When charging, Zheng lithium ions are "jumped into" electrolytic solution, "swim" renders in the electrolytic solution, "swimming" to the negative pole, combined with electronically running from the positive and running; on the contrary. Dr. Zhang Hua, who graduated from the University of California, Los Angeles, and the department of Zhang Hua, made a bit: Whether it is discharged or charging, lithium ions have to take out from the original structure, a bit like a pile of things from a room to another.

Room. Therefore, the understanding of battery life is based on the basis for the understanding of the battery structure. That is, during the charge and discharge process, the less the lithium ions involved in the motion, the smaller the damage to the structure; the slower the lithium ion involved in the movement, the smaller the destruction of the structure.

If the lithium ion runs almost, it is necessary to "depth discharge", continue to extract lithium ions from the inside, and there will be damage to the battery. When the power is full, it is necessary to end the charging immediately? Don't! The battery has "overcharge protection" network transmission when charging the mobile phone, and the power is charged to 100%. It will immediately end the charging, otherwise it will damage the battery life.

In this regard, Wang Yunang said that it is not too worried. Lithium-ion batteries are generally provided with "overchair protection". When the battery is fetched, it will automatically convert into a flow charging, that is, the charging is very slow and the current is very small.

When the electricity is filled, it will automatically power out of the power. Will not continue to charge over, so it does not have too much impact at a time to 100%. Many people like to sleep for a night before going to bed.

In this regard, Wang Yongang said that there will be power loss at night, and how much power is consumed, the charger will continue to be filled with the phone. "But so long cycle, there is a certain impact on battery life.".

"Spoose charging will damage the battery?" Shallow charge-free "Battery is beneficial to the battery" The life of the lithium-ion battery can reach hundreds of charge and discharge cycles. The charge and discharge cycle here refers to the process of re-filled the battery after light. Instead, it refers to the battery inserting the charger and then unplug it.

"Wang Yongang said that" shallow-screen charging "is performed on the lithium ion battery, that is, the sporadic time is charged, so that the structure of the positive and negative electrode material is small, but it does not affect life. "So, we usually emphasize that the charging and discharge of the lithium-ion battery should be shallow and shallow, do not challenge the battery 'limit'. Zhang Hua said.

While charging, playing games, playing games, watching videos, etc.

are high current consumption, the current supplied by the charger is smaller than the mobile phone consumption, while charging the phone to output current from the battery. That is, at this time, the battery is not charging, but is discharged, and even the battery capacity is quickly "exhausted". Lithium-ion battery life is closely related to the number of charge and discharge cycles, while charging, the battery is quickly charged, the discharge is constantly switched, which will affect the battery life.

Putting the phone in a high and low temperature environment due to the instability of the electrode in the electrolyte, each time it charges and discharges, the two electrodes of the battery will chemically react, and the active substance is consumed, and the chemical energy reduction of electrical energy is reduced. Battery capacity drops. The ambient temperature is too high, which will accelerate the chemical reaction of the battery and "self-discharge", reduce battery capacity; low temperatures below zero will also have a negative impact on battery structure, even permanent damage.
