In this iPad, iPhone rage era, twelve trendy electronic stuff is standard on every fashionista. But did you know that inside these gadgets can be hidden with a processor "time bomb", and obviously two to four years to calculate the preset time, the time it will start to self-destruct program, then you must always loved stuff can leave you. It really is the story behind it, so much as the ability? In fact, it is only one battery only.
Whether you know, buy electronic stuff from that day, it's a battery inside the body of the decline and fall tour on foot, gradually become longer limitless energy. This is the relentless passage of time to bring its wounds, Jiuzheng like that damn computer software, always unprovoked more slowly; Or like cell phones, but it will never be worth the care of unavoidable increases scratches. The aging process of cells who blame them? Of course, battery manufacturers can not escape stakeholders. But you know why? Let us work together to uncover the mystery of it!
How to charge the battery work?
We are talking about rechargeable batteries, generally refers to lithium or other similar batteries.
Simply put, the lithium battery works like this: an anode (negative) by the nature of the composition of non-metallic lithium compounds, and the cathode (positive electrode) made of carbon connected. When charging, the lithium-ion (or electrically charged atoms) in the external voltage is applied to the positive movement forced from the negative, and then save down at the cathode. When discharged, the lithium-ion storage and back to the negative current form, as this provides the energy or phone. (? Anode is the negative may seem contradictory to say that, in fact, Jiang Zi: the battery is inside the external negative anode, cathode is the positive internal external)
Charging and discharging are actually a chemical reaction inside the battery, the ions from the negative to the positive or from positive to negative in the campaign process, constitute a compound of positive and negative responses back and forth with the conversion.
While the other battery works are exactly the same. Lithium is a very good battery suitable for electronic stuff. It is light weight, simple structure, very suitable for rechargeable batteries. More importantly, after which several hundred times during the charge and discharge aging occurs, it is quite durable. But it will also have broken it, can not live forever.
Why does the battery will be aging?
Battery aging from which it was produced at the moment inevitably began, and this process is irreversible.
Assuming the battery capacity decreased by 1/3 or more even scrapped, then the lithium-ion battery, even if you do not buy, it will someday be scrapped. Under normal conditions, it is also only a few years of life; If you are a digital madman, it overloaded with work, then it's life may not be connected to two years. Because the battery is a chemical reaction process work, consumption is inevitable. After all, the presence of any chemical reaction can not ideal, will have loss of energy and some of the reactions to generate additional substances, batteries perform equally well.
This process refers to the negative battery in thousands of chemical changes in the process of gradual deterioration. Lithium compound constituting the negative electrode to absorb the continuous chemical reaction and releasing lithium ions, and its structure is undergoing changes, it becomes difficult to cause ion exchange. Make a popular analogy, it's like a kitchen rag, after washing many times, after wring become dilapidated, and finally completely lost as a rag function.
Greater threat of the battery, the internal metallic numerous chemical reactions resulting free material, this material will be a substantial accumulation of metal on the negative electrode, the positive electrode while a small portion will be gathered. Eventually leading to the formation of a metal coating on both poles, which for battery operation is extremely unfavorable.
