Can your refrigerator bring your lithium battery back to life?

Recently there is a rumor that put the useless lithium battery in the refrigerator frozen for three days, then it will come back to life, and can use normally. Really?

In this paper, starting from the next leg of said battery refers to the notebook computer use lithium battery, may also have some truth to mobile phone use lithium battery (I'm not sure), but not ordinary camera commonly used Ni-Mh battery or anything else., in fact, there is evidence that the depth of the charge and discharge method of Ni-Mh battery is really effective, and frozen equivalent to a disguised depth charge and discharge the battery, so also should be effective, few people would, of course, in order to save a few section of the dry cell to risk of batteries may burst huge money).But the aging of lithium-ion batteries are generally caused by batteries materials disintegration, is irreversible.

Shells net time is too short, not enough I myself for to a piece of scrap batteries to do the experiment. And because I have more than fifty percent sure doubt that doing so would cause permanent damage to the battery, so I was reluctant to take the battery to try, just have to go to collect the information on the network.

First of all, I noticed that this thing is said to be in Beijing television station of "the big survey columns tested, the result is: no use! Find an expert, but now experts television show me then say casually useless, it really doesn't work? Why there are so many people in the online?

I want to look for those who still say useful person. Skip those copied to re-post and there is no evidence of good, I can find the most domestic Internet early experiments word for "2005 a paper entitled" zombie resurrection of notebook lithium battery rebirth write "post.(see http://www.pxue.com/Html/311.html, yes, I know this is not the original post, post clear written from a dedicated network (51 nb.com) turned, but I don't know is what reason, especially the original post on the net has already gone.@ small garden students listen to the wind, your starting point and I'm the same view!

Worthy of our attention is that in this paper, the author made clear that it was his from the Hong Kong found a mobile phone on the BBS of recovery method of mobile phone batteries. He took on the laptop batteries to try. And after the preliminary search, I also not found prior to the date of this article about computer lithium battery freezing method, so I strongly suspect this is the starting point of all frozen legend notebook lithium batteries.

Another is the most important details is not in the body, and in the body in the comments below. Exempt responsible turn this period of important comments also copy to come over: freezing treatment after a total of seven times the power supply experiment was carried out on the battery, five times before the batteries are more than an hour, and significantly higher level before freezing, starting from the sixth power supply complete recovery to the front of the frozen state. So the recovery of frozen only for a short time.

Careful search will find on the Internet, there are a lot of announced failure the posts (including many to refrigeration instead of frozen amateur).While those announced the experiment is successful and provides experimental data post there is a common phenomenon, it is only in a very short period of time after the frozen, and then not again. Is not only a laptop lithium batteries, cell phone lithium battery is the same. For example, in 2007 another paper entitled "the phone old batteries can use the refrigerator repair?" The articles of the urban express from Hangzhou, see http://news.sohu.com/2007020 (I am a go here to want me to harmonious?)9 / n2481359 (because I maxed out proposition among?)78. SHTML, pay attention to not, frozen battery filling paste pictures are from this article. This article by netizens copied the one thousand six hundred times, harm I draw with great effort to find the original, don't know when reprint the mark of the author is at the very least ethical?)

A laptop in the lithium battery in addition to the batteries and other components, which is some control circuit and chip, is used to judge the battery charging status, such as protection of the battery, it won't let you overcharge burst, and won't let you complete the battery light. This is because the thoroughly all the light electricity will produce permanent damage to the battery slot. Protection circuit is under low power to the red line before cut off all the contact and the outside world. Bought new lithium-ion batteries, head a few times when using need depth charge and discharge, is to protect the system to the calibration parameters.(of course, later don't depth charge and discharge frequently, that is the tube.)

Said a long time in front of the freezing depth discharge process is actually a mandatory, but also to let those protection circuit has failure. I strongly suspect, frozen is disrupting these parameters, allow the battery to in the case of safety violations savings last power work several times, at the cost of battery internal permanent damage. Of course, your battery is already dying, don't care about bear more pain.

I just posted online speculation yesterday, has been to my guess. Well, in principle I don't really know, it is entirely possible that is wrong. I go on the Internet also searched the principle of search results more confused, in my many years-experience of learning science and reading science fiction, the explanation sounds more like science fiction than science, I wouldn't have paraphrased.

But the principle is unknown conclusion does not hinder us to collect data. I know a lot of impatient readers have to skip the habit of long passages directly see the conclusion. So what is the result of this article, the freezing method is really effective? For the effect of freezing I associate it in two words: dead-cat bounce.

All in all, there is no practical value. You can buy a new battery for a few thousand dollars, or make it be frozen for three days and then take out for another five times usage. You don't need to be so stingy. I need to emphasize again that here is the resurrection notebook (may also include mobile phone) of the scrap lithium battery. We are talking about the resurrection but not a collection, nor other varieties of the battery. If it is nickel metal hydride battery or nickel cadmium battery, because they have different principles, in some cases the method would work. What I said is not the button battery on you watch. The data is insufficient, so we can't analyze clearly.
