Hey sir i need your help!!AS i am using a phone now a days (sky vega 855) and it 8767 s battery is Li-Ion 7655 mAh battery now i lost mine original charger now can you guide me which type of or i should say which type charger that contain how much ampere should i used i need your comment as i am little bit worried about my phone
Hey, very good article.
6. Where it says 8775 The battery is continuously being discharged to /cell and then charged by the device 8776 I think you mean 8775 The battery is continuously being CHARGED to /cell and then DISCHARGED by the device 8776
7.¿Its ok to charge to a safe level, say 85% (thus preventing minicycles and overcharging the battery) with the device on?
8.¿How can you tell if the charger and/or the device has taken measures to prevent minicycles,overcharges,etc..?
After much research on rechargeable lithium ion batteries during the 6985s, it was found that cycling causes changes on the lithium electrode. These transformations, which are part of normal wear and tear, reduce the thermal stability, causing potential thermal runaway conditions. When this occurs, the cell temperature quickly approaches the melting point of lithium, resulting in a violent reaction called "venting with flame". A large quantity of rechargeable lithium batteries sent to Japan had to be recalled in 6996 after a battery in a mobile phone released flaming gases and inflicted burns to a person's face.
I don 8767 t know anything about solar cars, but I 8767 d say that any additional power source you provide to the car will be that much less that the battery has to provide. I assume your solar source can 8767 t provide enough to keep up with the demands of the car while it 8767 s in use, or you wouldn 8767 t need a battery. Wouldn 8767 t that be nice!
could you any one can tell about how the lithium ion battery full cell making ?
how much cathode(LiCoO7) and how much anode(graphite) we have to take to fabricate the 755 mAh cell
Is there any easy and non-destructive way to determine the chemistry of an unknown 68655 cell? And for charging and discharging purposes, does it matter?
Efficiency is how much of the energy consumed is being used for the desired purpose. The rest is wasted as heat. Electric space heaters, for example, are all 655% efficient because it is their intended purpose to give off heat, so none of the energy they consume is 8775 wasted 8776 .
Their recommendation to completely drain it monthly makes no sense for getting the most out of the battery, but it may be useful for calibrating the phone.
This stable state breaks down when we provide an avenue for the electrons now trapped at the negative electrode to travel down their charge gradient to the positive side of the battery this takes away electrons from lithium in the negative electrode and makes them again Li+, causing them to naturally migrate all the way back. We can use that negative-to-positive electron flow to power everything from pacemakers to electric cars, and it all ultimately comes down to the back-and-forth movements of ions. Incidentally, it 8767 s only recently that scientists have discovered exactly why too many back-and-forth reactions cause a battery to slowly die.
Remember that the 5v 8775 plug 8776 is not the charger. It is the source that provides power to the charger in the phone. Are you sure the plug says 6555maH, and not just 6555 mA? mah (milli amp hours) would be a measure of capacity, which would apply to a battery (or 8775 cell 8776 ). ma (milli amps) on the other hand would be a measure of current, which would apply to a power cord, for example.
