Piece of lithium battery on the first day only half of the electricity
Computer City's sales staff to answer questions on lithium battery life, often say "you can charge × 100 times." If you really understand, it was funny. In fact the correct way of expression should be "the life of lithium batteries, its charging cycle, the completion of the frequency of the number of charge cycles without any adulterous relationship
."
We all know that one of the advantages of lithium batteries is that you can at any time convenient time for the lithium-ion batteries, instead of insist want to run out after electrical charge. So, what is a charge cycles? A charge cycle means that the battery charge by the full use of all air, then air charge to the full process, this is not the same as one charge. Simply put, the 600 mA lithium battery, the first time you charge by the 0 mA to 400 mA APPLE M8403 battery ACER aspire 3000 battery , ah, ah used with N mA; then they charge you 150 mA, then the N mA ; Finally, full 100 mA, when the final charge to 50 mA when a piece of the battery charge cycle from there. (400 +150 +50 = 600)
Piece of lithium on the first day only half of the electricity, then it is fully charged. If the next day also so that half of the charge with a total of two charge down, this can only be counted as one charge cycle, not two. Therefore, usually it may take several times to complete a charge cycle. A charge for each complete cycle, will reduce power consumption a bit. This is why many people who use lithium batteries cell phones often said: "The broken cell phone, just bought 4 days back can now only use one charge 3 half days" reasons. However, this reduction in power consumption rate is very small, high quality battery charge cycle many times, still retained 80% of the original battery, after a lot of lithium-powered products in two or three years is still as usual. Of course, life lithium to eventually be replaced ACER travelmate 4600 battery Dell INSPIRON 6000 battery . ^
Lithium is generally the life of 300-500 charge cycles. Assumed to provide a complete discharge of electricity for the 1Q, if not to consider each charge cycle after the power reduction, while the life of lithium in its offer, or a total of 300Q-500Q for additional power. From this we know that if each with 1 / 2 on the charge, you can charge at 600-1000; if each with 1 / 3 of the charge, you can charge 900-1500 times. And so, if the random charging, the number of uncertainties. In short, no matter how full a total of 300Q-500Q added into the electricity that is constant. Therefore, we can interpret it this way: life lithium batteries and battery related to the total charge capacity, and the number of unrelated charge. Put deep and shallow depth charge put sufficient light for the life of lithium or less the same. So, some MP3 manufacturers publicity, said that "a certain type MP3 using powerful lithium batteries, rechargeable 1500 times or more." This is pure ignorance to deceive the consumer ACER aspire 5560 battery ACER BATBL50L6 battery .
In fact, light up light charge more for the benefits of lithium, only the product of the power supply module for the lithium to do calibration, the only deep deep release full of the need. Therefore, the use of lithium-powered products do not have to rigidly adhere to the process, all to facilitate the first, charging at any time, without worrying about affecting life

Chemistry question..elements?
When a piece of lithium is added to water it fizzes around on the surface of the water. a small piece of caesium explodes when added to water.
Explain in terms of electronic structure why a caesium atom is more reactive than a lithium atom
Caesium has a higher atomic number than lithium. Therefore, Caesium has a larger number of electrons.
As a result, Caesium has more electron shells than lithium.
The electrons on the outermost shell of lithium is closer to the nucleus of lithium than the electrons on the outermost shell of caesium is to the nucleus of caesium.
As a result, the electrostatic force of attraction between the valence electrons of caesium and the caesium nucleus is much weaker as compared to their lithium equivalents.
Therefore, the valence electrons of caesium are able "dislodge" themselves much easier as their lithium equivalents. And hence, the violent reaction.
