Battery revolution

Now the battery revolution has been in a high speed development. Take the safety into consideration, the battery of cellphone can not be too big or over 4000 mA. So the technology of energy saving itself is very important.

We always heard in some ads that the cellphone can be used for half a month or even longer. Or the battery can support the cellphone for a long time after charging. Is it true? Has anyone tried to use a cellphone more than a week? The answer we don’t know. But we can be sure the so-called longer using time is just in theory. Because we can not use a cellphone just let it in the normal situation. Every activity like make a call, send a message, visit the Internet will consume the energy.

So we not only should make the battery in a big capacity but also develop the charge technology.

If we can use the solar to charge a battery, we can solve the problem better. Now some companies have searched the area. I hope it can be mature one day.
