Advanced Technology and ... Low Tech Batteries?

It's ironic how every kind of technology is advancing except battery technology.

For example, can anyone make batteries that last a little longer to keep up with the high tech items they go into? What's the deal?

    Actually, battery "technology" has advanced a LOT, just not as fast as other things.


    I quote "technology" because 90% of the change has been the materials, and how they are suspended. THAT is why they are usually described by that! Alkaline(the electrolyte is alkaline, and not acid), lead acid(Uses primarily lead for the electrodes), NiMh, Lithium, etc... you get the picture. Almost all batteries are simply built of cells, and each cell is 2 materials that are somehow dissimilar with an electrolyte between them.

    That said, you're right! I just bought phones that had NiMh batteries! Someone PLEASE blow up those factories, and put it out of our misery!!!!! WHY didn't they provide Litium ion? I STILL remember some items where they came with NiMh, and you could buy Liion.

      hey guys ,you are right there is no such up to the mark improvement in the batteries technology .For example if we compare with the improvement and the technology of the cell phones with the batteries timing then there is a hell of difference. The batteries timings should be increased with the cell phone technology as well.

      :p:confused:

        What the heck do you mean, battery timings? It is a simple fact of physics that the higher the frequency, or the more circuitry, in a product, the higher the current drain is. It is ALSO a simple fact of physics that the less surface area, the less power available. And consumers often want things smaller and lighter, which means LESS power available, and they want things faster and easier, which means MORE power required. THAT is why larger systems can run longer, and why netbooks are so much simpler and slower. The larger systems take advantage to get more power. The netbooks try to reduce current draw.

        Is this REALLY improved technology? Not really. They simply found a way to fit more complicated circuitry on a smaller die. Thaat means faster, and easier to use, but the current draw isn't really reduced that much. onically, if they

        You know... If they could improve the ELECTRONIC technology, they could solve a BIG part of the battery problem! Maybe 10%+ of the battery power is wasted as HEAT! And that causes conductors to not work as well which costs MORE power/heat! And that could DESTROY the system in a few minutes or hours, so they have circuitry to shut the system down! And you DON'T want THAT, so they have FANS! And that requires MORE power! AND, since that is STILL not good enough, because there isn't enough surface area to cool things properly, you have HEAT SINKS! And that increases WEIGHT!

        BTW when I was a little kid, I don't think they made ANY battery under several pounds that could power the average laptop today. Lithium ion were literally a DREAM!

    Yes, the laptops are very powerfull but the autonomy is still 2-3 hours.
