    Next-generation lithium cells will double phone's battery


    The lithium ion batteries in your mobile devices are inherently limited by the "ion" part of their name; they can safely use lithium only in the part of the cell that supplies ions, wasting a lot of potential energy. It's good news, then, that researchers at Stanford have developed a new lithium battery that could last for much, much longer. The technique allows for denser, more efficient lithium in the battery's anode (which discharges electrons) by using a nanoscopic carbon shield that keeps the unstable chemical in check -- uncontrolled, it can quickly shorten the device's lifespan.

    Efficient electrical storage has been the holy grail for quite some time now. Nice to see advances of any kind. Solar and wind technology could actually replace oil someday if they keep it up.

    Batteries have come a long way but for phones, every time they get battery better they make it thinner so duration stays same or even worse.

    This is quite a breakthrough if true to be two to three times the battery life. The whole idea of RT was for it to run on less energy-consuming processors. Perhaps now they can design all devices to run Intel processors or similar so as to run full Window OSs.

    Here's another device I read about five or so years ago and wondered what ever happened to it.

    Supercapacitors and Ultracapacitors

    New Energy Storage


    Super capacitors merged with batteries (hybrid battery) will become the new super battery. Just about everything that is now powered by batteries will be improved by this much better energy supply. They can be made in most any size, from postage stamp to hybrid car battery pack. Their light weight and low cost make them attractive for most portable electronics and phones, as well as aircraft and automobiles.

    Hope so, so many things on hand held devices and no power for them. My Galaxy lasts only couple of hours if WiFi and GPS are on, just long enough to get lost relaying on it.

    Hopeful too. I'm quite surprised with the battery life with this Nokia Lumia 1520 running WP8.1 DP for what it does. I use it quite heavily all day with 25% left each evening on average. Charging time is quick also.

    Read about them awhile back also. The dis-advantages listed are probably holding them back. I worked with both low and high voltage caps in the Air Force and they can certainly pack a punch. They do discharge themselves quite quickly though. If they were incorporated into a wind/solar system where they could be recharged frequently, they may have promise. On a smaller scale with phones and such possibly a small solar cell or electro-mechanical charger inside the device could keep the capacitor charged.

    I heard they use nano carbon particles for capacitors to slow down discharge. Tesla cars is working on that right now. New battery factory just for that.

    Didn't know Tesla was using them......cool!

    Hi there.

    Samsung S5 (with latest update from Android) seems to do pretty well -- I can usually get through an entire day with still around 15 - 20% remaining -- before the update I would have needed a "Lunch Time" recharge / top up. Maybe some of these phones should have a trickle solar charger -- even if it can't charge the whole phone completely it would perhaps give people 1 or 2 hrs more before they have to connect to a mains supply.

    Whatever the efficiency of the battery you can't break the laws of physics -- if your phone uses so many WATTS then you will need the same nr of watts to re-charge it --Ohms law P (Watts) = I (amperes) * V (Volts). Your battery needs to supply so many mA /hr to be able to supply the phones need whatever technology you use.

    For our more "Technologically challenged colleagues " :
