    Scientists Find Cheap And Easy Way To Extract Lithium From Seawater |

    Researchers at King Abdullah University of Science and Technology developed what they believe is an economically viable system to extract high-purity lithium from seawater.


    According to the researchers, the cell will probably need $5 of electricity to extract 1 kilogram of lithium from seawater. This means that the value of hydrogen and chlorine produced by the cell would end up offsetting the cost of power, and residual seawater could also be used in desalination plants to provide fresh water.

    LiIon Batteries are going to get really cheap in about two years….

    Consider the rare earth elements needed to catalyze the reactions. 5 bux per kilo is reflective of only part of the costs. All the same, I'm enthusiastic about the prospects. (Note that the King Abdullah Univ has a large proportion of expat Chinese on staff.)

    With other battery tech in the rise, and some looking to be vastly better then Lithium in any form, I expect to see a near quantum shift toward sustainable electric power for almost everything! Graphite seems to hold much promise, as it's much more neutral both in construction, charging, and recycling, cutting one of the biggest expenses from the cycle!
    Gonna be interesting to watch it unfold!

    I'm already experimenting with Graphine batteries, and have found the power density to be vastly greater then any other battery currently available, so much so that I'm switching my aircraft over to these batteries, and major bonus is they are completely safe, no fire or explosions, and no parisitic drain across cells, nor a need to balance charge them to ensure equal cell charge rates!

    ^^^^ I find this very interesting. I will have to do some reading, thanks! Would sure be nice to use something besides lithium in my dive lights.

    Hydrogen isn't that valuable.
    Using $5 of electricity is only about 50kwh.
    If I remember correctly if the electrolysis was 100% efficient you would get 1kg of hydrogen per 40kwh of electricity.

    Yeah but if US Mag or Dead Sea Mag uses that process to get the lithium from their processes that will be tons of extra $ with little added cost. Great salt lake and the dead sea both have decent lithium content. Dealing with elemental lithium is a serious pain in the butt.

    I remember when cold fusion was announced by researchers and it was herald as the next cheap power source. However it never panned out and the researchers were discredited. This lithium extract I will hold off judgment until it is proven

    The battery makers are looking for lithium phosphate.

    Phosphorous can be extracted from Seawater as well…

    I was thinking of that when I read about this, so much hope and promise and one hell of a let down!

    You could tell cold fusion was fake due to the lack of high energy neutrons.
    I could smell bullshit when people were standing around unshielded reactor and not dieing.

    What about Salt Reactors???? I heard a bunch about that some years ago, seems like Salt Water could generate electricity under the right conditions! Or was that another bunch of Bullsnot?

    Molten salt has been proposed for reactor cooling (i.e., heat transfer from the reactor to another heat exchanger of some kind. So far as I know, the studies ended at the pilot plant level if not sooner. Heard nothing on it for years.

    Oh they are real. They use a consumable anode made out of aluminum. Obviously it takes more energy to make the aluminum than you get out of the battery.
