Davy obtained a small amount of lithium by electrolysis of lithium chloride. In 1855 Bunsen and Matthiesen studied the properties of lithium by electrolyzing lithium chloride to obtain enough lithium.]]> 2018-10-18 12:34:48 UTC https://padlet.com/michael_cheng1/rikxsccsbyw9/wish/294299447 michael_cheng1 https://padlet.com/michael_cheng1/rikxsccsbyw9/wish/295784794 Lithium batteries find application in many long-life, critical devices, such as pacemakers and other implantable electronic medical devices. These devices use specialized lithium-iodide batteries designed to last 15 or more years.

Lithium batteries can be used in place of ordinary alkaline cells in many devices, such as clocks and cameras. Although they are more costly, lithium cells will provide much longer life, thereby minimizing battery replacement. 

Lithium batteries also prove valuable in oceanographic applications. While lithium battery packs are considerably more expensive than standard oceanographic packs, they hold up to three times the capacity of alkaline packs.

Brine excavation is probably the only lithium extraction technology widely used today, as actual mining of lithium ores is much more expensive and has been priced out of the market.
Lithium is present in seawater, but commercially viable methods of extraction have yet to be developed.
Another potential source of lithium is the leachates of geothermal wells, which are carried to the surface.Recovery of lithium has been demonstrated in the field; the lithium is separated by simple filtration.The process and environmental costs are primarily those of the already-operating well; net environmental impacts may thus be positive]]> 2018-10-23 05:12:04 UTC https://padlet.com/michael_cheng1/rikxsccsbyw9/wish/295785693 michael_cheng1 https://padlet.com/michael_cheng1/rikxsccsbyw9/wish/295882017 Image: lithium metal lithium (Li) stored in paraffin33Image:
