Replacing Lithium with Sodium in Batteries

Replacing lithium with sodium in batteries:

An international team of scientists from NUST MISIS, Russian Academy of Science and the Helmholtz-Zentrum Dresden-Rossendorf has found that instead of lithium (Li), sodium (Na) "stacked" in a special way can be used for battery production.

[...] They found that if the atoms inside the sample are "stacked" in a certain way, then alkali metals other than lithium also demonstrate high energy intensity. The most promising replacement for lithium is sodium (Na), since a two-layer arrangement of sodium atoms in bigraphen sandwich demonstrates anode capacity comparable to the capacity of a conventional graphite anode in Li-ion batteries—about 335 mA*h/g against 372 mA*h/g for lithium. However, sodium is much more common than lithium, and therefore cheaper and more easily obtained.

    and you thought lithium battery fires were bad..

    Bad? Depends on your point of view. If I'm in it, yeah. If I just get to watch it...

    Heh, I am reminded of this scene in Invader Zim: https://www.youtube.com/watch?v=uDIgS-Soo9Q [youtube.com]

    Zim: "I put the fires out."
    Tallest: "You made them worse."
    Zim: "Worse, or better?"
