Default Maybe soon a new Sodium electrode to replace lithium in the batteries.

Interesting news, especially because the sodium is very abundant and cheaper than lithium.

To say that with the growing demand for lithium in recent years, the cost has
gone from $350 a tonne in 2003 to about $6000 a tonne in 2010 (approx).

New electrode material could lead to powerful rechargeable sodium batteries

Default Re: Maybe soon a new Sodium electrode to replace lithium in the batteries.

It doesn't seem very useful to us as the cell voltage is lower than li-ion ones...

About the same as LiFePo4 batteries actually. Might be safer?...

Also the charging cycle's a debte.. their experimentation says it was holding less charge over 30-charging cycles. That does mean that the chemical compositions is still not good enough..

Haha, Yes, but may be that we still have time to buy a few acres of land with brine in Chile, Argentina or
in the Salar de Uyuni in Bolivia, where it is estimated that the largest reserves of continental lithium

But the sodium may be spoil the party to us
