Battery/Heater?...NAS battery

NAS battery
NAS battery principle
A type of battery that uses sodium (Na) at the negative electrode (cathode), sulfur at the positive electrode (anode), and beta alumina as a solid electrolyte. During the discharge phase, molten metallic sodium at the core acts as the anode, separated by a beta alumina cylinder from a sulfur container made from an inert metal acting as the cathode. The sulfur is absorbed in a carbon sponge. Alumina is a good conductor of Na ions but a bad conductor of electrons, avoiding self discharge. When Na gives off an electron, the Na+ ion migrates to the sulfur container. The

electron travels through the molten Na to the contact and through the electric load to the sulfur container. Here, the electron reacts with S to form S-, which then forms sodium polysulfide. As the cell discharges the sodium level drops. During the charging phase the reverse process takes place.

The cell is usually made in a tall cylindrical configuration. The entire cell is enclosed by an inert metal container and sealed at the top with an airtight alumina lid. The cell becomes more economical with increasing size. In commercial applications the cells are arranged in blocks for better conservation of heat. Once running, the heat produced by charging and discharging cycles is enough to maintain operating temperatures and no external source is required.

An NAS battery has a high energy density and high efficiency of charge/discharge, and is made from inexpensive, non-toxic materials. However, the operating temperature of 300-350 °C and the highly corrosive nature of sodium make it suitable only for large-scale non-mobile applications. One such application is the storage of energy storage, during off-peak times, in the electric grid.

( the temp this thing produces surly can be used for,... you name it? ).

want pics? ok.

Very excellent information,  Thank you.    Are there any specs on this you know of concerning output and lifespan?

[b0rg13]

if you google this and read over a few pages of this battery youll find its VERY HIGH out put and around a 15 year lifespan.



....but what i had in my mind was a device like this but about the size of say a micro wave to run a house for eg,.. or portable power.,....place one under your bonnet and trunk to run a car?..

...electricity and heat...

...btw these batterys are real and out there NOW and WORKING.

Very simular to my earth battery
but ground was the conductor is the
power ac or dc I couldnt figure out how to use this
