New Sodium ion Battery making the rounds.
« on: December 01, 2015, 06:01:39 PM »
And no actual data available. 

A team of researchers in France has taken a major step towards powering our devices with rechargeable batteries based on an element that is far more abundant and cheaper than lithium. For the first time ever, a battery has been developed using sodium ions in the industry standard "18650" format used in laptop batteries, LED flashlights and the Tesla Model S, among other products.

"The sodium-ion battery unveiled today is directly inspired by lithium-ion technology," explains solid-state chemist Jean-Marie Tarascon from France's Centre National de la Recherche Scientifique.

In other words, like the lithium ions in lithium-ion batteries, sodium ions travel from one electrode to another through liquid during charging and use cycles without modifying the materials in the battery. The researchers are keeping those specific materials a trade secret for now, but the performance of the prototype battery is promising.

"Its energy density is comparable to certain lithium-ion batteries, such as the lithium-ion iron/phosphate battery," points out Loïc Simonin, a collaborating researcher at LITEN (Le Laboratoire d'Innovation pour les Technologies des Energies Nouvelles).

Saltbattery now in this shop. Cut off a piece of copper tubing, wrap a piece of cotton around this and bend lastly an aluminium plate around the tube. Dip this once a week in (kitchen) saltwater. The yellow LED will light for at least a week ;) See photo:

Nice. I am hoping the inventors are doing something more then just exploiting the galvanic potential difference of metals in an electrolyte (salt water).  I would laugh if you open it up and see 3 copper and 3 aluminum plates with saltwater soaked separators delivering 1.5V but only 20mAh . Hold on I was wrong the power rating is on the side of the battery it's "HIGH POWER"  should be fine then :-)
