Go Stanford Scientists

29 Nov

Potential damned good news from Palo Alto.  (I’ll try not to get toooo hopeful)

Storage is maybe the greatest problem when it comes to the practical use of alternative energy. Finding a way to hold on to that solar and wind power that’s generated only in specific time frames and conditions.

Looks like some guys at Stanford have solved at least a part of that problem.

Fingers are crossed.

Stanford Seeks to Boost Clean Energy With New, Super Long-Lasting Battery Electrode

Scientists at Stanford University in Palo Alto, California announced last week that they’ve developed the initial technology for a battery with a lifespan of nearly 100-times that of a conventional lithium ion battery.

Using a nanoparticle of copper, copper hexacyanoferrate, the scientists developed a battery electrode that survived 40,000 cycles of charging and discharging, compared to 400 cycles for a lithium-ion electrode. Even after 40,000 charges, the battery still managed to retain 80-percent of its original charge capacity, according to Stanford.

Not quite there yet though,………

However, as the researchers themselves pointed out, they are missing one key ingredient before they can even begin building their long-living battery: An anode.

Every galvanic battery contains an electrolyte and two electrodes: a cathode and an anode.

Although commonly represented by a positive and negative symbol, respectively, a battery’s two electrodes are actually technically distinguished by their relationship to the directional flow of the battery’s current. The current always flows from the cathode out of the battery and from outside, into the battery, through the anode.

The Stanford team created the electrode using copper hexacyanoferratte, but is still searching for the proper material for the anode, although they say they have several candidates in mind.
