New Battery Technology

[rgleason]

This thread is devoted to highlighting and discussing new battery technology and types that are promising and preferably in production.

One likely possibility is http://aquionenergy.com/
Stainless Steel, Cotton, Manganese Oxide Electrode, Carbon Titainium Cathode, and Saltwater. Very safe, long life, good partial state, sustainable, good temp tolerance, low power density and delivery, inexpensive. Good for solar, not for fast charging.

"Aquion’s batteries use sodium ions from saltwater as their electrolyte. Electrical current moves through this brackish liquid from positive electrodes based on manganese oxide to negative ones based on carbon. The batteries are large and operate slowly, but they are also manufactured cheaply, using repurposed manufacturing equipment. Last week Aquion announced $34.6 million in funding to help it scale up production."

"The batteries cost about as much as lead-acid ones, which are sometimes used now, but they last twice as long, effectively cutting the long-term costs in half (see “Demo: Storing the Sun”). Other long-lived batteries exist, but they cost far more than lead-acid batteries.
The new energy storage technology could be crucial to making renewable energy more viable, especially in remote locations. "
