Not much to see but a couple friends at Raytheon turned me onto some sites. I included the link to one as it does not require any password or clearance.
Some cool stuff coming down the pipe in about 3 years or sooner. Lithium, unfortunatley is still the top dog and "they" are still concentrating on this but doubling (or more) the storage capacity in the same size cells. The zinc air batts are a wash from what i was reading, not enough amps and problems with internal shorting, and the lithium air batts are a roller coaster ride of work and not work (same problem). A couple startups and a company testing with NavSea have also doubled the capacity (lithium again) and dishcharge but this stuff is years away from our boats unlike the above tech.
On the bright side, those crazy kids at MIT, the ones that gave you guys the A123 brand now have another potential spinoff they just patented in march of this year, a slurry battery that has some insane storage capacity, though from reading it i do not see the small battery applications because of the "liquid sludge" it uses, that and it needs to be circulated. But i could be wrong. A quote:
"SolidEnergy introduced a patented battery technology that has more than twice the energy density of a regular lithium-ion battery, and can safely operate from -40C to 250C (Temp). It is also the first rechargeable battery with the potential to be used in oil drilling, enabling recharging downhole. The battery technology also has potential applications for consumer electronics, electric vehicles, biomedical devices, and the military."
