New technology batteries?

[force9BOAT]

Hello,

I've been away from this discussion board for about a year but am back now.  I'm wondering, has there been any move in solar/wind RE away from lead-acid batteries towards new technology such as batteries used in hybrid cars?  Lead-acid seems like outdated technology.  I'm wondering if volume production of large new technology batteries is driving their prices down.

Thank you,

Rob

hi, these look promising.

http://www.deeyaenergy.com/

about one year away if there website is to be believed.

anyone know anything about them or are close enough to go and have a look.?

 Deeya has an "investor" tab on the left there. Never a good sign IMO.

 I think lead acid is still the most common round here, and probably will be for some time to come.

IMHO: there are a number of technologies coming down the pike, but most aren't as robust and the good ole car battery types.

I use NiCds cause I get 'em free :-) and they take abuse better than lead-acid types.but they are much more chemically dangerous that the L-A types, plus with the L-A type can be recycled almost totaly to make new ones. The posts and plates can go and be smelted down to make new posts and plates. The acid can also be either re-used or cleaned up and neturalized.

Once the Li-poly batteries become much more available and heat/cold stable then I'm thinking they will begin replacing the L-A types. I hope so, since they weigh about 1/2 the L-As and can come in different shapes and sizes to meet the demand.

Welcome Back :-)
