Well, so far we need to sell thousands of cars in order to have
thousands of spent batteries. And the demand will be huge for a long
time to come. Just one house consumes about 1MWh per month. If you
want just one day's worth of storage, you will need about 30kWh. That's
probably about 2 spent Leaf batteries. And that's just for one house.
Don't worry too much, yet.

Subject: Re: [EVDL] Ensure your spent li-ion batteries are properly
recycled/disposed-of
There will be a problem because we're talking about thousands of cars
being disposed of and I just don't see a market for that many used
battery packs. It's going to get to the point where the salvage places
will have to pay to have them taken away for recycling. Certainly there
are going to be opportunities for companies to "recycle" used packs
into something else like pre-packaged house or business systems but I
still think we're going to have a glut of used packs.
Things will get worse the first time a hastily put together backup
power back burns a house down and everyone attempting to re-use them
realizes they need to implement proper battery management. Plus as
battery chemistry and technology changes the older ones will become
even less valuable.
We may not see a problem for five or ten years but I predict we will
see a problem.

First, the car owner will be done with the battery well before its
useful life is over. So he'll swap it or junk the car with the
battery
in it.
Next, whoever receives the partially spent battery will have a strong
incentive to resell it for backup power, or whatever. So he's not
going
to send it to a landfill. Also, too heavy: the dump charge would be
significant.
Third, whoever buys the spent battery for backup power will eventually
have the ultimate disposal problem. If these are home owners, then
there could be a problem. However, again, the dump charge would be
high
so finding a place to take them for recycling is a good incentive.
