Redwood Materials will soon produce copper foil for battery anodes, made
from recyclate. Panasonic is the first customer.
Jigar Shah, head of energy services at Electrify America-
the charging company formed out of the Volkswagen diesel
settlement-said the company now has 150 " behind the meter "
li-ion battery backup installations at its charging sites in
the U.S., primarily to offset utility demand charges.
Unfortunately, Shah said recycled battery packs " don't currently
have the performance characteristics we need. " And
preparing used batteries for reuse involves more than simply
plugging them in, said UCS. " To be used as stationary storage,
used batteries must undergo several processes [including
testing, full discharge and reconfiguration] that are currently
costly and time-intensive, " the company's report said.
Another challenge is that a robust reuse industry will need
a reliable supply of end-of-life batteries. " Most of the batteries
are still in the cars, " said GM's Grewe. " Our first-generation
Volts typically have more than 100,000 miles on them
and are still going strong, " he said. " There's not currently a
high volume of batteries in the secondary stream. "
VW's Steven Rufo said that it's possible that second-life battery
reuse-proposed before recycling was a viable option-will never
get traction. " It may turn out to be better to put the material back
into cathode production, " he said. " But there's a lot of uncertainty,
and we're still very early in this process. "
The reuse and recycling of EV batteries is indeed still embryonic,
but it is gaining momentum, via research and considerable
investment.
