The Circle of Battery-Life
The more hybrid cars and battery electric cars are on the road, the more
battery pack we'll eventually have to deal with. It's still a better problem
to have than to have to deal with vehicles that burn significantly more
non-renewable fossil fuels, with the waste products going straight in the
atmosphere. At least the batteries are recycled, and consumers are being
paid for their old batteries (which usually can still hold a lot of charge,
so some might be

recycling). But so far recycled batteries weren't always turned into new
battery. That might change in the future...

Toyota Motor Corporation, along with Toyota Chemical Engineering, Sumitomo
Metal Mining, and Primearth EV Energy, have partnered to recycle nickel in
used hybrid-vehicle nickel-metal-hydride batteries for use in new
nickel-metal-hydride batteries. The new facilities are only in Japan for
now.

"Previously, nickel-metal-hydride batteries recovered by car dealers and
vehicle dismantling businesses were subjected to reduction treatment, and
scrap containing nickel was recycled as a raw material for stainless-steel
manufacturing. Now, with the development of high-precision nickel sorting
and extraction technology, materials can be introduced directly into the
nickel-refining process, thus achieving 'battery-to-battery' recycling." (

I'm hoping that the same will be done with lithium-ion batteries, which will
no doubt be more popular than NiMH batteries in the near-future. Li-ion
batteries are

xic-recycled.php> already being recycled, but it would be great if they were
turned directly into new batteries using processes that are as green and
energy-efficient as possible.

I also encourage Toyota to bring this process to other markets where they
sell lots of hybrids (North-America, Europe) as soon as possible.
