The battery cells are not that big issue in the Tesla packs. Tesla will not pay more than $100/kWh for their cells in the near future.
Just to give some idea: One bought 20.000 kg of LiFePO4 cells in 2004 (~$300/kWh). They contain 23% of pretty pure copper. That's 4,6 tons of it. It cost in 2004 about $2000/ ton (of course the battery grade foils cost more but just to give a sneak peek to the industry). If the cells are considered to be at recycling threshold today it is not necessary to buy 4,6 tons of copper with $7000/ ton to get new cells. Offer to replace the old pack at reasonable cost and get many of the raw materials for "free". Old pack mechanics are probably in usable condition so it might be possible to recycle it as-is. As additional business model Tesla could make customers pay per used kWh from the pack. Never mind what the battery actually costs. If it's easy to swap and the packs are always in +200-mile-condition. Who cares. This is all about scaling it up. What this does to the usability of the EV donor and how well it keeps it's value? Car may become actually an investment not a money pit. -akkuJukka http://www.google.com/profiles/jarviju#about 2013/6/22 Marcus Reddish <[email protected]> > hmm, I must have missed that part of the plan.
