What happens to batteries that leak and no longer work?
- darkmarmot 10y agoRecycling batteries, especially large ones, is very cost effective.
- toomuchtodo 10y agoWhat darkmont and mikeyouse said (Tesla warranties their batteries for 10 years). And fires? https://electrek.co/2016/12/19/tesla-fire-powerpack-test-safety/ https://electrek.co/2016/12/19/tesla-fire-powerpack-test-saf...
- hueving 10y ago10 years? That's pathetic considering the cost. Tesla's powerwalls still aren't even close to economical.[1] "Even at Tesla’s low wholesale price, a 500-cycle battery just doesn’t pencil out against the alternatives, especially once the inverter and other system costs are included.

The newer version was unveiled recently, and here's some info on PW 2: https://electrek.co/2016/10/28/tesla-powerwall-2-game-changer-in-home-energy-storage-14-kwh-inverter-5500/ https://electrek.co/2016/10/28/tesla-powerwall-2-game-change...
- mikeyouse 10y agoYou can recycle almost all of the Lithium and other metals in modern batteries.
- omginternets 10y agoHow much energy does that require?
- mikeyouse 10y agoMuch less than digging it out of the ground. https://www.researchgate.net/publication/265158823_Paper_No_11-3891_Life-Cycle_Analysis_for_Lithium-Ion_Battery_Production_and_Recycling https://www.researchgate.net/publication/265158823_Paper_No_... > Further, the recycling of Li-ion battery materials potentially reduces the material production energy by as much as 50%. If battery active materials can be recycled in forms suitable for reuse with minimal processing, this percentage reduction could be even higher, as considerable energy is committed to making them from raw materials.
- spangry 10y agoIf cost-effectiveness is a factor, unless Tesla manage to reap some pretty massive economies of scale, realistically we should be talking about recycling lead-acid batteries (like the one in your car). They are, by a pretty large margin, the cheapest method of storing energy: https://en.wikipedia.org/wiki/Comparison_of_battery_types#Common_characteristics https://en.wikipedia.org/wiki/Comparison_of_battery_types#Co...
- rwallace 10y agoIf the proposed solution is to scatter a zillion tons of lead around the place, I suggest we go back to burning coal instead. It would be less environmentally damaging.
