Engineering360: "Researchers repurpose EV batteries for energy storage in developing countries"

It would be interesting to see how these get disposed of in developing countries once the 80% becomes <10%.

Once again we ship off our unwanted waste to third world countries and leave them to deal with our disused "green" products. Does this mean that the "green" EV batteries are only capable of using 20% of the battery life?

"Virtually all automakers working on electric vehicles are also working on recycling the batteries since they are going to still be extremely valuable after being depleted. And lithium ion batteries do not have a hazardous waste designation in the US – however, the lead acid batteries in every diesel vehicle do...

"One of the biggest mistakes they are making is that they are comparing the full production and lifecycle of an electric vehicle, including the emission from the electricity uses, against the production and lifecycle of a diesel car without accounting for all the energy used to produce the diesel and supply it to the cars."

" Based on where EVs are sold in the U.S. in 2015, the average EV produces global warming emissions equal to a gasoline vehicle with a 68 mpg_‑US (3.5 L/100 km) fuel economy rating."

Also, most battery applications lose their effective use after they go below 80% charge capacity. E.g. a 14V battery in a ICE vehicle delivers 11.2V at 80%-- can't start the car, battery is dead.
