Lithium is an element how can it be deleted?
If Lithium is chemically changed what prevents it being chemically changed back?
Batteries are sealed, if material does not leave than all the components used to make it are still inside the battery.
- jeffbee 5y ago> If Lithium is chemically changed what prevents it being chemically changed back? Thermodynamics. It is also tremendously difficult to get your gasoline back after you burned it, or to un-cook an egg. It is not difficult to recover lithium from a battery, but in general do not assume that physical processes are easily reversed.
- alisonkisk 5y agoThe energy you get from burning gasoline is about as much as the energy cost of creating it. It's not a complex organism like an egg. https://www.scientificamerican.com/article/turning-carbon-dioxide-back-into-fuel/ https://www.scientificamerican.com/article/turning-carbon-di... The only reason it's not done is because already made gasoline is cheaper.
- jeffbee 5y agoThat whole article is about how even with zero-cost energy it would still be double the expense of fossil fuels. Nobody doubts that you can make liquid fuels from solar energy and atmospheric CO2 … that is a plant’s life. The problem is it’s hilariously inefficient.
- GordonS 5y agoIt's not something I ever gave conscious thought before now, but yes, the depletion assumption sounds a bit silly in retrospect. If the lithium has changed chemically, presumably the feasibility of changing it back depends on the nature of the change.
