> But Goodenough is equally dismissive of such tinkering and its measly 7% or 8% a year in added efficiency. 7% extra efficiency per year means electric cars will have twice the capacity in 10 years...and then double up again in 10 more years...and so on. That's a far greater rate of improvement than for gasoline-powered cars, even if we're impatient and we want our $10,000 500 mile on a charge EVs now . > But the pa…
What I'm worried about is the waste of lithium and other battery/accumulator metals. In theory, people should turn electronic devices and batteries to recycling facilities, but a large part of the population ignores the rules and throws their gadgets into the trash when broken... I wonder if someday we will find a way to "separate" trash on atomar level (i.e. put arbitrary stuff in on one side, get raw atoms on the o…
At the moment recycling technology can already grind stuff into small particles and float it in salts of different densities to separate it. That doesn't go to atomic level of course...
I think it's a fundamental outcome of the laws of entropy that separating always takes a lot more energy than mixing, so if you've mixed it, you've lost the game already.

An example of the dangers of extrapolating.
CPU speeds kept going up - until they didn't.
Battery tech is not going to keep going up 7% each year. Although perhaps his 60% improvement will show exactly at the right time to effectively be 7% better than the previous year.

Well that would require a lot of energy !
One probably can't get a resersible process, but just adding up the energy to break all the trash can be wrong by several orders of magnitude.

Yes we would. All these things existed without Li-ion. The power/space budget would be more constrained but it was perfectly achievable. What wouldn't work is senselessly burning cycles running managed code in a VM with heaps of battery sucking DRAM. People today have no concept of how much computing power is wasted as excess heat because of modern software development practices.

Todays landfills are tomorrows mines.
