Re: How many battery "breakthroughs" is that this year?
Because it is simply not possible.
"cheap, safe, long-lasting batteries" and "much more range in their electric vehicles" are two mutually exclusive things as range requires nothing else but higher energy density. Or lower power consumption. Or more batteries.
If you try even triple energy density of Li-Ion battery (0.875MJ/kg x 3) you're right next to gunpowder which has energy density of 3 MJ/kg. If you want increase it 5 times you're now in TNT territory (4.6 MJ/kg).
Would you prefer car that can do half the range or the one that goes further but literally has 500Kg of TNT under your ass ?
