> While conventional lithium-ion batteries are limited to a maximum range of 600 km, the new battery can achieve a range of 800 km on a single charge

I know it's a mass-market site but this level of reporting is just insulting. Here are the actual numbers from the paper:

> We demonstrate lithium metal batteries achieving a 5–70% state of charge (SoC) within 12 min over 350 repeated cycles at a 4C (8.4 mA cm−2) charging rate, as well as high-energy designs delivering projected energy densities of 386 Wh kg−1 reaching a 10–80% SoC within 17 min over 180 cycles.
