> 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.
I have very close to buying a new car an EV at that. I do worry that in the next few years we might have a new wave of battery technology that'll make me wish I'd waited.
I personally cannot fathom why, outside of pure performance, anybody would purchase an EV instead of a Hybrid... you get better range, it's (probably) better for the environment (mostly because the batteries can be much smaller).
Go test drive a Toyota Crown [0] — it's 30mpg hybrid with 345hp
For me its simply the ride feel and the tech within the car.
Full EV's whilst not having great highway mileage, still get excellent mileage compared to a full ICE when in and around the city. If you have a plug in hybrid, I don't really see the point in having to charge a battery and put petrol in the car.
I don't care so much on the environmental side, however for a hybrid you still have an engine that consumes petrol, as opposed to just having a larger battery. Which is then a petrol engine, plus a transmission and clutch which require maintenance just like any other ICE.
Lastly here in Australia a full charge only costs around $20-35 as opposed to around $80-90 for a full tank of petrol.
>plus a transmission and clutch which require maintenance
None of the Toyota Hybrids have either (instead, a Pn10 [n=6,7,8] orbital gearbox [0]), but they do have the ICE maintenance requirements. Conversely, the inevitable battery replacement is much less expensive on a hybrid.
Fun fact: the main electric rotor redlines at 17,000+ RPM

You can do either/and, depending upon driving style. For example, if you mostly drive locally you probably don't ever need to gas it up — but be sure to use ethanol-free fuel if so (to not gunk up fuel system).

But you can never know.

For reference, I drive a 209hp Camry [51mpg+] =P

Now I see why ZF two-speed transmission for EVs exist
