Batteries for EVs
I wonder to what extent that's actually newsworthy though. It's basically: 'building a factory to mass-produce a complex technical product takes very considerable time and investment and, once built, the maximum output of the factory can't easily be increased'. Shock, horror! How long does it take a car maker, Porsche for instance, to design a complete new engine range and then finance and build a plant to build those engines? Several years and several €B I would guess.
I think anyone can see that it's going to take 5-10 years before the supply of batteries (and other parts like high-tech motors) for EVs gets properly into balance with trends in demand. It's probably also another reason why EV battery technology is not going to evolve too quickly in practice - the limiting factor is the mass production capacity and not the ideas or lab-scale demonstrations.

Researchers at Glasgow Uni have developed a liquid changing system - rechargeable in same time as refuelling a petrol.
