The Argonne National Laboratory in the US has essentially cracked the battery technology for electric vehicles, discovering a way to raise the future driving range of standard EVs to a thousand miles or more. It promises to do so cheaply without exhausting the global supply of critical minerals in the process.
The joint project with the Illinois Institute of Technology (IIT) has achieved a radical jump in the energy density of battery cells. The typical lithium-ion battery used in the car industry today stores about 200 watt-hours per kilo (Wh/kg). Their lab experiment has already reached 675 Wh/kg with a lithium-air variant.
This is a high enough density to power trucks, trains, and arguably mid-haul aircraft, long thought to be beyond the reach of electrification. The team believes it can reach 1,200 Wh/kg. If so, almost all global transport can be decarbonised more easily than we thought, and probably at a negative net cost compared to continuation of the hydrocarbon status quo.
The Argonne Laboratory in Chicago is not alone in pushing the boundaries of energy storage and EV technology. The specialist press reports eye-watering breakthroughs almost every month. America, Europe, China and Japan are all in a feverish global race for battery dominance – or survival – and hedge funds are swarming over the field.

The @argonne National Laboratory and @illinoistech have achieved a breakthrough in the energy density of battery cells that could push EVs beyond 1,000 miles on a charge, and potentially, eventually, power trucks, trains and mid-haul aircraft.https://t.co/qZOFi28aOW
