Supercapacitors

For the first time, a team of researchers have formulated inks using the 2D material MXene, to produce 3D printed interdigitated electrodes.

It is nonsense to forecast pure electric cars costing the same as traditional ones, then life continuing much as usual. The up-front price of pure electric cars will be dropping below that of internal combustion engine ones around 2025. The fundamentals are now clear. Short range electric cars will continue to sell badly because of range and financial anxiety: their resale value after three years can be down 80%. 200 miles/ 320 km is the tipping point where resale value can be only 40% down on purchase price. See the IDTechEx report, "Electric Vehicles 2020-2030" for the full picture of 100 categories of electric vehicle EV by land, water and air.

IDTechEx's Dr Peter Harrop looks at five types of EV now.

From Day two we highlight a presentation on a new additive composite technology used initially to optimise drones and on a new way of more precisely tailoring porous materials for energy storage, energy conversion and other applications.

Fork lift trucks are almost all induction because reliability and affordability trump performance here. Their batteries are rapidly going lithium-ion for something less toxic and nearer to fit-and-forget but there is no similar issue with the motors.

Shortage of lithium-ion batteries is probable. Too few gigafactories. Too many burning batteries: factories shut to sort out their problems. The US-China trade war cuts off materials. Inadequate lithium or cobalt mining.\r\n\r\n

Is it all about cars and extrapolation? Not anymore. The unique new IDTechEx report, "Lithium-Ion Batteries for Electric Vehicles 2020-2030" avoids mindless extrapolation. It uses fundamentals to predict huge changes in the electric vehicle business and the way these vehicles store electricity.

Researchers have developed a new and inexpensive method to fabricate thin film electrode materials for supercapacitors that produce higher power at a lower cost.
