A new supercapacitor based on manganese oxide could combine the storage capacity of batteries with the high power and fast charging of other supercapacitors, according to researchers.

As demands for lighter and smaller wearable devices and high functional IoT gadgets rise, there is a growing need for new technologies for power collection, storage, management.

A tiny microsupercapacitor that is as small as the width of a person's fingerprint and can be integrated directly with an electronic chip has been developed. This has attracted major attention as a novel technology to lead the era of Internet of Things since it can be driven independently when applied to individual electronic components.

Researchers demonstrate robust supercapacitors that still work when stretched to eight times their original size.

While at the proof-of-concept stage, it shows enormous potential as a portable power supply in several practical applications including electric vehicles, phones and wearable technology.

Vehicles for construction, agriculture and mining CAM have become one industry served by giants such as Caterpillar, CNH Industrial, John Deere and Komatsu but also small businesses making the new requirements such as drone systems and weeding and mine survey robots.

NAWA Racer is inspired by 1960s café racers but is powered by a world-first 'hybrid' battery system, which combines next-gen ultracapacitors with lithium-ion offering ten times more power and five times more energy than existing ultracapacitors.

A smart contact lens with a rechargeable supercapacitor power source that can be charged up wirelessly could be used to track a wearer's health, without compromising on comfort.

CAP-XX announced it will acquire CAP-XX licensee Murata's supercapacitor production lines, relocate them from Japan to a new factory in Sydney to arrive in stages between March and June 2020, and begin producing Murata's three supercapacitor product families in Q3 2020. Murata will also assist in introducing CAP-XX to its customers.

The collaboration between Automobili Lamborghini and the Massachusetts Institute of Technology has produced a major initial result: a patent for an innovative synthetic material that will serve as the technological base for a new generation of supercapacitors.

Supercapacitors, electrical devices that store and release energy, need a layer of electrolyte — an electrically conductive material that can be solid, liquid, or somewhere in between. Now, researchers have developed a novel class of liquids that may open up new possibilities for improving the efficiency and stability of such devices while reducing their flammability.

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.

Presentation by Dr Peter Harrop to BIT Advanced Materials Conference Osaka Japan 23 July 2019

Dr Peter Harrop explores Toyota's progress with pure electric vehicles in 2019.

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.

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.
