Fast charge, space-saving and safe energy storage solution for automobiles, developed by researchers in Hong Kong.
The energy storage has long been the most critical challenge for electric vehicles or hybrid electric vehicles. There is a new trend of using supercapacitors to complement or even replace batteries as energy storage devices to improve the vehicles’ performance.
The Hong Kong Polytechnic University (HKPolyU)’s Body Integrated Supercapacitor enables manufacturers to make use of space in car body to maximize energy storage. Special ackaging and built-in power electronics technologies have been developed to produce supercapacitor modules with new structure.
As curved supercapacitor modules can be produced using the new technologies, supercapacitors can be integrated into car body panels, such as the roof, doors and the trunk lid.
In addition, new energy storage balancing technologies have been invented, which can reduce energy loss and the size of nergy balancing circuit in the systems of energy storage devices.
A series of related technologies were also developed, such as charging and discharging control, as well as connections with other energy storage system. Due to such developments, the Body Integrated Supercapacitor is compatible with and applicable in various electric vehicles.
Special Features and Advantages
• Supercapacitor in form of curved and flat modules can be developed to be integrated in different parts of the car body
• Energy storage components with high power density enable fast charging and discharging
• Energy storage system for electric vehicles using solely supercapacitors
• Hybrid energy storage system of electric vehicles using supercapacitors plus batteries (Li-ion batteries or fuel cells)
• The supercapacitor module is with rated capacitance 150F, rated voltage 50V, and can be in flat and curved surfaces with a physical surface area of 0.5 sqm and a thickness of 4 cm.
• Applicable to electric vehicles, and be integrated with various parts of the vehicular body
• Applicable to other cases where supercapacitor energy storage systems are required

Physicists of the University of Würzburg have made an astonishing discovery in a specific type of topological insulators. The effect is due to the structure of the materials used. The researchers have now published their work in the journal Science.
Topological insulators are currently the hot topic in physics according to the newspaper Neue Zürcher Zeitung. Only a few weeks ago, their importance was...
In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.
Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
