Energy Storage

Carbon nanotubes can be mounted upright in dense forests to maximise porous area in elecvtrodes for supercapacitors, supercabatteries and, it is thought, for some batteries as well.

Researchers at Rice University have refined silicon-based lithium-ion technology by literally crushing their previous work to make a high-capacity, long-lived and low-cost anode material with serious commercial potential for rechargeable lithium batteries.

At the "Utility Vehicles and Buses" session of the eCarTec conference in Munich, Dr Ulrich Piotrowski of Daimler EvoBus revealed more about the high stakes game being played by many of the major automotive companies in introducing fuel cells as range extenders in on-road vehicles.

The term printed electronics is shorthand for printed and potentially printed electronics and electrics. It is an enabling technology like paper or the wheel and, like them, its applications are now taking unexpected turns.

At eCarTec in Munich, Prof Dr-Ing E. Jobson of Volvo Bus Corporation illustrated the contribution of energy harvesting in electrodynamic braking as part of the many other improvements over the years.

Acetonitrile is used as electrolyte in some EV batteries and most EV supercapacitors. It is a very nasty substance, being volatile, flammable, carcinogenic and, according to recent research causes birth defects.

The large urban bus has gone from having a very large, noisy, polluting piston engine to parallel hybrid, series hybrid with slightly modified internal combustion engine, series hybrid with specially designed small internal combustion engine and then pure electric all in the space of ten years.

IDTechEx's Chairman, Dr Peter Harrop provides a snapshot of his insight into eCarTech held in Munich this week.

Cellergy, manufacturer of Electrochemical Double Layer Capacitors, has just introduced its new CLK series, for extended operating temperature applications in the range of -40° to 85°C.
