Supercapacitor E-Bikes

[lenny]

"Made from aluminum and coal, supercapacitors are cheaper to make and use fewer rare earth metals. Ostrichoo’s bikes have a claimed 2,200 charge cycle, which is nearly twice that of a standard lithium battery-powered e-bike. That said, the supercapacitor-powered bikes have a notably shorter range of about 70 kilometers (44 miles) on a single charge."

Total twaddle.

Anyone who thinks you can power an e-bike or any other current hungry application with a super capacitor of ANY sort just doesn't know anything about physics.

Pi-Pop – the e-bike without a battery

Whilst electric bicycles don’t cause as much harm to the planet as, say, a two tonne electric car, the fact is that lithium batteries and other manufacturing processes involved in producing e-bikes do have some environmental impact. Adrian Lelièvre, a French entrepreneur behind the Pi-Pop...

Tom Stanton built one on his Youtube channel. IIRC, it did about 100 metres with full charge.

Yes - I remember that video. It kind of makes the point I wanted to make above about how useless they are as a source of energy for propulsion - except for a VERY limited time.

Our Argos e-move folders seem to have a super capacitor in the rear light. When we apply the brakes and the brake light comes on brightly, some of the current switched to the brake light is used to charge a super capacitor and this slowly discharges into a not very bright red LED which continues to glow as a rear light. It isn't terribly bright, and if you were on a long dark ride which did not require much braking it would go out pretty soon - probably in about three minutes. I have fitted a red blinkie on the back of mine for the very occasional time I might be riding in the dark.

Did you notice that he doesn't mention range? That's because the super capacitor will drain in a few meters. Even my Argos e-move folder has a range of 18 to 20 miles from am 8.5 Ahr battery. My other bike with a three year old battery can still take me 40 miles or 30 if I do barely any work. That gimmic bike will barely get you down the street.

An Ultra-High-Energy Density Supercapacitor; Fabrication Based on Thiol-functionalized Graphene Oxide Scrolls
"In the voltage range from 0 to 4.0 V, a supercapacitor fabricated with NTGS powder exhibited high energy densities (206 Wh/kg, 59.74 Wh/L) compared to previously reported values (85–100 Wh/kg), and comparable to those of Li-ion batteries "

An Ultra-High-Energy Density Supercapacitor; Fabrication Based on Thiol-functionalized Graphene Oxide Scrolls

Present state-of-the-art graphene-based electrodes for supercapacitors remain far from commercial requirements in terms of high energy density. The realization of high energy supercapacitor electrodes remains challenging, because graphene-based electrode materials are synthesized by the chemical...
