Haven't seen that one. Many commercial vehicles are using supercaps for regenerative brakes, Mazda is starting to use them in consumer vehicles. Supercap makers claim they are extending retention times to match batteries.

That saying it is fun to see the videos on YouTube of the guy who replaced his car battery with a supercap....

Yes, I agree that 99 percent of new battery and energy storage technologies never make it to market. One reason is that the existing battery technologies are a moving target--always getting better. By the time a lab demo is fully optimized and ready for production--often a 5 year process--the existing batteries have improved even more. It would be hard to enforce a moratorium, however, because batteries and other energy storage technologies, such as supercaps, have become such an important technology to our modern mobile society. Supercaps, for instance, are being used in many applications today where they work better than existing battery technologies, such as regenerative brakes.

Moratorium

I'd like a moratorium on articles about battery technology unless someone has a technology actually going in to production. Elon Musk said something similar about pessimism over battery announcements:

"There are potential breakthroughs out there, but we have yet to see one — to see even a single example in our lab — of a cell working at the laboratory level, that is better than the one that we have or the ones that we expect to come out with. And so, my response always, when I hear about, um, electro-chemical breakthroughs, is, 'Please send us a sample cell.' That usually, well that always, has resulted in nothing coming."

The Japan Power Plus 'Ryden' double carbon battery is perhaps the best thing I've seen in a while but since they made their announcement about going to production in May I've seen nothing!

I see two very different roles for Supercaps-DrQuine


Yes, you are right on both counts. These Vanderbilt researchers, however, also claim that their architecture can hold its charge as long as many batteries, plus they are seeking to improve them, thus giving them at least a fighting chance at taking over the battery function for some applications someday.

Two Uses of Supercaps

I see two very different roles for Supercaps. First, they can hold the short term power buffer and spare the batteries the frequent charge / discharge cycles they normally experience. Secondly, Supercaps can be charged very quickly and then transfer the charge to the battery at whatever rate the battery can tolerate.  This would allow for quick partial recharges when power is available and then the charge could be gradually transferred to the device battery as you move on so the discharged Supercap is ready for another quick jolt of power at the next available recharging spot.

Hey Les, thanks for the link to:

Will BMW's electric turbocharger end turbo lag?

It explains the concept of electric assist to prevent turbo-lag very well and mentions how supercaps could help. Anybody know how the project turned out? Looks like it was being prototyped circa 2012.

I did not read anything about the wear-tear and crack related issues in phone cases or in other structures. I assume that super-capacitor will need to be protected in the similar way that of the current Li-ion batteries.

Mogulman, you're right on with the turbo app. There is development work already going on in this area. Several companies are working on just that idea, one brief discussion is at the following link: http://jalopnik.com/5855317/will-bmws-electric-turbocharger-end-turbo-lag

Note the use of motor/generator, acting as generator driven by the exhaust turbine, charging supercap and batteries, instead of using wastegate, when full potential boost is not necessary.

I've heard of lots of uses for supercaps in automotive, busses and trucks, but this is the first high-performance sports car app! Good call. Got anything else under your thinking cap?
