^^ Define "sucks" please? EG per volume or per weight... Also, watt ranges are we tapping about... eg "short range" aka "urban", or? PLUS, might "sucks" include battery-swapping? :wink:

I'd have to look up the exact numbers, but both volume and weight for a given energy are at least 2x more than lithium-ion. Close to lead-acid for energy density. But they are supposed to be quite good in terms of power density. High C rate for both charge and discharge. These seem ideal for standby power applications, like a UPS or a solar system.

^^ Hehe... "weight"... Was reminded just now of the results of the uphill racing in France in 1898:

An 1800 lb. vehicle "smokes the competition"... most of whom were a LOT "lighter". :mrgreen:

Like to see your dendrites "up close"?

Scientists get first close-ups of finger-like growths that trigger battery fires:

(Pic Cap:Lithium metal dendrite, taken with cryogenic electron microscopy or cryo-EM, shows that freezing has preserved its original state, revealing that it's a crystalline nanowire with six well-defined facets. Dendrites can pierce the barrier between battery chambers and trigger fires; cryo-EM is the first technique that can image them in atomic detail without damaging them. Credit: Y. Li et al., Science)

Starts:
Scientists from Stanford University and the Department of Energy's SLAC National Accelerator Laboratory have captured the first atomic-level images of finger-like growths called dendrites that can pierce the barrier between battery compartments and trigger short circuits or fires. Dendrites and the problems they cause have been a stumbling block on the road to developing new types of batteries that store more energy so electric cars, cell phones, laptops and other devices can go longer between charges.

This is the first study to examine the inner lives of batteries with cryo-electron microscopy, or cryo-EM, a technique whose ability to image delicate, flash-frozen proteins and other "biological machines" in atomic detail was honored with the 2017 Nobel Prize in chemistry.

More specific, the "eutectic" is a alloy that has no slush zone in solidifying in my understanding. It goes right from a liquid to solid. The iterdigitated part on a nano scale no less? Done by simple rolling out the clad metals! This has some huge implications IMO. Both metals are suitable for vapor dep also. :shock:

I agree. I also liked the muted tone of the announcement. No hype; just" it seems to work well, needs testing".

The supervising professor for the eutectic metals battery worked with the Li-ion inventor Goodenough in the 1980's... He knows a lot about the competing chemistries and he talks like an endless fountain of nanocomposition reactive chemistry speak. Here is cited by 50 articles in 2017, here is his review of current technologies. http://pubs.acs.org/doi/full/10.1021/acscentsci.7b00288

Yeah to a point. Even galvanized steel will corrode if exposed long enough to hard environment. Audi used to galvanize their cars, costly and only with moderate success. Net result also galvanized Audi will get eaten by rust, it just takes a little longer.

Even aluminum corrodes in salty winter clima. Not like steel where you can have rusting from the inside out if your out of luck and not as fast. But corroding never the less.

Hehe... ESB "Search found 133 matches: +Lamborghini"... In the news currently, stuff like Lamborghini Launched Terzo Millennio - NEW Lamborghini Terzo Millennio Electric Super Sports Car ... w/a YT vid:


... w/a description watt includes in part:
Energy Storage Systems
The strategy of creating super sports cars with uncompromising performance generates Lamborghini’s motivation to revolutionize the approach to energy storage, moving away from conventional batteries and investigating the potential of supercapacitors to equip the Terzo Millennio. This is in line with the application of low voltage supercapacitors in the V12 Aventador, which started five years ago. The next logical step is the development of a storage system able to deliver high peak power and regenerate kinetic energy with very limited influence from aging and cycling during the vehicle’s life, and with the ability to symmetrically release and harvest electric power. Thus, the collaboration with Prof. Mircea Dinca is aiming to overcome the limits of today’s technology and close the gap on conventional batteries’ energy density while preserving the high power, symmetrical behavior and the very long lifecycle related to supercapacitor technology. Prof. Dinca says: "The new Lamborghini collaboration allows us to be ambitious and think outside the box in designing new materials that answer energy storage challenges for the demands of an electric sport vehicle. We look forward to teaming up with their engineers and work on this exciting project". Innovative materials To support this revolution in energy storage systems, materials and their functions have to change, too. Lamborghini aims to further develop its leadership in the design and production of carbon fiber structures and parts, enhancing its ability to develop features and functions that take lightweight materials to the next level. For this reason, the cooperation with Prof. John Hart will investigate the new manufacturing routes for carbon fiber materials constituting the bodyshell of the Terzo Millennio, which will also act as an accumulator for energy storage and enable the complete body of the car to be used as a storage system. Prof. Hart says, “we are thrilled to combine our expertise in advanced materials and manufacturing with the vision and support of Automobili Lamborghini, and to realize new concepts that will shape the future of transportation.” The project also aims to combine the technology to continuously monitor the whole carbon fiber structure, both visible and invisible, with the concept of “self-healing”: the target is to provide the Terzo Millennio with the ability to conduct its own health monitoring to detect cracks and damages in its substructure derived from accidents. In this case a self-repairing process starts via micro-channels filled with healing chemistries, reducing to zero the risks of small cracks propagating further in the carbon fiber structure.
At press time, Lamborghini only said "No Comment" when asked if the Terzo will be easy to pedal. :roll:
