We seem to see a "breakthrough" technology in battery design and solar cell efficiency every few weeks. I can't wait until we can make use of these new technologies. Affordable electric cars with 1,000 mile ranges, computers with 24 hour batteries, and off-the-grid home power systems have been a long time coming.
if the gold cathode is in the battery - that might be a tad expensive
Plenty of other developments reported on the theme of increasing the surface area of the electrodes using nanotechnologies (eg http://www.bbc.co.uk/news/technology-22191650)
Not sure about the comments on fragility - surely at that scale the viscosity of the electrolyte will considerably cushion any shock as long as the plates at either end are held rigidly with respect to each other?
anyone notice "Amprius is manufacturing its new batteries in China". So was this from government funded research so we can help China create more jobs ? This is only enriching the individual researcher and not return on investment to the American taxpayer.
I agree with you, plus I don't understand how energy density is increased 10x with low resistance wire, seems like that would help more on peak power (or the carbon solution is really realy crappy eating up to 90% of total energy. If it is power, then the benefits are much more limited. Hmmm!
The caption does say power density, but it quotes an energy density of 4200 mAh/g. I suspect that whoever wrote the caption isn't an engineer or physicist.
I predict that there will still be people who have difficulty keeping their cell phone charged :-)
A Book For All Reasons Bernard Cole1 Comment Robert Oshana's recent book "Software Engineering for Embedded Systems (Newnes/Elsevier)," written and edited with Mark Kraeling, is a 'book for all reasons.' At almost 1,200 pages, it ...
