As amazing as this is, I wonder about more than just consumer electronics...what about automotive applications? Could this be the holy grail that allows EVs to surpass traditional gasoline cars in terms of demand? If I could drive back and forth to work for a week on a single charge as compared to a single tank of gas I'd be more than happy to jump on that wagon!

Everything staying the same, these batteries would also take 10x more time to charge. If they can charge and discharge faster than current batteries, we'll be seeing these things in more applications. For example, they could displace lead acid batteries in cars and UPSes if they can discharge faster.

What your wanting has more to do with solar cell efficiency, not battery capacity. A netbook needs around 30 watts to run, so unless you have as solar cell producing at least 28 watts the battery is going to need a substantial battery to keep the device running.

That we would have to see, lead acid batteries have been around so long because they are extremely durable, relatively cheap, and easily recycled(almost a 100% rate), not that I wouldn't like to see it, but outside of limited cases where cost is irrelevant and performance is important it will be hard to replace them.

Welcome to six years ago. Berkely had made similar announcements about the potential of silicon in batteries. However they have made no real advancements towards production. This is just another paper of little advancement trying to spur another round of funding.

LMAO. That day will be never. Assuming your light source was 100% efficient (no energy wasted as heat. It all went to light) and your collection source could collect ALL that light (absolutely impossible), you would at best collect about 13 Watts. It takes 13 Watts to run an Atom processor alone.

Or, you could put ten small batteries based on this technology into a single one of the same size as current batteries. Each small one could theoretically charge as fast as the older battery and if you charge all ten independently, then you can now charge and discharge ten times faster than before. It's more complicated and that might leave more room for failure, but it's something worth looking into, at least I think that it is.

A Tesla electric car can go up to 600 miles per charge. Electric cars don't have a problem with capacity (at least, Tesla cars don't, pretty much any other purely electric car is using ancient battery tech that is from the 70s and can't come close), they have a problem with charging time and cost. What I mentioned above might help the charging time problem (unless they already do something like that), but how do we reduce cost? Then we have to realize that we aren't really saving the planet by using electric cars when we consider where the electricity came from.
I don't know for sure about other countries, but the majority of the USA's power generation is from fossil fuels and nuclear fission plants. Switching the fuel from one fossil fuel being used in the car to another being used in a power plant (or Uranium) doesn't seem like much of an improvement, if even an improvement at all.
If we used modern nuclear fission technology, such as those newer thorium power plants instead of our old uranium power plants, then I think that we would be doing some good, at least from what I've read about them. There's also the option of using hydrogen instead of any other fuel too. Hydrogen is pretty much everywhere, burns well, burns clean (burning hydrogen gets you water vapor instead of pollutants), and hydrogen is very light.

As usual the promising technology will be commercialized after 10-15 years and will have upto 2-3x more capacity than the promised theoretical 10x.

And with future LED lighting, that won't ever work. 😀

Maybe, maybe not. LEDs often use much less power than other light emitting devices, but they do emit a lot of light for their power usage.

This. Because they will want to milk consumers and give better battery life in the next model of laptop or phone etc, thus giving everyone a "reason" to upgrade every 2 years.

Maybe, but this seems to be telling us that actual advancement has been made in the field; it's probably not just begging for more funding.

I'm in grad school developing a new kind of battery and I have a few things to say about this:
1) I assume this is Yi Cui. He is amazing.
2) There's nothing special about nanotech making batteries better. The key is making them cheap. I mean, this is good research but don't get so excited just yet.
3) A 10x improvement in anode energy density might translate to a 10% increase in overall battery energy density. This is because anodes are way better than cathodes right now, meaning they're already a much smaller part of the battery. Make them 100% smaller (not there) and the battery is still much less than double the previous energy density.
Sorry to rain on the parade. I'm not being jealous or anything. This is amazing research and I'd die for a publication like that. Just saying this doesn't mean iPhone 6 will last a week on a charge.

about 1 article per month since 10 years ago about batteries. yet we have the same old li-ion tech.
