Researchers at the Samsung Advanced Institute of Technology have developed a ball made from graphene (a single layer of carbon atoms) that could advance battery technology in a couple of ways. Batteries made from the new material could charge five times faster than current lithium-ion cells. Perhaps more importantly, graphene ball batteries could offer 45% more capacity.

In theory, a battery based on the “graphene ball” material requires only 12 minutes to fully charge. Additionally, the battery can maintain a highly stable 60-degree Celsius temperature, with stable battery temperatures particularly key for electric vehicles. In its research, SAIT sought for an approach to apply graphene, a material with high strength and conductivity to batteries, and discovered a mechanism to mass synthesize graphene into a 3D form like popcorn using affordable silica (SiO2).
 
Wake me up when they actually have a battery they can test. Until then, it's just a fantasy (to be polite).

Really, because a number of technologies I would file in that category have showed up as actual products. Probably the least altered from teh press release is the toshiba SCiB tech. Touted in 2009, we are getitng a revised version of the product they just announced in 2017.

Litium polymer showed up, it's what permitted all the weird cell form factors we see in products we use every day now.

Yeah, there are a lot of very premature announcements of tech, but there's plenty that's real and in production. You just don't see it because what it brought to the table isn't enough to cause a massive wave of change in the end consumer market. If things like local energy storage and EVs become popular, then the scope of cosumer facing products will broaden and I suspect more of these announcements will seem more practical and meaningful to retail level consumers.
 
45% larger fires, 5x faster cool. Samsung Galaxy Note 10 we bring the fires to you.

I believe that was more due to patents than anything and why Tesla was stuck with inefficient (space wise) 18650s until this year. One company owned the patents for other sizes/types of cells and this applied across the board for various chemistries too from what I understand, it has recently expired or about to...
Toyota had bought rights to use it, hence their Hybrid batteries being half decent and large cells.

Yeah, pretty much. I'm sort of over these articles because nothing ever happens. Mainly because they want to sell more batteries and devices. The quicker they die, the quicker we have to replace devices they built into.

Not exactly new though, on one hand you have research they simply show what can be done. They don't show the economics of it, the feasibility of making them en mas, they simply show what can be done.

I do find it funny thought that whenever someone comes out pro-nuclear power they also basically talk about what the research has shown can happen with nuclear power but no one does any of it.
 
Been waiting for this to hit the shelves since I read about the breakthrough back in 2012. 5+ years later, still waiting....

Waiting for what? This particular technology?

Looks like energy density of batteries have roughly doubled in the past 10 years (assuming the graph is accurate), that's a 100% increase in 10 years.

HINT: its not.

its total BS. More like an economists prediction. i.e. wishful thinking in whatever direction the wind is blowing at the time.

you can print text with official sounding names and URLs on them all day long, doesnt make it valid (or even in context).

Here is another one.

Even if we have no large breakthroughs, it looks like lots of incremental improvements will be enough to have batteries do what we wish, get cheap enough to replace gasoline cars for the masses. It's just a matter of time. And battery research on the chemistry and materials science side is not going to abate. Smartphones, tablets, laptops, cars, trucks, planes, etc. etc. The global demand for ever more dense batteries is not going away, and that will drive investment for research and improvements.
