Cambridge Researchers Present Lithium-Air Battery Breakthrough (google.com)
Reuters reports on a tantalizing advance in battery technology described this week by Cambridge researchers, who have made large enough steps toward a practical lithium-oxygen battery to give a laboratory demo of their system. Commercially available lithium-oxygen batteries would be significant because they would
have the potential to deliver the desired power thanks to a high energy density - a measure of energy stored for a given weight - that could be 10 times that of lithium-ion batteries and approach that of gasoline. They also could be a fifth the cost and a fifth the weight of lithium-ion batteries. But problems have beset lithium-oxygen batteries that affect their capacity and lifetime, including troublesome efficiency, performance, chemical reaction and potential safety issues and the limitation of needing pure oxygen rather than plain old air. The Cambridge demonstrator battery employs different chemistry than previous work on lithium-air batteries, for example using lithium hydroxide rather than lithium peroxide. It also uses an electrode made of graphene, a form of carbon. The result was a more stable and efficient battery."
Some more about this research can be gleaned from Clare Grey's web page at Cambridge.

Lithium batteries have more than doubled in energy density over that period, while dropping in price. That improvement resulted from the research, summarized and discussed on Slashdot, that you are now dismissing.
If you don't want to read about leading edge scientific research, then please go chat on Facebook or some other mainstream forum, and leave Slashdot to the true geeks.
If you didn't have the memory of a goldfish you would have noticed that only a few of the many battery improvements written about ten years ago have made it to market at all.
Let me guess - you hate EV's. Friends and I have a wager about the EV denialist's last reason that they are an "utter failure".
My money is on the color they are painted.

If all the advances which were announced had played out as announced though they would probably have increased by a hundredfold or more.
Most research doesn't pan out. Not in batteries, or in any other area of scientific endeavour. That doesn't mean we should stop doing science. It also doesn't mean that we should stop reporting on science. If you don't want to read about science and technology, then GO SOMEWHERE ELSE. Go watch cat videos, or whatever. Good riddance. I am sick of all the SJW articles and other crap on Slashdot, so it is very annoying to read people like you whining about articles reporting real science and potential technological improvements. Articles on things like battery research are exactly what Slashdot is for.
Any government subsidies to the electric car industry pale in comparison to those of the petroleum industry. Not to mention the ICE auto manufacturers who DID go bankrupt, and were already bailed out by the government. Do you have any citation for Tesla about to go bankrupt?
It's like every other fake outrage for the self righteous, like BENGHAZI! where the hypocrtites get outraged over something that when they do it - its different, and its just fine.
You hate electrical cars? - the subsides for them are socialist, communist, atheist, gay marriage enabling hogwash, and the road to perfidy. You like your GMC Savana 3500? Then Oil subsidies are magically turned into laissez faire capitalism, and blessed by the invisible hand of the free market - Just like it says in the old Testament.
