Lithium the element hasn't changed in a loooooooooong time. We still have only one periodic table to use amongst all of us.
Electric battery research started way before that. First full scale electric car was developed in 1830, 50 years before gasoline engine was even invented. One problem with the batteries is they need to convert the chemical energy directly into electrical energy and the chemical reactants used are all stored inside the battery cell. If the same limitation were imposed on gasoline, the aircraft would need to carry about 15kg of air for each kilogram of gasoline, no wonder lithium batteries energy density is 40 times less than fuel. Fuel cells might be a solution, but they have their own problems. Batteries are so liked because the only thing you need to do is recharge them, electrical network is virtually everywhere. Forget about hydrogen fuel cells, hydrogen is hard to store and expensive. Maybe a fuel cell using some sort of synthetic fuel is the future.We have just started battery research
It ain't. The sum total of data stored might be increasing at about that rate, but unless we think cat videos and twitter tweets are knowledge equivalent to the writings of Shakespeare, Euclid, and Newton, then we can't say knowledge is doubling every year.With the sum total for mans knowledge, doubling at a rate of every year now
Nope, I am saying it took us a long time to get to lithium based batteries that got us the big boom in energy density. I am just not sure where we are going to go to next for the great orders of magnitude energy density in batteries that people are alluding to. Batteries aren't like microprocessors. They aren't doubling in capacity every year and a half.Are you inferring , that Lithium is the only element that will ever
be capable of supplying, light battery power, in the future ?
I have a lot of faith in humans ; i'm almost certain that a really
good solution for light batterys , will be found , (soon). Hopefully
a combination of elements that are some-what Stable, when
fully charged ! With the sum total for mans knowledge, doubling
at a rate of every year now ; i feel quite confident in what i just wrote
Yup. They're selling an kit for an airplane that has never flown. That's the usual formula for massive disappointment.
There are a couple of generations now that think they can create their own truth just by repeating a lie over and over. Unfortunately, it doesn't work. Reality, which includes physics and chemistry and finance, MUST be addressed.And wisdom? Look around, it seems to be in decline.

I will say it again: We've been promised the moon for many decades. We old guys are familiar with the claims of the press, including the old Popular Mechanics and Popular Science and Science Illustrated magazines. Fantastic airplanes and flying cars and revolutionary engines in just about every issue, my whole life. VERY few of them ever achieved actual existence. Journalists have to make a living, along with their employers, and they will hype just about any wild idea to sell copy.

There's a difference. Speedboat. "Science Fiction" has the word FICTION in it, meaning it was sold as fiction, not imminent reality or possibility. A lot of "revolutionary" stuff we read about these days is Fiction sold as Fact. It's maddening, because people believe it and put down fat deposits for, or make investments in, stuff that never materializes. Basically, a scam.
A few carbon atoms will compact the hydrogen and make it easier to contain.Hydrogen has a very high mass energy density but a low volumetric energy density even in liquid form, so you need really big tanks... and the required pressure means really big HEAVY tanks. And even then it's difficult to contain, the molecules are so small that they tend to leak through anything.
