Lithium-Sulfur Batteries Show Potential to Extend Electric Vehicle Range

....excerpt
Quote:
The new shield is made of graphite, a thin matrix of connected carbon molecules that is already used in lithium-ion battery anodes. In a lithium-sulfur battery, PNNL's graphite shield moves the sulfur side reactions away from the anode's lithium surface, preventing it from growing the debilitating interference layer. Combining graphite from lithium-ion batteries with lithium from conventional lithium-sulfur batteries, the researchers dubbed their new anode a hybrid of the two.
The new anode quadrupled the lifespan of the lithium-sulfur battery system the PNNL team tested. When equipped with a conventional anode, the battery stopped working after about 100 charge-and-discharge cycles. But the system worked well past 400 cycles when it used PNNL's hybrid anode and was tested under the same conditions.

Intjonn - wow, how not to make friends and influence people - good luck with your non-fossil project )
Manyboats - Accurate statement that the hybrid cars folks aren't wanting to save money but "show the way" in their opinion. Fossil fields do actually renew - visited with a Geologist that was in on the Ghawar oil field in Saudia Arabia back in the 50's - said the earth replenishes the fields all the time. He said there's more oil seepage from the earth into the ocean than all the Oil Tankers combined.
Like an old Rancher here in Owyhee county said - "Until I can afford to buy & drive a solar or electric one ton dually pickup to do my ranching, or there's a solar or electric Kenworth that can get my cattle to market, well, I guess I'm just stuck with that Danged Ol' Fossil Fuel" )

First off in the begining all heavy trucking in USA cities was done with electric. Petroleum became an off the grid alternative and eventually replaced electric as the mainstay method of powering heavy trucks.
Second, fossil energy dosen't renew itself what happens is crude seeps in to fill the void from surrounding oil shale. Fossil fuel is like corn when you harvest it you can grow a new crop on the same ground the difference being for corn it takes one season and for oil it take a couple of hundred million years.


The railroads learned in the forties that the cheapest way to move loads was with the use of electricity not diesel fuel or gas. All modern railroad engines use electric motors to provide motive power and Diesel generators to provide that power. Solar is on the verge of pushing the diesel generator into the back ground with the new technology currently in development. There is a European power boat manufacturer, cant think of the name, that currently makes an solar electric trawler with a generator backup. My numbers are not accurate but it can go 50miles on electric alone then the genset comes on. I calculated it was capable of almost 10mpg using solar and genset. I'll see if I can't find here is a link to the new larger version

GreenLine Hybrid 40 for sale, Hybrid solar powered powerboat, motor yacht from Sunbird

Here is a link to the model close to the earlier model i did my calculations on. Factory gives it a range of 700nm on 132 gallons of D alone no electric. My calculations were based on running in electric mode till its used up then on D for two hpours to charge the batts without any solar input then back on electric. This boat looks to be amazingly fuel efficent

Was there a gap in geologic time where trees didnt grow and shed leaves and animals werent born lived and died ???? Why do you think oil is not replinishing ??? No energy is ever lost it just changes form .

Railroads in the USA converted to diesel-electric locomotives primarily because engine maintenance was greatly reduced and multiple locomotives could be operated by single crews, reducing employment by millions. Fossil-based fuels remained the primary fuel source, however. European railroads are primarily powered by electricity without locomotive-carried diesel engines as the continent is fossil-fuel poor while North America is rich in coal and petroleum deposits.

thats true. You can sit and wait if you like but i don't have a few million years to sit and for my tank to be filled. Instead I will work to conserve fossil fuels when it dosen't interfere with recreation or grog

I drive a hybrid car (Volt, which I love, btw). I'm not trying to "show the way," save the planet or save money.

I have a teenage son, and I don't want him spending any time in Iran, so I do what I can to not buy oil from people who hate me.

Cotton,
I think we will be buying oil from the Middle East and elsewhere for some time to come. Most all people here will chose the route most cost effective for obvious reasons. Policy will be made by the bulk of consumers. Powering a trawler w electrons isn't practical but redesigning trawlers to be far more fuel efficient is practical and almost easy. Start w a sailboat hull and trawlerize it. I was actually going to do that some years ago and bought a Willard instead. A trawlerized sailboat would burn about half the fuel as my Willard and possibly less than that. Regarding the fuel efficient trawler burning far less fuel is a more practical route than trying to burn none at all. It's not like we're out of oil ... it's just less plentiful.

We may find a good alternative to oil energy before we run out of oil and how likely is anyone's guess. At this point oil is obviously still very plentiful and we need to use less of it primarily because there so many more people and those that never have used much oil are now becoming big consumers. Rightfully so too.

I have no interest in owning an electric trawler. And most here on the forum don't either. They actually like the rumbling diesel engine. Eventially the oil age will be over and electrons will be the essence of energy. But for now it's engines not motors.

As to your son there's no draft at this time. When I joined the Navy there was. But that was in 61. Tell your son to stay out of Iran and vote for people like Rand Paul.

Thanks for bringing that up again.

I remember this subject coming on another forum a few years ago, and I never had time to read it more thoroughly. It presents some interesting thoughts, ...particularly when you consider how the traditional fossil fuel explanations fail to account for oil on other solar system entities than just Earth.

Correct me if I am wrong, but I seem to recall that in the history of earth at the time of the dinosaurs there was very little tree growth?

You have not provided any links that reference actual scientific research just speculation. Any news release without references to the actual source of the data is speculation at best without any real scientific foundation. The research that was done to prove abiogenic oil all ended in failure. If you are a member of the American Association for the Advancement of Science, AAAS, like I am you can access real science and see some of the actual testing that was done, the results and procedures. Here is a link to there website used by most scientists. Home | AAAS MemberCentral

Yes, but keep in mind the fuel we use the earth created by subduction and heat, pressure, took some some two billion years and we have burned up most of it in 100 years.
One of the factors leading to the huge size of the dino's was the very high O2 content of the atmosphere at that time which was due mostly to photosynthesis in plants. No trees no O2. Today's air is 20.6% by volume if dry, during the jurassic period of the dinosaurs the air averaged 30% oxygen thats 1/3 greater than it is today. That wouldn't have happened if there were few trees.

The restrictions in moving anything is mass/inertia and friction/resistance – vs – energy available/applied. If these restrictions can be minimized then energy needed (from any source) to provide movement is minimized. If all friction/resistance can be removed, and momentum can be initially established via energy burst, then the movement of item can become virtually perpetual… e.g. planets in space.

So… being that humans are trapped on Earth with “mass/inertia and friction/resistance – vs – energy available/applied” as an every second occurrence there is great need to establish minimized weights and reduced surface frictions/resistances as sources for power and propulsion are also improved.

Not totally convinced that this was the 'method' of fuel creation,...or that is the thesis of these alternative explanations

I wonder if this is true also? Are there not alternative explanations for this higher oxygen than just huge numbers of trees?

I'm just asking, as I do not know, or remember from science/nature/history shows I am always attracted to.

PS: Do the ice core histories stored at the poles support the contention that oxygen levels were that much higher?
