A better battery will increase the useful range between recharges, sure.
But the energy still has to come from somewhere.
A power plant of some sort; coal, hydro, nuclear...
That can not change.

Yep, thats basic physics. You cannot get more out of something than you put in it.

Driving range is just one problem with electric cars. Recharging time is also an issue for consumers. Instead of a 10 minute fill up at a gas station, electric cars would require hours of recharging. This might not be a problem if you are driving to work and can recharge there, but consider driving your electric car on vacation, making deliveries or even a weekend trip. Long recharge times could be a nightmare on the road. Imagine pulling into a recharge station and waiting hours in line for your hours long recharge.

I've wondered for a while if there was a market for a small trailer mounted generator for those long trips.

Anyone who ever watched the original Star Trek series knows that the early starship warp drive reactors were powered by lithium crystals. The series was set in the 23rd century, so we still have to wait about 200 years until lithium crystals become common as a power source on starships. This is not to say the crystals will not be used earlier in other systems.

My flashlight is powered by the 18650 battery.

I have been told that the Tesla is powered by the very same battery, but several hundred of them.

Interesting article.

If they can put a man on the moon, why can't they invent a cheap, sustainable car battery with a 500+ mile-range that can also go faster than the speed of light?

Electricity is like government money to leftists. They think both appear out of nowhere.

Attach a lightening rod to the roof of a car to catch lightening bolts and somehow convert that energy to usable energy, connect to the drive train and you'd have almost free energy.

I suppose I'd better tell you, I'm not serious about that, lest you think I'm a liberal.

Driving range is just one problem with electric cars. Recharging time is also an issue for consumers.

One of the biggest problems I see is the environment vehicles have to operate in. Just in this country, we have regular seasonal temperatures that vary by well over 100 degrees. A battery that works just fine at average room temperature generally doesn't work all that well 50+ degrees above or 50+ degrees below, both of which are common. Where I live (NE Ohio), we're seeing regular single-digit temps right now, but summers in the high 90s would not be unusual, and we've seen extremes past that at both ends some years.

Of course, to be sure, gasoline and diesel vehicles aren't exactly happy at those temperature extremes either, at least at first. But once started, the will generally operate reliably, predictably and without a significant performance penalty. Not so much so with traction batteries.

I don’t know a whole lot about electric cars, but have read that ghere is a move to stadardize removeable batteries that can be changed in minutes ar a charging station. I would expect a noticable fee for such a service.

Not the same, but similar.

http://www.greencarreports.com/news/1084682_what-goes-into-a-tesla-model-s-battery—and-what-it-may-cost

Tesla: thousands of cells

In contrast to every other automaker, which use specialized large format Li-Ion cells, Tesla’s battery pack is made up of thousands of inexpensive commodity cells similar to those found in laptops.

Unlike automotive cells, these cells are produced in the billions, subject to the fierce competitive pressures that are a signature characteristic of the computer and consumer electronics industries.

Even including the overhead of the pack enclosure, connections between cells in modules (and modules in the pack), sensors, and circuitry, Tesla likely has lower pack costs than any other maker of plug-in electric cars.

Simplifying a cheap cell

But for the Model S, Tesla redesigned what was already a relatively simple cell to be much less complex, and to have a much lower manufacturing cost—largely by removing expensive safety systems built into each individual cell.

When used as a laptop battery, each cells requires a safety mechanisms to prevent fires. But in a large, electronically-controlled, liquid-cooled battery pack like the one used in the Tesla Model S, having certain safety features on each cell would be redundant.

In this case, the company’s cell design eliminates the relatively complicated battery cap of the commercial cell, and replaces it with a simple aluminum disk.

Intumescent goo

Having radically simplified the cells, Tesla then designed simple and inexpensive fireproofing systems into its battery pack. Among many innovations, Tesla appears to have incorporated a form of intumescent goo that it sprays onto the interior of the pack to aid in fireproofing.

When exposed to heat, a chemical reaction occurs in the goo that helps cool the heat source, while simultaneously forming a fireproof barrier to protect the rest of the pack.

I believe Scotty said they wer “Di-Lithium Crystals” Captain. And sheez, they were always on verge of blowing up or something.

Quick change battery packs to swap out.

Capacitors. Really big capacitors!

Txchnologist, an online magazine sponsored by General Electric, talked to team member and aerospace engineering PH.D. candidate Ross Cortez, he said “The fusion fuel we’re focusing on is deuterium [a stable isotope of hydrogen] and Li6 [a stable isotope of the metal lithium] in a crystal structure.”

“That’s basically dilithium crystals we’re using,” he said.
