Thought i would share this article, glad batteries are catching up...

First paragraph

"Apr. 16, 2013 — Though they be but little, they are fierce. The most powerful batteries on the planet are only a few millimeters in size, yet they pack such a punch that a driver could use a cellphone powered by these batteries to jump-start a dead car battery -- and then recharge the phone in the blink of an eye.

    Could this be the answer to cheaper electric car technology? The article does go on to say that there is a plus and a minus side to the technology :smile:

    No, it's not.

    The Global Lithium reserves are not large enough for a complete electification of all cars.
    (Not unless that battery system uses less Lithium in the cells)

    no, the solution is Zinc-Air...

    300% better efficiency, lower price...

    Hmmm. a shortage of Lithium reserves??? That bodes well for NiMH to fill in the demand. Nickel is not in short supply. It doesn't burst in flames. And the rare earths that are required are plentiful.

    Zinc-air?

    We're hearing about such breaktroughs each year. However, I don't see any significant advantage in terms of volume/capacity over the last decade.

    It seems like recharging /replacing the Zinc air batteries is a hassle. They do out perform the other batteries, they get significantly hotter, and the supply for them is through the roof (unlike Lithium-ion).

    I don't know how many people here have heard of Tesla but they are a a emerging electric car company in California, and they seem to use Lithium-ion.

    This is exciting technology. But I didn't read anywhere in the article that the new cell offers greater energy density over existing lithium technology. It simply implies that the new design has vastly lower internal resistance, so maximum charging and discharging currents can be much higher.

    Without greater energy density, a car powered with these would still have the same lackluster range, albeit you could recharge a lot faster. So if a five minute whistle stop would get you another 100 miles down the road, it might actually turn the tide on electric vehicles.

    But like Gadgetman points out, there's really not enough lithium to go around. Perhaps the same 3D electrode technology could be applied to another cell chemistry.

    Electric cars has suffered from lackluster range and slower refueling ever since the first one rolled off production in the 1890s in France.

    It certainly has helped that battery technology has improved energy densities, but it seems that the higher you go in energy densities, the more that batteries behave like gasoline in terms of storage and handling.

    The fuel cell still holds a lot of promise as it offers high energy density, low polution, fast refueling. And the hybrids offer refueling autonomy. I just can't seem to put all my hopes on a better battery.

    how is 300 miles in 4 hours Slow !? that is 1.25 Miles a minut to charge .

    Yea I get it . you cant go from LA to vegas . so what ..... for 90% of us the current EVs do just fine as day car replacements .

    Unless you work as a timber cruiser in the woods of Oregon and take a wrong turn.

    Getting stuck in the Mojave between LA and Las Vegas could be fatal.

    And for the 90%, we could all take a bus to work and rent a car for other uses. But individuals really want that personal autonomy.

    I think the 90% would rather drive a car to work (and the mall, corner store, doctor, dentist, etc.) and rent a car or take a bus, plane, or train to go to Vegas. A small electric "town car" could easily do that for most city dwellers on a single charge. Unfortunately the automakers seem to be doing the same old same old. Over priced ridiculous designs so they can convince the public and politicians that electric cars are impractical.

    Exactly !


    No one ever said every one has to own a EV . bull iLl bet most of us only Need a EV for Our day trips . ans 18 K 100Mile range is Very reasonable.
    My parents know a guy up the street whom owns one and pays under 60 bucks a month for the lease..
    so 60 USD for the car and
    """According to Consumer Reports, as of December 2011[update] the Nissan Leaf has an out-of-pocket operating cost of 3.5 cents per mile""
    So lets take that 100 Mile range and we get 3.5 USD per 100 Mile charge //// Less then subway sub per 100 miles ...

    OK so you Drive 30 Miles to work and 30 back that is 60 Miles .. 3.5 * .60 = 2.1 USD a day to drive and there is 31 days ish in a month is 65.1 USD a MONTH to commute

    125.1 USD a month is your outta pocket commute cost a month for a LEAF


    Lets take a 28 MPG car . OK gas here is 3.8 USD a gallon and that car takes 13 C a mile to run 8.14 USD a day to commute
    31 days 252 USD a MONTH to just FIll Er up ! JEEZ!!!!!!!!!

    Oh and Lets Lease a car too while we are at it . 100 bucks more a month

    that is 352USD per month to commute in a gas car ,,

    the LEAF is .35 the ( 35% the cost of owner ship per month as a gas car )
    so unless you are the poor sap whom Really really Needs more then 100 Miles a day ,
    You would be a fiscal failure to Buy a 2ed Gas car to just """" go to work and back "


    I REST MY CASE .

    Why does it have to be a town car with 4 passenger seats? The electric tuk--tuk that is available in the US would double the available parking. Electric motor scooters would quadruple the available parking. Insurance premiums are lower too.

    Going to electric vehicles is going to be a life style change. So why not enhance as many aspects as possible?

    I do admit that late at night and on the road alone, a woman is better off in a locked car than on a motor scooter or in an open vehicle.... just about anywhere in the world. But vehicles are really just a transportation expense for most of us and less expense would overcome barriers to acceptance.
