    electrical question

    Kanode has remarked that vanadium will operate at 5 volts vs 3-3.5 for current batteries.

    Who/ what benefits from this? EV's, power tools, laptops and why?

    Also what about the 50C comment? Who/what/why?

    • Many existing industries will become obsolete and may new ones will flourish.

      You traveling in space will occur with us having a fuel tank that hold 60 gal SUPER? lol
      Its going to be with some type of molecular cell. Batteries are molecular cells

      At the end of the day Team VLNC and the Artful Dodger has to want for its current stock holders succeed. Just how the game works, "the market is not rationale" is a nice way of putting it.

    • At the end of the day all you need to know is the following: In this world the largest companies in the world with LARGEST market cap are ENERGY Companies. They don't want to loose the ability of digging a hole and making ALL pay for what comes out of the ground for an absurd price.

      It is like almost as bad as me thinking in 1984 who is going to buy WATER!!?!!

      Technically if we all lived in an area with oil we can have micro oil mills and create our own energy.

      These heathens since with their large empires would rather keep destroying the earth, digging holes and fracking. However they argue they do minimal damage (whatever) ONE NEVER leaves the area better off as opposed to as if they had never entered the area. Newton's principles can be used describe some of this.

      Now all this energy available to us all around in the form of Wind, solar and Tidal can finally be stored perhaps more efficiently for use and the cost associated with is fabrication and maintaing then the fact all 3 of infinite in a sense. The earth is finite space and we have a finite amount of oil that is here. Wind, Solar and Tidal when that runs out we ALL RAN OUT. A concern for energy will be no longer an issue since we are extinct then.

      Its not like we don't have an infitismal amount of energy available to us it is we haven't developed or the TITANS of ENERGY haven't allowed it so. What are they going to do with all the oil and how will they have a Trillion dollar monthly industry; weekly for all I know. You get the jist.

      Obama all the knocking I do on him is cultivating such an industry.

      Big OIL obviously having realize that he has perhaps started a dominoe effect and now they are starting to look like the bad guy finally to ALL has started campaigns. First it was lets use Natural Gas! Why? Because we own it and we can sell it to you. How is XOM going to make money if you buy a wind turbine and solar roof and drop in another source if you live next to a body of water and then become self sufficient in the energy you use. Please buy our Natural Gas otherwise your Un-American! Those DB are not Un-American when they build facilities in foriegn countries?

      Anways the entire thing can be put into this equation:

      World needs Energy to move the big motor = Use Oil from Big 6 or find something to be able to STORE the plethera of energy around us?

      That is why a battery is so powerful. You buy a battery, the mail man ships it to you or pick it up at a store.

    • The ratio of 5 to 3.5 is roughly 42%. A game changer. Did you understand that A G A M E CHAAANGHHHERR!! Do you see why all of a sudden the Oil Industry has started putting Billions of dollars in place to set up the infrastructure to using and harnessing Gas since Natural is cheaper 25%? cheaper then Oil. I thought it all come from the ground? Anyways, thats not what my response is about.


      "Cell phones don't need "more power" they need higher capacity. They operate fine at 3.7V. Increasing the voltage doesn't increase the capacity. Cell phone batteries are a commodity. No one will want to add cost by needlessly increasing the voltage."

      The above statement misses the big picture Lil RADS isn't working a phone anymore he is working his calculator, accessing his cloud and data center emails, surfing the web, his GPS is own whatever the countless apps your hand held uses. Yes eventually when nano techonology kicks in we might do away with it all but we can make a few pennies if the U.S. Gov't and the rest of the world is serious about alternative energies and all energy needs to be STORED! STAAAWWWWREEEEED!! did you get that STORED.


      " Voltage has nothing to do with energy density. "

      After that statement if you were next to me I would demand you buy me a beer and ask you when did you become a BATTERY ENGINEER? This is what they mean by in my industry a little bit of knowledge can get you KILLED. ( don't get all nasty, I am having some fun with you)

      After semi reviewing my response I realize after the above statement I go off the deep end.(Goodbye is still incorrect.)

      In electronics such as phones and microchips, voltage is simply high or low, a zero or one oscillating back and forth. This oscillation is described using terms as Voltage and Frequency. Basically this becomes the ability for a battery to discharge Voltage and Current which is manipulated by the user thru the interface of a key pad or in a motor its called a variable frequency drive. You can just basically operate your device longer because you have a supply that lasts longer hence longer battery life.

      Eventually you and your pal can't get your car started if you MacGyver or Double EE with some cables eventually in the future you can take all 3 of your cell phones and use it boost the engine to start your ICE motor crank as opposed to calling for a toe or pushing it down a hill and jumping the clutch.

      Any further explanation would be me doing a EE405 Design class...lol. Then we are designing UAV Predators then piggy backing waves upon waves and compounding modems and demodulators and selling it on the black market to the highest bidder. They never let me build remote detonators in any of my electronic labs...lol.

    • Yes.

      P = V X I aka Kirchoff's law...aka P = Watt = Volt*Amperes

      Though Volt Amperes (VA) is larger then a Watt (W) since

      VA= Watt * Power factor

      Powerfactors =0.8

      hence

      VA=Watts *0.8

      Voltages can be manipulated for many different reasons for different results.


      " Also, the supporting hardware such as electrical connections, pack size and the battery management systems (BMS) gets simpler which brings cost down. Less welds, less circuitry to monitor things like individual cell temp. and voltage etc". You can relate this statement with the two statements for UPS and Cars below.

      For Uninterrupted Power Supply you will need a small footprint of the device itself. In turn you will need smaller wires for connection which are made of copper and cost association and labor decrease as well with it.

      For a car now you have more power in the same size battery which yields you a more powerful car or a smaller battery with the same amount power which yields you a lighter car; extrapolate after that yourself.

      1HP = 0.735kW =735 Watts and to give you a sense what that is 700 Watts is your fridge or 1400 watts is something that you have in your house that requires a twist lock plug such as your dryer maybe.

      In Engineering sense HP is related to WORK.

      A car with 4 times the horsepower theoretically can do the same amount of work in 1/4 the time. Time is money as they say. If you have a car that is equipped to handle a higher voltage your car can do more work. The issue has been you can fabricate to ratings of whatever voltages you like but the quality of the source hasn't been there; quality meaning voltage availability, mainly being able to store it.


      You can tie all this together. "Kanode has remarked that vanadium will operate at 5 volts vs 3-3.5 for current batteries."

    • This is a good site for some general info. I'll post the page that shares some of the trade offs with different cathode materials. Note vanadium is not included because it is not yet commercialized.

    • Generally, while it still requires an understanding of internal resistance and the ability of the chemistry to give up electrons at a given rate, the higher the voltage the more power the cell can deliver P=VxI. Obviously for many applications such as mobile electronics and motive applications better pack density is very important.

      Also, the supporting hardware such as electrical connections, pack size and the battery management systems (BMS) gets simpler which brings cost down. Less welds, less circuitry to monitor things like individual cell temp. and voltage etc.

      Of coarse the other characteristics of the chemistry come into play but all things being equal higher voltage is good. One of the key advantages of lithium ion vs Nimh cells.

      Just a VERY simple start in answering your question.

        "Pack density"? Do you mean energy density? Voltage has nothing to do with energy density. Watt hours per kg or per litre are what's important.

    • WOW....Excellent question.

      I had only thought of vanadium as a big battery issue.

      What if this higher voltage does impact cellphone, laptop, power tool batteries? and what about military batteries? could that 50 C thingy be something they can utilize?

      We could be looking at a lottery stock here!

      Where are the battery people to comment on this? I need that info now.

      if this increase voltage impacts those batteries I'm buying all I can!

      If this
