How much more efficient would a battery made from gold be?
Good question. According to geek.com, researchers at UC Irvine discovered using gold nanowire in elctrolyte gel rather than lithium could withstand 200,000 charging cycles and only lose 5% capacity. That is incredible. On the other hand, silver being a better conductor of electricity than gold. According to the http://silverinstitute.com silver oxide batteries which are currently on the market have replaced their lithium counterparts as well as silver zinc batteries. These batteries may be more expensive but most likely would be cheaper than batteries containing gold. Silver is used in most electronics we use today including computers, cell phones,, cameras, toys, hearing aids, watches and plenty more products.Want to learn more about silver and gold visit my blog Gold and Silver Bullion Dealers
Are forklift batteries still the gold standard for off grid solar power storage? If not, what is?
"Are forklift batteries still the gold standard for off grid solar power storage? If not, what is?""Gold standard"?Lots going on here. Electric forklifts traditionally use lead acid traction batteries.First, chemistry: Traditionally lead acid batteries were the automatic choice for renewable projects because used batteries were cheaply available, they had the ability to supply a lot of power and they required no complex battery management hardware/software. While lead-acid batteries are sometimes still used the scrap value of lead has fluctuated wildly in recent years so there just isn't the availability of cheap used batteries that there once was. Lithium-ion batteries are expensive but offer much more energy density, the battery management hardware/software is much cheaper and better than it used to be too. Nickel-Iron batteries are having something of a comeback. These last forever (50+ years is usually stated but plenty are still working 100 years later), they require no charge contool hardware/software, and can take as much abuse as you can throw at them. There are heaps of other chemistries too. But the overriding point is that no chemistry is "better" than another. You have to chose based on your own priorities.Next there is a verity of types of lead acid batteries, typically: Starter, Leisure, Marine, and Traction. The problem is that there is no formal definition of these terms, manufacturers often lie. However in general:Starter batteries the sort of batteries you find in a car, they are useless for renewable projects because they can be damaged any time they are discharged below 80%.Leisure batteries are very similar but can be discharged down to 60%.Marine batteries can be discharged to 40%.Traction batteries can be discharged to 10%.If you have chosen lead acid batteries then traction batteries are the obvious choice, they do contain far more lead than the other batteries though so they are exceptionally heavy which can cause problems with transportation and even the structure of the building holding them.For renewable projects old battery packs sourced from submarines, forklifts, and other sources used to be exceptionally cheap because the cost of disposal was higher than the value of the metal inside. But since the scrap price of the lead increased dramatically they simply aren't the cheap and plentiful supply they once were so they aren't the obvious choice hey once were.
Which battery is better, a 3000mah or a 4800mah?
It depends.You have to look at the voltage output as well on both batteries. Without specifying what output voltage, the numbers are meaningless on their own. Battery capacity is better specified in terms of Whr (or Watt * Hours), and Watt is calculated by multiplying Voltage (Volts) * Current (Amps).Take a real world example - the infamous iPhone “gold” replacement battery commonly found on eBay.Omg omg… it says 2680mAh versus the standard battery’s 1560mAh? It’s got to be better right??? I’ll be more than happy to pay double for it!Except… It’s a scam. Both batteries have roughly the same capacity, per this test result: SOLVED: Gold, high capacity battery? What is that? - iPhone 4So how did they manage to claim this? Well if you look at the fine print on both batteries, they both say “3.8V 5.92Whr. So some scamming genius decided, he can divide 5.92Whr by 2.21 Volts and claim 2680mAh without specifying a voltage next to it.So moral of the story… to specify the capacity of a battery there must be either:A) at least a Whr number on the batteryor, B) a mAh number along with VoltageGood luck, and don’t get scammed!
Could graphene be used to make better computer chips than gold?
The benefit in using gold in computer chips is gold an efficient transmitter of electrical energy and more resistant to corrosion than silver and copper Graphene has the potential for being a superior electrical transmitter as evidenced by its use as terminals in Li ion batteries and is more resistant to corrosion. So yes
Identify this smell (from a Li-Ion battery)?
I'm curious about what substance this is. I smelled it while disassembling a small lithium ion battery. It is a STRONG smell, and due to the amount of odor produced, it is probably an essential component of the battery. I would describe the smell as: sweet, fruity, almond, irish cream. It is similar smelling to the ether formerly used as anesthetic. I think it's likely one of the aldehydes. Any ideas which one?
Suppose it took 108 joules of energy to raise a bar of gold from 25.0°C to 29.7°C. Given that the specific hea?
You can use Q = m*c*change in Temp; Q = heat or energy, m = mass, change in T = temperature, c = specific heat capacity. First, rearrange the equation to m = Q / c * change in T. Substitute and solve. Answer is E) none of the above.
Wich has more atoms, 150.0g of gold or 10.0g of lithium?
Lithium has more atoms. Calculations prove this. Take gold and divide it by its molar mass to get grams to cancel and get moles of gold. 150.0g/197g per mole = .76 mol Au Now take moles and multiply by Avogadro's number for number of atoms (6.02^23) .76 mol Au x 6.02^23 atoms per mol = 4.6^23 atoms Au Now do the same procedure to solve for atoms of Lithium 10.0g/7g per mol = 1.43 mol Li 1.43mol Li x 6.02^23 atoms per mole = 8.6^23 atoms Li So after looking at the calculations you can see that 10.0g of Lithium has more atoms than 150.0g of gold. So number of moles is determined more by the elements molar mass rather than the amount you have.
