Hey guys, just a few cell questions.Q1. What properties should the metals in dry cells possess?Q2. What problems are associated with Button Cells?Q3. How long can a Lead/Acid battery be used, and what causes it to eventually fail?Q4. What are problems associated with Lead/Acid batteries.Q5. How does a fuel cell vary from a battery?Thankyou in advance.
Q1: They should have plenty of available electrons in easy to strip off shells, they should be cheap and non-toxic and not corrode in the mild acid. They need to have a reversable reaction that can be triggered with electricity (like lead to lead oxide with sulfer) Q2: they are expensive and usually contain Silver which is an environmental hazard. They are also not usually re-chargeable and don't really contain much energy Q3: They usually fail due to repeated stresses on the plates of metal inside which causes short circuts and such. Q4: Poor energy to weight ratio, vunerable to freezing, has toxic (lead) components, can generate Hydrogen gas and explode if abused, corrosive components Q5: a Fuel cell takes a fuel (like hydrogen) and reacts it with something without moving parts and generates electricity as a byproduct (and usually some waste like Co2 or water or something). They are not batteries, rather they are little reactors. Batteries you charge with elecricity, fuel cells you charge with reactants
common disposable alkaline cells are a chemical style, and not many times seen rechargeable. jointly as there are people who say it somewhat is rechargeable, it somewhat is no longer a significant pass attitude because of the fact there are purely some can charge cycles, and the disposable style is possibly to leak and so on. There are additionally authentic rechargeable alkaline cells with somewhat distinctive shape. those are actually not appropriate for deep discharges yet artwork nicely see you later as they're discharged to purely 25% means, that's probable why they have on no account won reliable popularity even with value reward. Rechargeable cells are lead acid, nickel cadmium nickel metallic hydride, and a few styles of lithium cells such because of the fact the lithium ion. those are chemical cells that have a reversible potential. As they discharge the supplies are replaced, yet by way of charging them the supplies are restored. gasoline cells have a gasoline alongside with hydrogen, or maybe a hydrocarbon, organic gasoline, alcohol that's fed on in operations, however the cellular itself is unchanged, so as that they only want gasoline. the unique kinds are a style of opposite of the electrolysis of water into hydrogen and oxygen, the place they use oxygen and hydrogen to produce electric present day and water. Alkaline gasoline cells have been used in the Apollo missions to the moon, and are somewhat hydrogen gasoline cells. The electrolyte makes use of an alkaline answer in water, oftentimes potassium hydroxide, for this reason the call, yet they use hydrogen and oxygen to produce water and electric present day. those are thoroughly distinctive to the alkaline disposable cells all of us comprehend in each and every day existence. call them alkaline gasoline cells.
