ladder-acid onslaught
The type of battery use in cars can be recharged. Consists of several secondary mobile phones connected in series. The Anodes(-ve) ar pencil lead and the Cathodes(+ve) are lead dioxide and electrolyte is Sulphuric acid.

Anode:
Cathode:


During discharge, sulfuric acid is consumed and lead(II) sulphate is precipitated. This causes the electrolyte solution to less dense. The density of the electrolyte solution is a run to the condition of the battery.

During use, the reactants in a lead-acid battery are used up and th battery becomes flat. Recharging is an electrolytic surgical procedure: the battery is connected to an external electricity source so that the direction of electron flow is opposite to that during normal use. The employ electric current causes the reverse electrode reactions occur. The cell reactants are replenished and the battery is restores to a charged condition.

Expensive due to cost of lead, long life, rechargeable, rotund so it is not portable, stores charge in remote locations e.g.solar strength when connected to solar panels, explosive Hydrogen Gas released when charging. They are rechargable and have a pretty long life. However, they have a low energy density.



So they are not adapted for compact portable applications like cell phones or storing a lot of energy, like an electric car.

Environmental impacts of the lead-acid battery allow in the disposal problems of the battery, because Lead is toxic it has to be disposed of properly. The lead-acid cell has a large impact on society because Lead acid cells are used in most (non-electric and non-hybrid) cars. banish impacts include lead poisoning among workers who mine lead and cycle old batteries.

Button cell

The button cell is small and mold like a button. They are used for small devices such as cameras, calculators, electronic watches and hearing aids. They need a very high energy density to compensate for their small size. This is achieved by using highly...If you want to get a full essay, establish it on our website: Ordercustompaper.com
