Pretty much everyone today has some kind of electronic device, whether it’s an iPod, kindle, laptop, or, most commonly phone. My friend has a Windows phone, and, when she drops it, which is often, the battery sometimes falls out.
The battery, which you can take out of phones, is the key to the phones interior design. There are many different kinds of batteries, like zinc-carbon, alkaline, probably the most well-known, and lead-acid. Lithium-ion batteries are what are usually used in cellphones, as they are rechargeable. A specific combination is lithium cobalt oxide cation and a carbon anode. Zinc-carbon batteries are usually found in the batteries labeled AAA, AA, C, or D. One site writes, “The anode is zinc, the cathode is manganese dioxide, and the electrolyte is ammonium chloride or zinc chloride.” Lead acid batteries are rechargeable, and are usually used in cars. It is often made of lead dioxide and metallic lead, with the electrolyte being a sulfuric acid solution.
Rechargeable batteries are on the rise, especially since they are used in the electronic devices many people use nearly every day. One article states, “Non-rechargeable batteries, or primary cells, and rechargeable batteries, or secondary cells, produce current exactly the same way: through an electrochemical reaction involving an anode, cathode and electrolyte. In a rechargeable battery, however, the reaction is reversible. ” The negative to positive electron energy flow is reversed, and, when the energy is applied to the secondary cell, the cell’s charge is restored.
Cell phones, as most people know, contain radio waves that are transmitted to a tower that can pick up that signal. Radio wave radiation is called electromagnetic radiation. Each phone connects to a base tower. Thousands of base towers around the country can receive signals from around 500m to 30km, based on the surrounding area.
Cellphones use codes, just like computers, to send messages and pictures. The base station is what allows the code to be interrupted and sent to the receiving end. Signals are sent from the base tower to the phone as well, to let your phone know that calls can be made in that area.
Now, this applies no matter what type of phone you have. I myself, and don’t laugh, have a flip phone. Hey, at least you can’t butt dial!
So ta ta for now and I hope to see your chemical reaction soon!
