Batteries today are omnipresent today that they are invisible to us. Running in cars, digital cameras, drones, bulbs, mechanical tools, inverters, ships, trains, airplanes, windmills and even in satellites. The basic science behind the battery is chemical energy converting to electrical energy containing three main components: Anode, Cathode, and Electrolyte. The revolution in the battery over the years are through several stages of chemical combinations and implementations. Starting from Voltaic Pile to Daniell Cell, then from Lead-Acid to Nickel Cadmium battery, further evolving to Alkaline Battery, Nickel-Metal Hydride (NiMH) and then finally to Lithium-ion battery.

Fiber optic cable versus wire transmission differences boil down to the quickness of photons versus the speed of electrons. While fiber optic cables do not travel around at the velocity of light, they are very close- just about 31 percent slower. Here are more benefits.
Would it be that hackers can access business cable with relative ease, because of cable tapping or various other simple methodologies? The only method to penetrate fiber-optic is to cut the fibers physically, that may cause the transmission to disappear. Read More
