Transcript of The Battery
Also, the NiCad battery wasn't widely used because the materials used to make it were expensive. Lew Urry worked at the Eveready Battery Company, where he created the small alkaline battery.
Based off the zinc-carbon batteries, it had a longer lasting life and was crucial in the making of battery-dependent objects like cameras and cell phones Energizer's Alkaline Battery Present Day We now have rechargable and powerful, long lasting batteries. Even today, new batteries are being created; batteries that charge in seconds, air fueled batteries, and even bacteria powered batteries. Inside A Battery A battery has a cathode(+), anode(-), and electrolyte. The electrolyte allows the flow of electric charge between the cathode and anode. When the terminals are connected via circuit the electrons go to the cathode. That drive is called the voltage potential, and is expressed in volts. How fast the electrons travel between the two chemicals is called the current, or flow, and is expressed in amps.
In a rechargeable battery, when charging, the electrons go back to the anode, and the process happens again. Thanks for watching
