. Our project is over different brands of batteries powering the same flashlight,and seeing how long the batteries last. What is inside of a battery? There are two electrodes in a battery (one on each side). On this website www.livescience.com states,”One electrode, known as the cathode, connects to the positive end of the battery and is where the electrical current leaves (or electrons enter) the battery during discharge, which is when the battery is being used to power something. The other electrode, known as the anode, connects to the negative end of the battery and is where the electrical current enters (or electrons leave) the battery during discharge”. Now between the electrodes is an electrolyte.
An electrolyte is a liquid that contains electrically charged particles or ions. An ion is a atom that with a positive or negative electrical charge due to the atom losing or gaining an electron. Batteries can also be Alkaline batteries or non alkaline batteries. Alkaline batteries are made of potassium hydroxide which makes these batteries a base that can neutralize an acid. Non- Alkaline batteries are made with zinc and ammonium chloride. According to pre How does a battery work? On www.
livescience.com Elizabeth Palermo states,”The stored chemical energy in the battery converts to electrical energy, which travels out of the battery and into the base of the flashlights bulb, causing it to light up. Then, the electric current re-enters the battery, but at the opposite end from where it came out originally”. The difference between alkali and non alkaline batteries. Batteries can also be Alkaline batteries or non alkaline batteries. Alkaline batteries are made of potassium hydroxide which makes these batteries a base that can neutralize an acid. Non- Alkaline batteries are made with zinc and ammonium chloride.
According to previous knowledge alkaline batteries should have a longer battery life because of there longer lasting shelf life, this is cause by the use of potassium oxide. The advantages to having alkaline batteries would be they are a lot easier to recharge and they also do not require as much power during their use whereas a non alkaline battery would take more power. Also according to proven research you shouldn’t have to worry about alkaline batteries going bad because of their age rather than just being used alot. The A in the name of a double A battery means that it is a filament battery. Also a battery is never fully charged.
Batteries are purposely only charge up to approximately middle range to 80 percent of there actual battery capability, this is because a battery is at its least unstable condition when it is fully charged. Also another thing that most people do not realize is that a battery has to be made to exact speculations.
