How Do Batteries Work?
Kierra Roberts

11B How Do Batteries Work? Electricity is the flow of electrons through a wire, that is called a circuit. Batteries have three parts to them, an anode, a cathode, and an electrolyte. The cathode and the anode are hooked up to an electrical circuit. The chemical reaction that is happening causes the electrons to build up at the anode. When the circuit is closed the electrons will be able to get to the cathode. When the electrochemical process change the chemicals in the anode and cathode it makes them stop supplying electrons. So that’s why there's a limited amount of power in a battery. When you recharge a battery you change the direction of the flow of electrons using the other power source just like solar panels. You can sit a battery on a shelf for a year and it will still have power. This is because unless the electrons are flowing fom the negative to the positive terminal, the chemical reaction does not take place or it doesn't happen. Batteries convert chemical energy into electricity. When a battery is connected to an electric circuit, a chemical reaction takes place causing the ions to flow through it one way with electrons flowing the other way. There are alot of different types of batteries, but there are two main types: disposable and rechargeable. Primary cells make up the power in disposable batteries, and secondary cells power the rechargeable batteries. What I learned is that when you charge your cellphone you are really just running the battery in

    Lead acid cells were invented in 1859 by the French Physicist Gaston Plante, and are the oldest types of rechargeable batteries. These types of batteries typically weigh at 5kg, but can range from half a kilogram to over 30 kilograms on the consumer market. Though their chemistry means a very low energy-to-weight and energy-to-volume ratio in comparison to other modern batteries, their ability to supply high surge currents means that the cells maintain a large power-to-weight ratio. This makes them highly desirable for use in large appliances such as motor vehicles, which require the high current provided by this type of battery.…

    H+ ions will join together at the cathode (the negative electrode) to produce H Atoms, and the H atoms will join to form molecules of H2 gas. At the positive electrode (the anode), H20 molecules will decompose to replace the H+ ions lost and release O2 gas. The reactions appear below.…

    The electrons move due to voltage of the battery,so the battery causes an electric field which make the electrons experience a force because of that field. The current flow on the opposite direction of the electrons, on the other hand the flow of electrons move toward the positive side of the battery.…

    There are six cells are joined together to make up the one car battery. In the one cell the positive and negative electrodes each have several plates that are joined together in order to maximise the area of contact between electrode and the electrolyte which is done so the cell can deliver a large current.The electrode plates being close together also increases the current that the cell can deliver. With the electrode plates being so close together in a grid for form to increase surface area and is separated by a thin perforated fiberglass film. The heavy use of the plates leads to them buckling with the extreme amounts of heat which eventually leads to it short circuiting through the plastic film thus making it unserviceable.The battery can be recharged if there is an application of external current. The battery is used to provide a large amount of energy when starting a for the car's starter motor. When driving the battery is recharged by using the electrical energy from the cars alternator. By measuring the the density of the electrolyte the state of charge of the battery can be measured. As the battery discharges, the density of the sulfuric acid decreases as it is being reacted and turned into water. If you use a hydrometer on the cell and see that the floats have dropped too low which is indicating that the sulfuric acid density has decreased and so has the charge of the…

    In all of these voltaic cells, copper was present as the cathode, and the anode was either Zn, Sn, Fe, Mg or Pb. The electrode with the most positive reduction potential in its half reaction had acted as the best oxidizing agent, or was the most likely to be reduced. For this experiment, copper was the best oxidizing agent, with a reduction potential of +.337 V. Copper was reduced in every reaction, also proving that it was the strongest oxidizing agent. The electrode with the most positive oxidation potential in its half reaction had reacted as the best reducing agent, or was more likely to be oxidized. The best reducing agent in this experiment was Mg, with a oxidation potential of 2.37 V. This was also proven in the experimental results, the reaction between copper and magnesium had yielded the highest voltage.…

    Since the early 2000’s, wireless coverage has expanded ten-fold across the country. Cell phones wireless capacity is both a good thing and a bad thing. Wireless gives you the ability to travel and maintain a connection. This connection however depends on your surrounding environment. There are many things that affect radio waves and if something is disrupting the signal from your cell phone to the radio tower, a connection will be hard to get. Staying within large metropolitan areas guarantees a good signal due to the overlapping of radio towers. The battery on a cellphone can be considered both a pro and a con as well. Batteries are a form of contained electricity which allows you to provide an electrical charge to the components within your cell phone. Batteries are not permanent though and are susceptible to fatigue and loss of charge. New advancements in battery technology have been making leap forwards in providing longer lasting and smaller batteries.…

    Batteries come in many shapes and sizes. Some are no larger than a pill while others are heavy and huge size, but most batteries have one thing in common. They store chemical energy and change it into electrical energy. The cell is the basic unit producing electricity. A battery has 2 or more cells, but people often use the world battery when talking about a single cell, too, like a dry cell. One of the most popular batteries that have a cell is a dime sized battery which we use for watches. Cells force electrons to flow along conductors.(DK Science 150).…

    Lithium ions move from the anode to the electrolyte and finally to cathode when they are being consumed, and travel reversely when being recharged. Lithium ions also go through an oxidation process which allows them to reduce the time it takes to recharge the battery by 10times. I found this article particularly interesting because the newly developed batteries will greatly affect my life. With these efficient batteries, I do not have to worry about my phone running out of batteries and will be able to use my phone without charging it for a week. After reading the article I was curious if it will ever be possible to develop batteries that do not need charging process at all. As technological growth increases, I believe that it might be possible to develop batteries that allow phones to be powered for years. Another curiosity that rose in my mind was that if we can use batteries that can produce energy by chemical reaction, why do we use petroleum and waste natural resources instead of using battery…
