Batteries and Their Importance Essay - 1061 Words

Batteries and Their Importance We use batteries everyday, we use them to start our cars and to listen to our Walkmans. I have a few questions: How do batteries work? What are the different kinds of batteries Batteries and Their Importance We use batteries everyday, we use them to start our cars and to listen to our Walkmans. I have a few questions: How do batteries work? What are the different kinds of batteries? Why do they die? Why do they lose energy when they are not used for a long time? Well I tried my best to find the best answers for these questions and a little more. Battery, also called an electric cell, is a device that converts chemical energy into electricity. All batteries contain an electrolyte, a†¦show more content†¦Another type of primary cell is the mercury cell. This cell uses zinc as the negative electrode, mercury as the positive electrode, and potassium hydroxide as the electrolyte. This cell gives about 1.3 volts of electricity, and is used in hearing aids and watches because the battery can be flattened. Primary cells maintain a positive charge on the positive terminal and a negative charge on the negative terminal, month after month. These charges attract another and sometimes manage to get to each other through the battery it self. When this happens the battery loses some energy. This is why batteries lose energy if not used. It is possible to slow this process down by refrigerating batteries. Dry Cell Battery The storage, or secondary cell, which can be recharged by reversing the chemical reaction, was invented in 1859 by the French physicist Gaston Plante. This invention was very crucial because it would revolutionize cars. Instead of crank starts the lead-acid battery was used. The lead-acid, which Plante invented is still the same basic design today. The battery consists of six cells connected in a series, and is used in automobiles. Its chief advantage is that it can deliver a strong current of electricity (starting an engine), however it runs down quickly. Each cell is made up of a number of positive and negative plates, separated by thin layers of wood, hard rubber, or plastic, called separators. All the positive plates are connectedShow MoreRelatedUsing Glucose Fuel Battery Of Artificial Pacemakers With Longer Battery Life1342 Words   |  6 PagesUsing glucose fuel battery in artificial pacemakers with longer battery life Abstract Battery life is an important performance of artificial pacemakers. Longer even infinity battery life provides much more conveniences and avoid unnecessary risks for pacemaker users. Glucose fuel battery, a new recent research, may possibly replace current lithium battery in pacemakers.

The company also manufactures power walls and battery charging equipment. Tesla is well known for the production of its first sports car Tesla Roadster coupled with two other cars Tesla Model S and the current Tesla Model X. Elon Musk is the face of the company and has driven the company through odds building confidence among its shareholders and customers (Marcovici, 20 13, p 45). TheRead MoreReverse Logistics1277 Words   |  6 Pagesproduct in a timely manner is often not of major importance to the end users and retailers. Therefore, any processes that rely on the availability of cores or supplies will have to be flexible enough to handle variations in supply. In the case of Johnson Automotive, we will focus primarily on instituting processes that will help to the company to create competitive advantage with its reverse logistics operations. Johnson currently supplies paint, batteries, and electronics to a major auto manufacturerRead MoreA Brief Note On Unmanned Aerial Vehicles ( Uavs )1378 Words   |  6 Pagesvehicles (UAVs) increasingly use battery technology coupled with electric motors to supply energy, as opposed to fossil fuel combustion engines (Floreano Wood, 2015). However, general development associated with UAVs sees the simultaneous processes of advancement of UAV-operated tasks in terms of complication and required time and relative stagnation of the battery technology that must be used to power the UAVs in such tasks (Floreano Wood, 2015). The goal of a battery system in general is to maximizeRead MoreDescription Of Electric Bicycle Safety Essay757 Words   |  4 Pagesconsist six separate parts: The Battery, Dynamo as a wind generator, the BLDC motor, controller, charging system and solar panel. Use of simplified Mechanical design and less weighted dry cell batteries to overcome the above problems. Wind-solar combination is used for self charging. Due to that bicycle become smart and speed is increased. Charging time required for battery of this bicycle is less and discharging time is more.
