Chapter 17: Problem 78

Consumer use of rechargeable batteries is growing. Nickel-cadmium batteries, a common type of rechargeable battery, are used in cellular phones, electric shavers, and portable video-game systems. Make a list of the items with which you come into contact that use nickel-cadmium batteries or other rechargeable batteries. Write a short essay about technology that was not and could not have been available before the development of the nickel-cadmium battery.

Short Answer

Expert verified

Nickel-cadmium batteries have facilitated the emergence and improvement of various technologies due to their durability and ability to deliver high currents. Some of the technology might include cellular phones, laptops, cordless power tools, electric cars, and portable gaming systems. These technological developments might not have been possible without the creation of nickel-cadmium batteries.

Step by step solution

Identify Items Using Rechargeable Batteries

Begin by listing all items encountered daily that use rechargeable batteries. These items include, but not limited to, mobile phones, laptops, electric cars, digital cameras, portable gaming systems, electric toothbrushes, and cordless power tools.

Research the Impact of Nickel-Cadmium Batteries

Now, dive into a bit of research to understand the role of nickel-cadmium batteries in these technologies. Look at when these batteries were developed and what technologies emerged or were improved upon as a result. Important points to note include the advantage of these batteries such as their durability, longevity, and the ability to deliver high currents.

Write the Essay

Now that you have the necessary information, begin writing the essay. Discuss the items identified in the first step that utilizes rechargeable batteries, particularly nickel-cadmium batteries. Then, discuss technologies that have benefitted from the development of these batteries. Include in the discussion those technologies that might not have been possible without nickel-cadmium batteries. This might include portable electronics, which rely on the durability and rechargeability of the nickel-cadmium batteries.
