In this recent century, there is ease into taking our technology as something for granted. After all, technology has opened up our abilities to instantly connect to the other side of the world, instantly retrieve information from the Internet, and instantly listen to digital content if desired. However, while a cell phone, laptop, and iPod has many differences from one another, all of those three devices share one item in common at the very least and that is a Lithium-Ion Battery.
Lithium-Ion Batteries are extremely popular in the technology industry for several reasons. First off, they are much lighter then other batteries because they are made with lightweight lithium (a light and reactive metal) and carbon. Second of all, they give the most power per pound. A Lithium-Ion Battery stores 150 watt-hours per kilogram. Compare that with a Nickel-Metal Hydride Battery which only has 100 watt-hours per kilogram or a Lead-Acid Battery which only has 25 watt-hours per kilogram. There is simply no comparison, the Lithium-Ion Battery has the most watt-hours per kilogram (Howstuffworks, 2009).
Some other reasons for the popularity of Lithium-Ion Batteries is that they hold their charge over a long period of time. A Lithium-Ion Battery loses only 5% of the battery’s charge per month while a Nickel-Metal Hydride Battery loses 20% of the battery’s charge per month. Finally, Lithium-Ion Batteries are designed so they can be charged at any time, even if the battery was not at zero percent to begin with (Howstuffworks, 2009).
These reasons are why Lithium-Ion Batteries are some of the most viable options when designing new gadgets. But, the structure of these batteries are why these batteries are being used for new gadgets. A Lithium-Ion Batt...

... that although Apple’s new lithium-ion battery has been heavily improved, the chemistry inside the cell is still the same. There’s still lithium, carbon, and lithium cobalt oxide inside the cell and the lithium still shuttles between the positive and negative electrodes. The chemistry behind the Lithium-Ion Battery is rock solid. Scientists and innovators are merely finding ways to make the lithium move more efficiently or are simply finding ways to add more lithium ions in a cell.
All in all, Lithium-Ion Batteries help power the world to become more efficient and effective. These batteries power up the portable gadgets that the world takes for granted and they help foster communication and education around the world. While every portable gadget might be different in every way, one thing will always be the same among those gadgets and that is the Lithium-Ion Battery.
Table 3.2, located below, shows the battery pack characterization. The table shows the voltage of the battery and the current through the battery as a function of time.
Smartphone's are unquestionably one of the most useful devices of the 21st century but they continue to have one critical flaw- battery life. unpredictable battery lifetime issue from multitasking can have a significant negative effect on the availability of Smartphone devices.
Energy storage is a means of storing energy for future use and can be accessed when needed. Storage can also make the power more solid or resilient so that it can be managed easier. According to Lockheed Martin “The GridStar Lithium-ion system can help customers reduce electric bills, help utilities defer costly transmission and distribution infrastructure upgrades, and enable the integration of behind-the-meter customer renewable electricity production” (Corporation,
Kranzler, J. H., Flores, C. G., & Coady, M. (2010). Examination of the Cross-Battery Approach
This paper is a discussion of the role played by the ideals of the Enlightenment in the invention and assessment of artifacts like the electric battery. The first electric battery was built in 1799 by Alessandro Volta, who was both a natural philosopher and an artisan-like inventor of intriguing machines. I will show that the story of Volta and the battery contains three plots, each characterized by its own pace and logic. One is the story of natural philosophy, a second is the story of artifacts like the battery, and the third is the story of the loose, long-term values used to assess achievement and reward within and outside expert communities. An analysis of the three plots reveals that late eighteenth-century natural philosophers, despite their frequent celebration of 'useful knowledge,' were not fully prepared to accept the philosophical dignity of artifacts stemming from laboratory practice. Their hesitation was the consequence of a hierarchy of ranks and ascribed competence that was well established within the expert community. In order to make artifacts stemming from laboratory practice fully acceptable within the domain of natural philosophy, some important changes had yet to occur. Still, the case overwhelmingly shows that artifacts rightly belong to the long and varied list of items that make up the legacy of the Enlightenment.
In the world today there are hundreds of battery brands and many of them claim to be the best. The question is, is the consumer paying for the named brands worth the extra money. There are two main battery types the alkaline battery and the lithium battery. The alkaline battery is used for everyday uses such as your remote or the new toy you bought your child. The lithium battery is a lighter longer lasting battery used mostly for cameras and high energy using products. In this experiment the alkaline battery is going to be tested. According to two Consumer Reports, Duracell has the best alkaline battery and almost outperforms the energizer lithium batteries. This led the hypothesis for the experiment to say that Duracell will outperform
Batteries where the chemicals cannot be returned to their original form once the energy has been converted (that is, batteries that have been discharged) are called primary cells or voltaic cells. Batteries in which the chemicals can be returned to its original form by passing an electric current through them in the direction opposite that of normal cell operation are called secondary cells, rechargeable cells, storage cells, or accumulators.
Some batteries consists of harmful toxic acids and it may have threats of leakage because of its liquid state. This is called gr...
Each scientist or team of scientists had so much trouble reducing the Lithium compounds because Lithium does not exist in its elemental form in nature. It combines very easily with other elements. Lithium is a soft silvery-white lustrous metal, which can be easily cut with a knife, and it is the lightest of all known metals. It is highly reactive with water and air, and tarnishes readily when exposed to the latter due to a formation of a layer of Lithium suboxide on its surface. Because of its high rate of reaction to air, it must be stored under liquid paraffin, oil, or kerosene, which contain no air, to prevent oxidation. Lithium is detected in its compounds by the characteristic red coloration that it imparts to flames when burned, as Gmelin detected, and by spectroscopic methods.
There are many techniques of battery modelling are present. Few of them are mentioned here with their merits and demerits are given below:
In todays fast-paced society there has been an increased demand for resources to be more accessible. This demand has created the trend of devices, such as laptops, to become more and more portable. A good example of portability would be the way the way desktops evolved into bulky laptops, and then laptops into smartphones and tablets. What makes the MacBook Air more portable than most is it’s small design, long battery life, and with it being lightweight. Other laptops by Apple, like the Macbook Pro, weighing about 5 pounds don’t come close to being as lightweight as the Air. When MacBook Air was released in 2008 it was introduced as the world’s thinnest laptop coming in at 0.68 inches and weighing only 2.38 pounds. Compared to other laptops the only other device that comes close would be ...
The laptop and cell phone are two pieces of technology used worldwide that offer a variety of employments. Along with communication, these two similar devices share many of the same qualities such as gaming, conducting research, and easy accessibility; nonetheless, they do not share all similar qualities.
With Apple continuously innovating they have improved the battery life, increased the memory capacity, or a better colour options. With each change they have considered the value and to what it will mean to the customer and how will that meet their needs.

Today in modern life, humans make use of many objects that have certain devices that they are not even aware of how they work or what their main function is. One of these devices that is used a lot without knowing their existence is what is called a "capacitor." Many people have heard the word capacitor, but also many do not even have an idea of what it means or what is the use for it. In this research, I will concentrate on explaining the physics of a capacitor and describing the main types of capacitors that exist today.
