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.

- Lithium-ion batteries have been replacing older styles of batteries over the past years, and as environmentalist push away from oil these batteries will be further developed. In this paper I will be discussing what the major qualities that are looked for in lithium-ion batteries and how the qualities are obtained. Then, we’ll move on to talk about the problems that arrive with these batteries, and how they can be semi-controlled and monitored. Finally, we will discuss where the lithium-ion battery technology is going.... [tags: bms, environment, capacity]

- History of Lithium-Ion Batteries Rechargeable battery evolution accelerated as the world transitioned to instruments enabled by silicon microchip technology from those of bulky electrical components. Mobile devices were designed to be powered by lightweight energy storage systems. The development of batteries for this rapidly evolving market was challenging: • The nickel cadmium battery had been the only option for modern electronics for many years. It was a great improvement over carbon batteries.... [tags: Battery History]

- Common Types of Batteries LAB (Lead Acid Battery) History The lead acid battery was first discovered and invented by a French physicist called Gaston Plante in 1859. The lead acid battery was the first type of battery that was rechargeable. Source Used: http://lead-acid.com/lead-acid-battery-history.shtml Plante first model for the rechargeable lead acid battery consisted of two lead sheets that have been rolled up and separated by a flannel. This is then placed in to a dilute (10%) sulphuric acid solution.... [tags: Rechargeable battery, Lithium-ion battery]

- Introduction When Luigi Galvani, the Italian physician, touched the exposed nerve tissue in a pair of frog legs they twitched. He unwittingly started the world down the pathway of portable electricity. We have progressed greatly since that day in the mid 18th century. With the help of many scientists we have developed many different types of cells/batteries. The battery industry is a $46 billion industry with over 100 different types of cells. As the energy density rises at a rate of 5% per year, the demand of battery is growing rapidly.... [tags: chemistry, cost, practicality, impact]

- There are factors that represent as a challenge to have high performance Li-Air Battery as shown above. The following will discuss the primary limiting factors of lithium-oxygen battery. Overpotentials Overpotential problem occur on lithium-oxygen batteries because the charging and discharging potentials deviate from standard potential. The overpotentials are the extra energy required to drive the reactions at a specific current density. Then, capacity of the battery is dependent on the clogging of reduction products in the porous cathode.... [tags: high performing Li-Air batteries]

- Lithium Ion Battery: The New “Oil” for Transportation Energy Source The global warming and its effects, which increase the average worldwide temperature, have been discussed by environmentalists extensively over the past few years. They believe that transportation systems, which have been built on an over-reliance of cheap oil, are known to be major causes of global warming. Over ninety percent of transportation medias, such as cars, trucks, ships, and airplanes, have internal combustion engines that are fueled by gasoline or diesel.... [tags: Energy ]

- Introduction The battery architecture for our project had to be carefully considered and chosen. Three types of rechargeable batteries were looked at: Nickel-Metal hydride (NiMH), Nickel Cadmium (NiCd) and Lithium-ion (Li-Ion). Each type of battery architecture has advantages and disadvantages which had to be weighed before choosing which type of battery would best suit our project. A comparison table of the three battery types can be seen below. Lead acid batteries were not considered for this project as they are relatively heavy and storage for our system may be a problem if lead acid batteries were used....

- Energy plays a critical role in the society of today, from the lights in your room to the medical equipment in the city hospital, human life depends greatly on energy production. Between the energy crisis of the 70s and the increasing carbon emissions in the air, renewable and alternative energy has seen increasing demand in research. While solar and wind plants are effective, they face challenges in their inability to hold excess power to be evenly distributed when required during maximum and non-maximum peak hours....

- Sung graduate research group at Cornell historically focused on the dynamics of nanoparticle tethered polymers. These nanoparticles are intended for use in lithium ion batteries. However, there was still more study that was needed to fully understand the nanoparticles. Sung hypothesized that the answers were in the structure of the nanoparticle and the interaction with the tethered polymers. Unfortunately, this was not a current area of study for her research group. This meant that her group did not have the expertise or analytical techniques that she would need for this work....

- In 1817, an aging Swedish chemist was pouring over his work on a late afternoon in Stockholm, Sweden. He was analyzing a strange ore named Petalite that had been procured from an island off the coast of Sweden called Utö. The ore Petalite (which is now recognized to be LiAl(Si2O5)2) had been discovered by a Brazilian scientist, José Bonifácio de Andrada e Silva towards the end of the 18th century on a visit to Sweden. This Swedish scientist, Johann August Arfvedson, detected traces of an unknown substance in his sample of Petalite.... [tags: essays research papers]
