How Does Lenovo Laptop Battery Work

Dec 29

Posted by admin in battery info | Comments off

A laptop battery works in much the same way as batteries that go into portable CD players, remote controls, and shower radios. Just like the batteries used in these household items, laptop batteries come in different sizes based upon the size of the laptop. Laptop batteries however, contain within them complex charging circuitry that works together with a laptop’s hardware.

Inside each laptop battery are internal power cells. These power cells are arranged in a series and are parallel to each other. This is done in order to maximize the voltage level for the lenovo battery as a whole. In addition these cells are controlled by a circuit board. The circuit board regulates how the cells work for both the process of discharging and recharging energy. It makes sure that your battery is not overcharged when charging, and it makes sure that each cell drains the same amount so you can have a longer run time.

Inside each battery there are also positive and negative electrodes. In order to power your laptop, a chemical reaction occurs with both the positive and negative electrodes. This reaction flows in a specific way in order to discharge energy. Plugging in your adapter reverses this process in order to recharge your thinkpad t60 battery. The process of reversing the chemical reaction occurs for both positive and negative electrodes. To make both the discharge of energy as well as recharge process work, this process must be exact. If not, then a short-circuit may occur. This process is basically the same whether your battery runs on Lithium Ion (Li-Ion), Nickel Metal Hydride (Ni-MH), or Lithium Polymer (Li-Poly).

This process is then regulated by hardware within your laptop. The hardware in your laptop ensures that the cells are functioning to their capacity. This is what also allows you to check the life left on your thinkpad t60 battery before it needs to be recharged. A battery symbol is typically displayed on the right corner of your task bar. This symbol graphically shows how much energy has been discharged as well as how much is left.

Although a laptop battery is rechargeable, it does have a limited life span. A typical battery usually lasts for about 500-700 charges before it will no longer be capable of recharging, and a replacement is necessary. The amount of charges can vary depending on the main use of your laptop. Some functions require more energy then others. Using functions such as a DVD player or using the brigh test screen setting can drain the battery quicker, thus requiring it to be charged sooner. The more often you need to charge your thinkpad t61 battery, the sooner the battery will be drained of its life span.

Manufacturers will additionally custom tailor their laptop batteries based upon the needs of each laptop model. A few things that impact the appearance of a battery are the overall size and weight of a laptop. After all, a small notebook would be difficult to carry if the battery weighed an additional two pounds. These factors account for their varying sizes. One size does not fit all in the world of laptop manufacturing. Overall functionality is the key.

breakthrough in lenovo battery safety

Dec 16

Posted by admin in battery info | Comments off

Technology to prevent lithium-ion batteries from catching fire or exploding in laptops and mobile phones may be on the market in the first months of next year, according to its inventor at the Industrial Technology Research Institute in Taiwan.

When lithium-ion lenovo batteries develop internal shorts they can quickly heat up to as much as 500 degrees centigrade and catch fire or explode, as found in several high-profile cases in recent years.

The Taiwanese solution, called Stoba, sits between the positive and negative sides of the battery and when the thinkpad t61 battery hits 130 degrees centigrade, the device transforms from a porous material to a film and shuts down the reaction.

“We have introduced a totally new material to the thinkpad t61 battery,” said Alex Pang, the senior researcher on the team.

According to Pang, thinkpad t40 battery makers in Taiwan are testing the technology and have ramped up manufacturing of Stoba-equipped cells to the thousands. They expect to begin shipping in the first quarter of 2010 and manufacturers suggest that Stoba will add only 2% to production costs.

The danger of exploding lithium batteries is so great that last month the US Transportation Department issued a “hazardous materials” notice. “Many persons who ship lithium batteries do not recognize the hazards… fires in aircraft can result in catastrophic events presenting unique challenges not encountered in other transport modes,” the government said.

Waste Heat Could Double Battery Life on Laptops

Dec 7

Posted by admin in battery info | Comments off

If this wasted energy is cleverly harnessed we might double the use of cell phones talk time without plugging them again and again for recharging. The same could be the case with our laptops; we don’t have to recharge lenovo battery frequently and their wear and tear could be reduced too. The overworked and overloaded poor power plants can shell out more power if their wasted heat energy can be utilized.

Hagelstein is of the view that current solid-state devices that utilize excessive heat and convert it into electricity are not very efficient. He is working with his graduate student Dennis Wu as part of his doctoral thesis to find out a practically dependable heat energy converter that doesn’t carry forward its predecessor’s disadvantages. They are gunning for a realistic technology that could come to achieving the theoretical limits for the efficiency of such conversion,lithium-ion batteries,thinkpad t60 battery,thinkpad t61 battery.

Theory postulates that such energy conversion can never go over a precise value called the Carnot Limit. Carnot Limit was established in 19th-century. It is a formula for determining the utmost efficiency that any machine can achieve in converting heat into work. But the fact is in practice we have only achieved about one-tenth of that limit. Hagelstein working in close association with Yan Kucherov carried out experiments by going for a different technology. They have achieved the enviable efficiency as high as 40 percent of the Carnot Limit. Moreover, their statistics exhibit that this new kind of system could ultimately reach as much as 90 percent of that ceiling.

Hagelstein, Wu and others didn’t try to improve upon existing devices. They started afresh without any past baggage. They make use of a very simple system in which power was generated by a single quantum-dot device. That device is a type of semiconductor in which the electrons and holes are very securely restricted in all three dimensions. So they tried to understand all the features of the device. This helped them in understanding better all the aspect of such machine.

Hagelstein says that he doesn’t merely want to convert heat into energy but he wants to achieve this by getting lots of energy in return. He also admits that current technology is available to harness heat power, but with a catch. It is known as high-throughput power to thinkpad t60 battery. It converts heat from a less efficient system and you get more energy. But this is larger and more expensive system. According to Hagelstein “It’s a tradeoff. You either get high efficiency or high throughput.” But the team found that using their new system, it would be possible to get both at once.

Hagelstein and his team studied a recent paper published by MIT professor Gang Chen carefully. They talked about lessening the gaps between hot surface and the conversion device. They suggested this arrangement as very crucial for improving the output. Gang Chen claimed that heat transfer could take place between very closely spaced surfaces at a rate that is orders of magnitude higher than predicted by theory. The new report admits going a step further that heat can not only be transferred, but converted into electricity so that it can be harnessed.

Robert DiMatteo heads a company, MTPV Corp. (for Micron-gap Thermal Photo-Voltaics). DiMatteo is willing to commercialize Hagelstein’s new idea. He is quite hopeful that the technology developed by his company could yield a tenfold improvement in output power over existing photovoltaic devices. He plans to market this technology next year. At the same time Hagelstein’s work would give the required push and an additional tenfold or greater improvement is possible.In onther words,laptop battery will be a stronger power.People will get better thinkpad t60 battery,thinkpad t61 battery,thinkpad x40 battery.

DiMatteo presents his stats and says that worldwide, when we consume fuel or a powerhouse generates electricity nearly 60 percent of all the energy is wasted. This waste is generally in the form of heat. 60% is substantial amount. DiMatteo is now hopeful that this technology could “make it possible to reclaim a significant fraction of that wasted energy.”

Hagelstein is of the opinion, “There’s a gold mine in waste heat, if you could convert it. A lot of heat is generated to go places, and a lot is lost. If you could recover that, your transportation technology is going to work better.”
