By contrast, Boston-Power has largely kept the internal chemistry the same and instead fine-tuned the other elements that make up a battery. (Lampe-Onnerud and other members of the Boston-Power executive team have worked in the lithium-ion industry for years.) The can, or outside casing around the battery cells, on the Sonata is made from a metal alloy that is stronger Acer aspire 5100 battery than the iron cans used with conventional notebook batteries and, thus, will remain intact in the case of a thermal reaction or fire, according to the company.Boston-Power also spent a lot of time on the interrupt system, which prompts the battery to shut down permanently if there is danger of a thermal reaction. The company can't guarantee the batteries will never have problems, but it has added safety features not seen in ordinary batteries.In addition, Boston-Power works closely with its contract manufacturers, Lampe-Onnerud said, and has developed a process monitoring system that collects more accurate data about each battery as it goes through manufacturing and assembly. There is a catch, however. The Sonata will sell at a premium. Notebook makers always try to minimize component costs. Manufacturers also tend to be skittish when it comes to trying out products from start-ups. At the same time, the Sonata will outperform conventional batteries, the company said. It will recharge from depleted to 80 percent capacity in about 30 minutes. The Sonata also will provide like-new performance for three years, according to the company. Most notebook batteries begin to degrade after three to six months. Electronic manufacturers should consider what truly is the heart of most of their portable devices - the battery. The size, shape, weight, and function are all directly related to the battery that will power them. The battery also provides an essential backup on printed circuits and computer systems. Acer aspire 5500 battery It seems that just about every six months a new battery technology emerges using much more exotic and expensive materials. Think about what the cell phone has become as a direct result of the size and capacity of the batteries powering them. Each successive improvement makes batteries smaller, able to hold a charge longer, and able to charge faster. This article takes a look at some of the new battery technologies and how they will improve the electronics industry.
Latest Developments.Sanyo introduced the new "eneloop" battery, which is a rechargeable NiMH battery useable right off the shelf. Unlike previous rechargeable batteries, which have limited shelf life because of their rapid discharge, these batteries retain 85% of their charge even after one year. Because this battery can be used for thousands of charges and is easily recycled, it is much more convenient, cost-effective, and eco-friendly than the traditional single-use batteries.Toshiba Corporation has announced a breakthrough in lithium-ion batteries that makes long recharge times a thing of the past. The company's new battery can recharge 80% of a battery's energy capacity in close to one minute, approximately 60 times faster than the typical lithium-ion batteries in wide use today. The battery also has a long life cycle, losing only 1% of capacity after 1,000 cycles of discharging and recharging, and can operate at very low temperatures.Techtronic Industries Co. Ltd. of Hong Kong developed the V28™. This 28-volt battery delivers increased power and up to twice the run time of traditional 18-volt models, yet the battery weighs slightly less. This means the introduction of new tools like the world's first cordless band saw powerful enough for every day professional use. Containing no cadmium, the lithium ion battery has built-in fuel gauge that tells users how much run time is available. In addition, this battery is equipped with built-in Performance Optimizing Circuit to provide consistent, fade-free power throughout discharge cycle to ensure job power consistency.
Boston-Power also has hatched plans to move into making large format lithium-ion batteries that could be used in plug-in hybrid cars. The current Sonata batteries for notebooks are based on small format cells, and each cell provides about 4.4 amp hours of power. Conventional notebook batteries provide about 2.6 amp hours. (Amp hours measure how much power a battery can store.) Plug-in hybrids require batteries with cells that can provide 5 to 10 amp hours. Boston Power, in its labs, has come up with batteries that get into this range, but they are still in the experimental stage. (A battery for a plug-in will also contain far more cells than a typical six- to nine-cell notebook battery.)boston-power."We have solved a fundamental problem for large cells," Lampe-Onnerud said. "We will take the same time to make sure it is Acer batecq60 battery fine-tuned forthe appropriate market."Boston-Power is one of a number of relatively new companies trying to improve the humble battery, particularly the now familiar lithium-ion ones. A favorite of notebook makers and consumer electronics manufacturers, lithium-ion batteries can hold more energy than competing types of batteries.Unfortunately, they also come with a glaring side effect. They can short on occasion, resulting in a "runaway thermal reaction" in industry parlance.
