Dell and Sony Tracing to find the source

To find the battery problem is due to Sony's production of a batch of Laptop Battery lithium batteries caused by defects. According to Sony, said the factory in Japan, the manufacturing process, because of the metal curling in a free swimming cell has left the tiny metal fragments, some of which fragments caused the battery short-circuit and overheating. Sony Electronics spokesman Rick Clancy said that these fragments may in some conditions, an area from the battery to move to another area, resulting in short-circuit, or in rare cases cause a fire.

According to Clancy said that Dell's brand of battery configuration, along with other factors (such as near the heat source and the battery charge voltage), may eventually result in a Dell confirmed several fire incidents. According to Sony said the manufacturer of the battery pack configuration between the different, but the components - similar to a small volume metal PB992A battery - is the same.

Endpoint Technologies Associates analyst Roger Kay put it, "Sony's a nightmare," but he said the recall will not allow manufacturers to abandon the use of lithium batteries. He said: "well-made lithium-ion batteries are very safe, this is a manufacturing problem, not the fault of lithium technology."

Although Apple did not provide when it began to receive problem reports or initiate an investigation of the detailed information, but Katie Cotton, vice president of corporate communication, said, "We found that previous PowerPC-based iBooks and PowerBooks models some of the 398876-001 Sony batteries are not in line with Apple's security and performance standards. "

As in the case with Dell, Apple encountered problems are lithium battery inside the metal particulate pollution. These particles can be separated Unicom battery positive and negative part of the porous separator causing a short circuit, which led to the release of hot gas and may cause liquids, smoke or fire the chemical chain reaction.

In 2004, the U.S. Federal Aviation Administration Zengyin mass transport lithium batteries there is the danger of fire, but to prohibit the 337607-003 transport aircraft storage batteries. However, still allow passengers to carry a laptop computer or cell phone plane. But Forrester analyst Ted Schadler said that if the fire hazard caused by regulatory agencies to prohibit the use of laptop computers on the plane, then the recall may affect the company's notebook sales.

Why is so fragile that the battery

Dell and Apple recalls this incident is not the first time the 337607-001 battery to overheat, nor is it the first computer makers to recall batteries. Although the vendors together in this rapidly that it was not a wide range of industry issues, but that is not the case. Have reason to ask the question: This is some sort of unusual things, or will as more and more battery-powered devices to enter the market to become an industry trend?

Most modern battery-powered equipment manufacturers facing a hard choice. On the one hand, users expect that these devices can run continuously for several hours, they want their laptop to run at least 4-5 hours, much higher than two years ago, an average of 2-3 hours of run time. However, the pace of development of battery technology can not be with the "hardware development curve" to keep pace. In fact, the battery power of an annual increase of only 5% to 10%, far lower than the processor performance an average of 18 to 24 months increased by several times the speed. Users need to be more smaller, lighter equipment, while nearly all Pavilion ZT3000 batteries in portable devices (especially laptops) and the total volume and weight accounted for a large proportion.
