PC vendors blame batteries, not notebooks

Following a series of massive notebook PC battery recalls in August, a group of PC vendors met last week to seek safer lithium ion cells, resolving to draft an improved standard for battery manufacturing and quality control by the second quarter of 2007.

About 20 representatives, including people from Dell Inc., Hewlett-Packard Co., Lenovo Group Ltd. and Polycom Inc. met Sept. 13 in San Jose, California, said Kimberly Sterling, a spokeswoman for IPC, an electronics industry group whose full name is the Association Connecting Electronics Industries. Sterling said some additional companies participated, but declined to name them or indicate how many there were.

The companies are trying to allay consumer fears after a handful of batteries in notebook PCs overheated, some bursting into flames and injuring their users. However, their efforts may be hindered by the absence of Sony Electronics Inc. and possibly Apple Computer Inc. as well, since those companies may not abide by the standard without having an opportunity to help draft it. Sony wouldn't commit to following the IPC advice until it collects further information, said Sony spokesman John Dolak.

Sony skipped the meeting because it was never invited, Dolak said. Instead, the company has representatives on similar boards; Sony executive Doug Smith is chairman of the Rechargeable Battery Recycling Corp., a trade and lobbying group sponsored by battery manufacturers.

Apple did not return calls about the meeting, which was run by committee chairman John Grosso, an executive at Dell.

In August, Dell recalled 4.1 million notebook PC batteries, and Apple recalled 1.8 million notebook batteries. Sony made all the faulty batteries and blamed the problem on short circuits caused by a manufacturing flaw that left microscopic shards of metal floating in the lithium ion cell.

Polycom, of Pleasanton, California, attended the meeting because it had recalled 27,700 of its wireless conference phones in February 2006. It is unclear whether Sony manufactured those batteries, too. Sony announced another defect in its batteries on Monday, when Toshiba Corp. offered to exchange 340,000 notebook batteries for fear they could suddenly lose power, shutting down the computer without saving users' work.

Another hurdle for the nascent IPC standard is criticism from some experts that well-designed laptops shouldn't catch fire even if they do have faulty batteries.

If PC vendors had used standard safety precautions in their notebooks, the defective batteries would have merely shut down, not overheated, said Donald Sadoway, a chemistry professor at the Massachusetts Institute of Technology.

"The technology came out in the mid-90s; we know how to build a safe lithium ion battery," he said.

Engineers typically avoid overheating in lithium ion batteries with safety features such as microcircuitry that monitors the charging process, an additive that makes the electrolyte less flammable or a porous polypropylene spacer that melts at high temperatures, automatically shutting down the battery's chemical reaction.

Sadoway pointed out that it is PC manufacturers who typically specify requirements to battery suppliers.
