Lithium-ion safety concerns (BU5B) |

When Sony introduced the first lithium-ion battery in 1991, they knew of the potential safety risks. A recall of the previously released rechargeable metallic lithium battery was a bleak reminder of the discipline one must exercise when dealing with this high energy-dense battery system.
Pioneering work for the lithium battery began in 1912, but is was not until the early 1970's when the first non-rechargeable lithium batteries became commercially available. Attempts to develop rechargeable lithium batteries followed in the eighties. These early models were based on metallic lithium and offered very high energy density. However, inherent instabilities of lithium metal, especially during charging, put a damper on the development. The cell had the potential of a thermal run-away. The temperature would quickly rise to the melting point of the metallic lithium and cause a violent reaction. A large quantity of rechargeable lithium batteries had to be recalled in 1991 after the pack in a cellular phone released hot gases and inflicted burns to a man's face.

Hartland, WI - Would the riot in the 1980's movie Do the Right Thing ever
have happened if, instead of a boom box blasting on his shoulder, Radio
Raheem had an iPod plugged into his ears? While times, and electro-gadgets,
may have changed, one constant remains: batteries still required.

TAIPEI- Asustek Computer (2357.TW: Quote, Profile, Research), Taiwan's No. 2
PC brand, said on Tuesday a global battery shortage could affect 30 percent
to 40 percent of its shipments in the second quarter. Vice President Kevin
Lin told Reuters the shortage is likely to be short-term and is partly due
to Korean suppliers, but did not know when the issue would be resolved.
He declined to talk more specifically about the potential impact on Asustek.

Daniel Chang, an analyst with Macquarie Securities, said first-quarter

PC makers to other suppliers. Makers of personal computers might be able to
offset the rising cost of batteries with other components like memory whose
prices have been falling.
Dell said the personal computer industry was experiencing a shortage of
