New Safer Laptop Battery from Panasonic

Worry about Laptop battery fire? New design of laptop battery from Panasonic is safer & prevents the rechargeable battery from overheating
Massive amounts of batteries for laptops have been recalled over the last few years for risk of fire. There is a large-scale recall for Dell laptop batteries( and Apple Macbook batteries( in the summer of 2006, followed by Toshiba and Lenovo. Sony manufactured all of the recalled batteries, and in October 2006, the company announced its own large-scale recall. The batteries were recalled due to the risk that the battery would short circuit and lead to a fire. Panasonic has begun mass-producing a lithium-ion battery for laptops that's rather more capacious charge-wise than current offerings.

The new laptop battery design used an insulating metal oxide layer between the cathode and anode which prevents the rechargeable battery from overheating even if a short circuit occurs. Also, the new Panasonic battery is built to the so-called "18650" form-factor, which is the standard size - 65mm in length, 18mm in diameter - for the cylindrical cells laptop power pack makers build into the box-like units notebook users will be familiar with.

In addition to being safer, the new Li-Ion Battery also lasts longer. Panasonic's offering has a capacity of 3.1Ah. Existing 18650 cells typically have a capacity of up to 2.9Ah, so that's a seven per cent increase in charge with no increase in the power cell's physical size.

Bye-bye, boom-boom laptop batteries? There is no word on when the new batteries should hit the market.
