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(http://www.laptoptraveller.com/battery-dell-laptop-notebook-batteries.ht) and Apple Macbook batteries(http://www.laptoptraveller.com/battery-apple-laptop-notebook-batteries.h) 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.
