The huge battery recalls from a few years ago showed that a flaw in the battery could have serious consequences for computer makers and consumers. Several batteries short-circuited and caught fire leading to property damage on more than one occasion.

Panasonic has introduced new battery technology that not only offers longer run time for laptops, but promises to be safer too. The new batteries use a standard cell form factor and pack in 3.1Ah per cell compared to the 2.9Ah of current cells.

In addition to the longer run time, the new battery also features an insulating metal oxide layer between the cathode and anode. This insulating layer prevents overheating in the event of a short circuit.
