Abstract
The present invention includes a battery pack or battery having excellent heat dissipation thus increasing the safety of these devices in high power applications. The battery packs and batteries of the invention have a surface with a high true surface area such that the surface roughness (R), defined by the ratio of the true surface area of the surface to the apparent surface area of the surface, is greater than or equal to about 1.2. In addition, the battery packs and batteries of the invention are preferably formed of material having a high emissivity or include high emissivity labels to provide even greater heat dissipation.
