Abstract
Methods of insulating batteries, and in particular thin-profile batteries comprising button-type batteries and resultant insulated battery constructions are described. In one aspect, a flowable insulating material is distributed over an edge region of a battery and subsequently provided into a generally non-flowable state. In one implementation, the battery is rotated while the flowable material is provided over the edge region. Provision of the flowable material over the edge region can comprise dipping the edge region into a volume of flowable material or dispensing a desired amount of flowable material over the edge region. In another implementation, an insulating jacket is provided over the battery having a minimum thickness of no greater than about 2 mils.
