Abstract

An electrically conductive adhesive layer includes an adhesive material; a plurality of electrically conductive dendritic first particles dispersed in the adhesive material and having a cumulative 50% particle diameter D50 in a range from about 20 micrometers to about 40 micrometers; and a plurality of electrically conductive substantially planar second particles dispersed in the adhesive material and having a cumulative 50% particle diameter D50 in a range from about 40 micrometers to about 70 micrometers. The adhesive layer has an average thickness in a range from about 15 micrometers to about 35 micrometers, an electrical resistance in a thickness direction of less than about 30 milliohms, and a peel strength of at least 0.1 N/mm from a stainless steel surface after a dwell time of about 20 minutes at 22° C.
