Abstract
A composite article for dissipating thermal energy from a secondary battery cell includes a first graphite layer, a second graphite layer spaced away from and arranged parallel to the first graphite layer, and a metal layer sandwiched between and disposed in contact with each of the first graphite layer and the second graphite layer. The composite article has a thermal conductivity of greater than or equal to about 1,200 W/mK and an electrical conductivity of greater than or equal to about 10,000 S/cm. A secondary battery module includes the composite article and a secondary battery cell having a length and an average measurable temperature along the length during operation of the secondary battery module. The composite article is disposed adjacent and in contact with the secondary battery cell to thereby dissipate thermal energy from the secondary battery cell during operation of the secondary battery module.
