International Classification:

H01M 202

US Classification:

429163

Abstract:

A battery system includes a battery cell having a cylindrical battery cell housing and a housing support external to the battery cell housing. The housing support is formed of an electrical insulator layer contacting the cylindrical external surface of the battery cell housing, and a heat conductor formed of heat-conducting fibers overlying and contacting the electrical insulator layer and aligned generally parallel to the cylindrical axis of the battery cell housing. The heat-conducting fibers are made of high-thermal-conductivity graphite and have a sink end. A fiber-reinforced composite structural support layer is applied overlying the heat-conducting fibers to force the electrical insulator layer into contact with the battery cell housing without the presence of an adhesive between the electrical insulator and the battery cell housing. A thermal sink is in thermal contact with the sink ends of the plurality of heat-conducting fibers at a first end of the cylindrical battery cell housing. A structural base joined to the structural support layer is positioned at a second end of the cylindrical battery cell housing.

International Classification:

H01M 200

US Classification:

429163

Abstract:

A battery system includes a battery cell having a battery cell housing, and a housing support external to the battery cell housing. The housing support is formed of at least two split shell segments. Each split shell segment includes a heat conductor inner layer having a plurality of heat-conducting fibers with heat sink ends, and a structural support outer layer overlying the heat conductor inner layer. The structural support layer is made of a fiber-reinforced composite material. A layer of a structural adhesive bonds the respective heat conductor inner layer of each split shell segment to the battery cell housing. A thermal sink is in thermal contact with the sink ends of the plurality of heat-conducting fibers of each of the split shell segments, and the structural support outer layer of each split shell segment is joined to a structural base. Preferably, a number of the battery cells and overlying housing supports extend between a single thermal sink at one end and a single structure base at the other end, forming a battery pack.

International Classification:

H05K 720

US Classification:

361704

Abstract:

A heat sink board structure includes a thermal/structural base having a composite core layer of a mass of graphitized carbon fibers infiltrated with a first resin material matrix. The graphitized carbon fibers of the composite core are substantially unidirectional and oriented parallel to the face of the composite core layer. Transverse reinforcement layers are bonded to the oppositely disposed faces of the composite core layer. Each transverse reinforcement layer is formed of carbon fibers embedded in a resin material matrix, with the carbon fibers lying substantially in a plane of the transverse reinforcement layer and perpendicular to the carbon fibers in the composite layer. Heat generating and heat dissipating components are bonded to the thermal/structural base. Metallic contact strips are bonded to the surfaces of the transverse reinforcement layers.

International Classification:

B29C 6548

US Classification:

156285

Abstract:

A face sheet is bonded to a porous core by contacting adhesive to the porous core at the bonding face, placing a screen stripping sheet overlying the adhesive, and pressing on the stripping sheet while heating the core and adhesive. The adhesive is thereby forced against the exposed portions of the cell walls at the bonding face and into the interstices of the stripping sheet. The excess adhesive not contacting the exposed cell walls is removed by cooling the stripping sheet and adhesive, and peeling the stripping sheet and excess adhesive from the core. A face sheet is bonded to the porous core with the remaining adhesive that adhered to the exposed cell walls.
