Abstract
Provided is a cell packaging material having a layered structure of one or more layers, wherein at least one layer includes a flame retardant, a coating layer imparted with flame resistance, or both. In the cell packaging material, a cell itself does not include any flame resistant film or flame retardant. Therefore, it is possible to provide a cell with flame resistance while not increasing the cell volume or not affecting the cell operation.
Claims26
A cell packaging material having a layered structure of one or more layers, wherein at least one layer comprises a flame retardant, a coating layer of flame retardant, or both.
A cell packaging material comprising:
- an outermost layer formed of a synthetic resin;
- a barrier layer formed on the bottom of the outermost layer;
- a melt extrusion resin layer formed on the bottom of the barrier layer;
- and a sealant layer formed on the bottom of the melt extrusion resin layer,
- wherein a flame retardant is incorporated into at least one of the outermost layer, the barrier layer, the melt extrusion resin layer and the sealant layer, a coating layer of flame retardant is formed on at least one of the outermost layer, the barrier layer, the melt extrusion resin layer and the sealant layer, or a flame retardant is incorporated into and a coating layer of flame retardant is formed on at least one of the outermost layer, the barrier layer, the melt extrusion resin layer and the sealant layer.
A cell packaging material comprising:
- an outermost layer formed of a synthetic resin;
- a barrier layer formed on the bottom of the outermost layer;
- a melt extrusion resin layer formed on the bottom of the barrier layer;
- and a sealant layer formed on the bottom of the melt extrusion resin layer,
- wherein a coating layer of flame retardant is formed on the outermost layer, and a flame retardant is incorporated into at least one of the sealant layer and the melt extrusion resin layer.
A method for producing a cell packaging material, comprising incorporating a flame retardant into at least one layer forming the cell packaging material, forming a coating layer of flame retardant on at least one layer forming the cell packaging material, or both.
The cell packaging material according to 2, wherein the flame retardant is at least one selected from the group consisting of halogen-based flame retardants, phosphorus-based flame retardants, melamine-based flame retardants and inorganic flame retardants.
