Pouch for Secondary Battery and Lithium Secondary Battery Comprising the Same - A simplified explanation of the abstract

This abstract first appeared for US patent application 18545407 titled 'Pouch for Secondary Battery and Lithium Secondary Battery Comprising the Same

The abstract describes a pouch for a secondary battery and a lithium secondary battery that includes the pouch. The pouch consists of a barrier layer, a base material layer on one side of the barrier layer, and a sealant layer on the other side of the barrier layer. The sealant layer comprises a first sealant layer in direct contact with the barrier layer and a second sealant layer on top of the first sealant layer. The sealant layer has a melt flow rate (MFR) of 14.0 g/10 min or less at a temperature of 230°C under a load condition of 2.16 kg.

• The pouch for the secondary battery includes a barrier layer, a base material layer, and a sealant layer.
• The sealant layer consists of a first sealant layer and a second sealant layer.
• The sealant layer has a melt flow rate (MFR) of 14.0 g/10 min or less at 230°C under a load condition of 2.16 kg.
• The pouch is designed to contain a lithium secondary battery.
• The pouch provides a secure and reliable enclosure for the battery.

Original Abstract Submitted

Provided is a pouch for a secondary battery and a lithium secondary battery including the same. The pouch for the secondary battery includes a barrier layer, a base material layer disposed on one surface of the barrier layer, and a sealant layer disposed on the other surface of the barrier layer. The sealant layer includes a first sealant layer disposed on directly in contact with the other surface of the barrier layer, and a second sealant layer disposed on the first sealant layer. The sealant layer has a melt flow rate (MFR) of about 14.0 g/10 min or less, which is measured at a temperature of about 230° C. under a load condition of about 2.16 kg.
