SOFT-PACKAGED LITHIUM-ION BATTERY

摘要

A soft-packaged lithium-ion battery includes: a battery cell, a package used for accommodating the battery cell and an electrolyte filled into the package, wherein the bottom and/or top of the battery cell are/is provided with a porous material layer. Compared with conventional art, the disclosure can realize a buffer function between the battery cell and the package by providing a porous material layer at the bottom and/or top of the battery cell, thereby reducing impact of the battery cell on the package and improving the reliability of the battery cell packaging. In addition, since the porous material layer has an excellent absorbent property, thereby increasing the contact area between the electrolyte and the battery cell, and realizing rapid infiltration of electrolyte in the battery cell with high-energy density and big thickness (thickness ≧4 mm).
