Abstract: this application relates to a polyolefin-based film, including polyolefins with different weight-average molecular weights; where thickness of the polyolefin-based film is ≤6 �m, and the polyolefin-based film has a machine-direction shrinkage of ≤2% and a transverse-direction shrinkage of ≤1% at 115� c./1 h. this application uses polyolefins with different weight-average molecular weights as raw materials, enabling the resulting polyolefin-based films to have an ultra-thin thickness and a low thermal shrinkage. the reduction in thickness of the polyethylene-based film can improve the energy density of the cell to some extent, and the reduction in thermal shrinkage can improve the short-circuit test pass rate of the bare cell, enhancing the safety performance of the cell. in addition, the reduction in thermal shrinkage helps improve the heat resistance of the polyolefin-based film, delaying the thermal failure of adjacent cells when thermal runaway occurs in a cell.
