摘要： The system for separating battery cell cores includes a cell core holder for receiving and holding a battery cell core. A cutter cuts an outer wrapping layer of the battery cell core to form an open loose end. A first roller rotates the battery cell core and a sheet opener engages the open loose end to unroll a laminate, which includes a cathode layer, an anode layer, and a polymer separator layer sandwiched therebetween. A pair of second rollers receive, grip and selectively drive movement of the laminate. A cathode breaker applies breaking force to the cathode layer to produce broken cathode layer pieces, which are then collected. An anode breaker then grasps and vibrates the laminate to produce broken anode layer pieces, which are also collected. Finally, a polymer separator layer cutter selectively cuts the polymer separator layer to produce cut polymer separator layer pieces, which are collected.
