The invention discloses a lithium battery raw material bag opening device. The lithium battery raw material bag opening device comprises a material barrel, an outer bag clamping part and a cross-shaped bag opening part, wherein the cross-shaped bag opening part comprises a first cutter mechanism and a second cutter mechanism, and a 90-degree included angle is formed between the second cutter mechanism and the first cutter mechanism, so that a cross-shaped notch is formed after the first cutter mechanism and the second cutter mechanism move. The invention further discloses a lithium battery rawmaterial feeding station. The feeding station sequentially comprises a material dropping device, a material shaking device, the bag opening device and a discharging device from top to bottom. The lithium battery raw material bag opening device has the advantages that the structure is simple, bag opening is thorough, cross-shaped openings are formed, so that materials in ton bags are flowed out ina pouring mode and the material discharging direction is perpendicular, discharging is rapid, and the material dropping speed is high; and the feeding station with the bag opening device is high in processing efficiency, and feeding is stable and reliable.
