The utility model discloses a lithium battery production system which comprises a mould conveyer belt. The mould conveyer belt is used for conveying split mould devices. The system further comprises a turnplate, a plurality of automatic precision power-weighing systems, a plurality of multi-layer automatic powder-leveling systems, a press-forming system, a demoulding cleaning system and a multi-parameter automatic detection system. The automatic precision power-weighing systems and the multi-layer automatic powder-leveling systems are disposed on the periphery of the turnplate at intervals. The automatic precision power-weighing systems are linked with the multi-layer automatic powder-leveling systems. The multi-layer automatic powder-leveling systems, the press-forming system, the demoulding cleaning system and the multi-parameter automatic detection system are linked in sequence through manipulators, and the turnplate is provided with a plurality of stations. By the use of the lithium battery production system, battery quality is guaranteed, producing efficiency is improved and labor environment is improved.
