The invention discloses a method for tearing an old lithium battery with electricity and water, which relates to a method for disassembling a waste lithium battery, which is characterized by comprising steps that a battery pack or a battery cell of the waste lithium ion battery with a shell disassembled is directly treated into fragments with electricity and water without discharge treatment, andthen the fragments enter the next process. The method has the technical effects that discharge treatment is not needed, discharge labor and discharge time can be saved, fire hazards are eliminated, the production capacity is improved, and the treatment cost is reduced, and the technical problems that in the prior art, in the waste lithium ion battery disassembling process, disassembling can be conducted only through discharge, and fire hazards exist are solved. 旧锂电池带电带水的撕裂方法，涉及一种废旧锂电池的拆解方法，其特殊之处在于：先将拆除外壳的废旧锂离子电池的电池包或电芯，无需放电处理，然后带水带电直接处理成碎片，再进入下道工序。本发明具有无需放电处理，能节省放电人工和放电时间，消除火灾隐患，提高生产能力，降低处理成本的技术效果，解决了现有技术在拆解废旧锂离子电池过程中
