The utility model discloses a safety processing device for a high-capacity battery. The safety processing device comprises a battery module and a safety processing device connected with the battery module, an explosion venting opening of the battery module is connected with the safety processing device through a collecting pipe; an alkaline solution for saponification is injected into the safety treatment device. According to the application, the liquid generated after the thermal runaway of the battery is subjected to the saponification reaction, so that potential risk factors caused by the thermal runaway of the battery are reduced or eliminated essentially, the danger of combustion and even explosion of the battery is avoided, and meanwhile, the huge harm of electrolyte discharge to the ecological environment is avoided. 本申请公开了一种大容量电池的安全处理装置，包括电池模组，与所述电池模组连接的安全处理装置；所述电池模组的泄爆口通过汇流管与所述安全处理装置连接；所述安全处理装置内注有进行皂化反应的碱溶液。本申请通过将电池热失控后产生的液体进行皂化反应，从本质上减轻或消除电池热失控所带来的潜在危险因素，电池避免存在燃烧甚至爆炸的危险，同时避免电解液外排对生态环境来说危害巨大。
