Safety　issues　significantly　influence　the　iterative　application　of　lithium-ion　batteries　(LIBs),　and　they　have　become　a　critical　challenge　that　requires　immediate　resolution.　Herein,　a　new　type　of　self-quenched　battery　with　an　anode　failure　hunter　was　developed　in　which　a　high　flame　retardant　was　utilized　to　react　with　the　Li　x　C6　of　the　anode,　making　it　ineffective　at　a　temperature　range　of　90-120　degrees　C,　avoiding　its　reaction　with　the　oxygen　produced　by　the　cathode　and　blocking　the　occurrence　of　a　large　scale　chain　exothermic　reaction　(O2　+　Li　x　C6).　After　the　anode　failure　hunter　was　assembled　as　a　self-quenched　battery,　the　onset　temperature　of　the　self-quenched　battery　was　increased　by　15.5　degrees　C,　improving　battery　safety　from　the　intrinsic　level.　More　importantly,　the　energy　release　of　the　thermal　runaway　for　the　self-quenched　battery　has　been　reduced　by　123.7　degrees　C,　significantly　improving　the　safety　of　the　battery.　Therefore,　such　work　could　provide　a　new　strategy　to　design　devices　for　solving　the　safety　issue　in　LIBs.
