NOVELTY - Battery cooling and fire protection system, comprises many battery cells, and a case which holds the battery cells and a cooling liquid comprising a fire protection or fire suppression substance, where one of the battery cells comprises an anode, a cathode (20), an electrolyte disposed between anode and the cathode, a protective housing (12) that partially encloses the anode (36), cathode and electrolyte, and a heat spreader element disposed partially inside the protective housing, and the battery cells are partially submerged in the cooling liquid which is in thermal communication with the heat spreader element and transports heat away from the battery cells through the heat spreader element to the cooling liquid. USE - Battery cooling and fire protection system. ADVANTAGE - The battery cooling and fire protection system has ability to suppress fire immediately upon initiation, and enables battery module/pack to operate in a safe mode with reduced or eliminated chance of overheating and without significantly increasing cooling system weight, volume, and complexity. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included a method for cooling and protecting a battery module or pack comprising the battery cells, which involves holding the battery cells and cooling liquid in a case, where the battery cells are partially or fully submerged in the cooling liquid and the cooling liquid remains stationary residing in the case or is circulated in and out of the case to carry battery-generated heat away from the battery cells. DESCRIPTION OF DRAWING(S) - The drawing shows a rectangular battery cell in battery cooling and fire protection system. Protective housing (12) Separator (18) Cathode (20) Tab (24) Anode (36)
