NOVELTY - A fire suppressant battery system comprises a battery pack; non-conductive fire suppressant liquid in fire suppressant bladder (56) that melts at temperature above battery pack's desired operating condition and has interior surface defining a cavity receiving the liquid and exterior surface where portion of the exterior surface contacts a section of the battery pack; and fire suppressant protective layer positioned onto a portion of the fire bladder's exterior surface that is on the opposite side of the exterior surface that contacts at least a section of the battery pack.    USE - As a fire suppressant battery system (claimed).    ADVANTAGE - The fire suppressant protective layer applies the minimal external pressure applied from the fire suppressant battery system to the battery pack, keeps the fire suppressant bladder as close to the battery pack as possible, so the first suppressant battery system decreases the damage from a fire from the battery pack or the temperature of the battery pack that is at a temperature above the desired operating condition, and contains any shrapnel or other debris from the battery pack. Contrary to the conventional system, the present system maintains desirable electrochemical characteristics and simultaneously suppresses any undesired fires or sparks.    DETAILED DESCRIPTION - A fire suppressant battery system comprises: a battery pack; a non-conductive fire suppressant liquid in a fire suppressant bladder (56) that melts at a temperature above the battery pack's desired operating condition and has an interior surface that defines a cavity that receives the non-conductive fire suppressant liquid and an exterior surface where a portion of the exterior surface contacts at least a section of the battery pack; and a fire suppressant protective layer positioned onto a portion of the fire suppression bladder's exterior surface that is on the opposite side of the exterior surface that contacts at least a section of the battery pack. The fire suppressant bladder has at least a first connecting material (78) that can interconnect to (a1) the fire suppressant bladder having a second connecting material (79) on it, (b1) a second fire suppressant bladder having a second connecting material on it, and/or (c1) a structure having a second connecting material on it and surrounding at least a portion of the battery pack. The fire suppressant bladder has perforations (76) and/or slots. The battery pack is a single battery or batteries; and contains at least one lithium battery, where the single battery is a lithium battery. The battery pack is used to power a load. The load can be in an airplane, an oil rig, a land vehicle, a water vessel, a medical device or any other application that uses an electrochemical cell(s). The fire suppressant bladder contacts at least a portion of the battery pack's top surface (81), side surface(s), and/or bottom surface (83). An INDEPENDENT CLAIM is included for using the fire suppressant battery system involving: positioning the fire suppressant bladder; adjusting the position of the first suppressant bladder contacting the battery pack by positioning a fire suppressant protective layer onto a portion of the fire suppression bladder's exterior surface that is on the opposite side of the exterior surface that contacts at least a section of the battery pack such that the fire suppressant protective layer applies the minimal external pressure applied from the fire suppressant battery system to the battery pack and keeps the fire suppressant bladder as close to the battery pack as possible, so the first suppressant battery system decreases the damage from a fire from the battery pack or the temperature of the battery pack that is at a temperature above the desired operating condition, and contains any shrapnel or other debris from the battery pack.
