NOVELTY - A lithium polymer battery has an anode flake made by coating and hot extruding an aluminum foil current collector after mixing adhesives with anode powder; a cathode flake made by coating and hot extruding the current collector after mixing the adhesives with cathode powder; and an isolating film made by extracting a high molecule adhesive polyvinylidene fluoride (70-73%), a high molecule coupling agent vinyltrisilane (2-3%), a pore forming agent dibutyl phthalate (3-5%), a plasticizer DBP (Not defined) (0.5-1%), a fire retardant triisocyanate (0.5-1%), and padding silica aerogel (15-17%).    USE - As a lithium polymer battery.    DETAILED DESCRIPTION - A lithium polymer battery comprises an anode flake, a cathode flake, and an isolating film between the anode and cathode flakes. The anode flake is manufactured by coating and hot extruding an aluminum foil current collector after mixing adhesives with anode powder. The cathode flake is manufactured by coating and hot extruding the aluminum foil current collector after mixing the adhesives with cathode powder. The isolating film is manufactured by extracting materials with the following weight ratio: a high molecule adhesive polyvinylidene fluoride (PVDF) (70-73%), a high molecule coupling agent vinyltrisilane (2-3%), a pore forming agent dibutyl phthalate (3-5%), a plasticizer DBP (0.5-1%), a fire retardant triisocyanate (0.5-1%), and padding silica aerogel (15-17%). INDEPENDENT CLAIMS are included for:    (1) a preparation method of the lithium polymer battery, comprising keeping in vacuum under a pressure of not less than 0.8 Pa at 25-45degreesC, a tremor frequency of 30-35 Hz and a time of tremor of 10-15 minutes, and dipping it in a solvent chamber for 30-50 minutes, where the concentration of an extract liquid in the chamber is 90% plus minus 1; keeping in vacuum under a pressure of not less than 0.8 Pa at 25-45degreesC, a tremor frequency of 30-35 Hz and a time of tremor of 10-15 minutes, and dipping it in the solvent chamber for 30-50 minutes, where the concentration of the extract liquid in the chamber is 94% plus minus 1; and keeping in vacuum under a pressure of not less than 0.8 Pa at 25-45degreesC, a tremor frequency of 30-35 Hz and a time of tremor of 10-15 minutes, and dipping it in the solvent chamber for 30-50 minutes, where the concentration of the extract liquid in the chamber is 98% plus minus 1; and    (2) special equipment which can implement the above preparation method, comprising three reaction kettles on the top of a tremor transmission apparatus (20).    The reaction kettle comprises an outside case (12), an inside case (7), a vacuum sealing cover (4), a water-bath heating layer (2), and a solvent compartment (3) having an extractive shelf (6). A water-bath pipe (14) is set up on the water-bath heating layer and is linked outwardly to a water-bath heater (21). A frequency modulation oscillator (19) is set up on the tremor transmission apparatus.
