Abstract:
A solid-state polymer lithium battery pack and a preparation method therefor are provided. The lithium battery pack includes: single batteries ( 1 ), connecting sleeve members ( 2 ), electric cables ( 3 ), a battery box ( 4 ) and a pouring sealant, and has functions of power supply, power storage and multiple charging/discharging. The preparation method includes: connecting a plurality of single batteries in series by means of connecting sleeve members ( 2 ) to form combined batteries; connecting a plurality of combined batteries in series to form a lithium battery pack; and finally, assembling the lithium battery pack into a battery box ( 4 ), filling a pouring sealant inside the battery box by means of a sealant pouring process for fixing the single batteries ( 1 ) and internal electric cables ( 3 ), and discharging air in the battery box ( 4 ), so that a final solid-state polymer lithium battery pack is obtained.

Claim (Index 7):
A method for preparing a solid-state polymer lithium battery pack, comprising steps of:\n step (1) selecting single batteries comprising: performing single battery cycle test on multiple single batteries to remove unqualified single batteries to obtain qualified single batteries; step (2) matching the single batteries ( 1 ): for the qualified single batteries selected in the step (1), setting index matching requirements between the single batteries, matching to obtain a plurality of single battery assembles capable of meeting the index matching requirements, wherein each the single battery assembles contains required numbers of the single batteries; step (3) cleaning components: the connection straps ( 8 ), the insulating spacer ( 9 ), the fastener ( 10 ) and protective ring are cleaned by an ultrasonic cleaner, followed by washing with water, deionized water and absolute ethanol, and then airing on a filter paper; step (4) treating the battery box ( 4 ) which comprises a battery box bottom ( 4 - 1 ) and a battery box cover ( 4 - 2 ) comprising steps of: after wiping an inside of the battery box ( 4 ) with absolute ethanol, adhering the conductive copper foil to the internal side wall surface of the battery box bottom ( 4 - 1 ), and then installing the protective coil on a corresponding slot position of the battery box bottom ( 4 - 1 ), and curing for 24 hours at a room temperature; then pouring a certain amount of bottom sealant into the battery box bottom ( 4 - 1 ) and the battery box cover ( 4 - 2 ), and then putting into a vacuum box, evacuating to a pressure of not less than \u22120.09 MPa, for a time of not less than 15 min, repeating evacuating for 2 or 3 times until no bubble is within the sealant; finally, putting an insulating strip into the battery box bottom ( 4 - 1 ) and the battery cover ( 4 - 2 ), allowing pouring sealant to completely cover the insulating strip, and fixing the insulating strip with a fixture to make the pouring sealant naturally flow; then, heating and curing the battery box bottom ( 4 - 1 ) and the battery box cover ( 4 - 2 ) with the sealant filled wherein a temperature is control at a range of 60\u00b0 C.\u00b15\u00b0 C., heating time is 6 hours; then cooling naturally; step (5) preparing lithium battery pack ( 7 ): for the single battery assembles matched in step (2), coating a protective film a surface of each single battery in the single battery assemble; punching on a preset position on a positive tab and a negative tab of each of the single battery with a punch fixture; then processing wire cutting, stripping and tinning on installing wires, and processing baking treatment on the connection straps ( 8 ); after the processing, welding the connection straps ( 8 ) and mounting wires, and finally, installing the connection straps ( 8 ), the insulating spacer ( 9 ) and the fastener ( 10 ) of the wires by welding, assembling a number of the single batteries into a lithium battery pack ( 7 ); step (6) pouring lithium battery pack step (6.1) preparing multi-component organic silica gel into pouring sealant according to a certain preparation process; step (6.2) pre-pouring the bottom of the battery box, that is: pouring a certain dose of pouring sealant into the bottom the battery box ( 4 - 1 ); afterwards, putting the lithium battery pack ( 7 ) on the battery box bottom pre-poured, bundling wire harness of the lithium battery pack ( 7 ), and fixing cables and the binding line buckle with GD414 glue; then carrying out pre-seal pouring, that is: adding the pouring sealant to the battery box bottom ( 4 - 1 ) until a height of a sealant layer reaches one half of a thickness of an upper battery layer; step (6.3) after placing the battery box bottom ( 4 - 1 ) disposed in the lithium battery pack ( 7 ) into a vacuum box and evaluating until no bubbles are observed in the sealant; step (6.4) then curing adhesive under a room temperature to prepare sealant for use; step (6.5) polishing sealing surfaces of the battery box bottom ( 4 - 1 ) and the battery box cover ( 4 - 2 ), cleaning, coating with sealant, and then covering the battery box cover ( 4 - 2 ) to the battery box bottom ( 4 - 1 ), and positioning and curing with positioning fixture; finally, pouring sealant after sealing comprising: pouring sealant again via an injection hole punched on a side surface of the battery box cover until pouring sealant overflows from observation holes and vent holes, curing to complete sealant pouring; step (7) testing lithium battery pack: testing performance of the lithium battery pack obtained in step (6) under a room temperature to confirm that the lithium battery pack meets requirements.
