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 11):
The method for preparing a solid-state polymer lithium battery pack, as recited in  claim 7 , wherein the step (6.2) pre-pouring the battery box bottom with sealant specifically refers to pouring a certain amount of the pouring sealant into the battery box bottom, after leveling placing in a vacuum box to evacuate to a pressure of not less than \u22120.09 MPa holding pressure, an evacuating time of not less than 15 min, allowing repeated vacuum for 2 to 3 times until no bubble is within the pouring sealant;\n in the step (6.2), the glue before sealing specifically refers to: after putting the lithium battery pack ( 7 ) in the battery box bottom, firstly setting up the upper-layer battery by a fixture, slowly adding the pouring sealant to the battery box bottom, controlling a height of the sealant-pouring just over a lower-layer battery until the pouring sealant slowly levels out and covers a surface of the lower-layer battery, and then removing the fixture to fall the upper-layer battery down, continuing to pour the pouring sealant until a height of the pouring sealant reaches a half of a thickness of the upper-layer battery; the step (6.3) specifically refers to: putting the lithium battery pack into a vacuum box, evacuating to \u22120.08 MPa\u00b10.005 MPa holding pressure, an evacuating time is not less than 15 min, allowing repeated vacuum for 2 or 3 times until no bubbles are in the pouring sealant; in the step (6.5), the pouring sealant after sealing specifically comprises steps of: pre-punching an injection hole and a vent hole on a front surface of the battery box cover, covering the battery box with a protective layer; putting the battery box in a sealant pouring tool, wherein the injection hole and the vent hole on the battery box face upward, then slowly inserting an injection pipe into the injection hole, injecting a dose of the pouring sealant prepared into the battery box through the injection pipe by a disposable syringe; and putting the lithium battery pack into a vacuum box, evacuating to a \u22120.065 MPa\u00b10.005 MPa holding pressure for not less than 30 min; then repeating injecting sealant and evacuating until no bubbles overflow and a small amount of the pouring sealant exists in the injection pipe and an exhaust pipe; then taking the lithium battery pack and the sealant pouring tool out of the vacuum box; placing the lithium battery pack at an angle of 45\u00b0 to a ground and curing for not less than 14 days.
