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 2):
The solid-state polymer lithium battery pack, as recited in  claim 1 , wherein single batteries ( 1 ) have a laminated structure inside, which comprises multiple layers of a separator, a positive pole piece and a negative pole piece; wherein the positive pole piece is formed by synthesizing paste utilizing main active materials, conductive agent and adhesive agent; wherein the main active materials comprise: lithium cobalt oxide (LiCoO 2 ), lithium iron phosphate (LiFePO 4 ) and ternary material (NCA, NCM); the conductive agent comprises: acetylene carbon black, superconducting carbon black and graphite; and the adhesive agent is polyvinylidene difluoride homopolaymer or homopolaymer of polyvinylidene difluoride and fluorine-containing vinyl monomer. The paste is filmed and then double-sided heat-compounded on a perforated aluminum foil for collecting fluid, dried, grinded, laser sliced to prepare a positive pole piece; negative electrode is made of carbon material (graphite) as the main active material and conductive agent (acetylene black, superconducting carbon black), binder (vinylidene fluoride homopolymer or partial Vinyl fluoride and fluorine-containing vinyl monomer copolymer) synthesis of paste, film, double-sided thermal copper foil (current collector), by drying, rolling, laser chip prepared negative; the diaphragm, the main body is made of vinylidene fluoride homopolymer or vinylidene fluoride and fluorine-containing vinyl monomer copolymer; the entire body of the single batteries are in a dry state, energy density of the single batteries  1  is greater than 180 Wh/kg, battery capacity of the single batteries is not less than 10 Ah, and a rated voltage thereof is 4.2V, each of the single batteries is a rectangular structure with a size of 132 mm\u00d787 mm\u00d79 mm and a weight of less than 220 g.
