Step one, the first colloid layer is covered with the one side painting of bonding part, is applied at least one side of receiving portion and be covered with refractory layer；In structure
The edge of the surrounding of rack-layer one side, which is applied, is covered with the second colloid layer or in the laminated whole surface coating described second of framework
Colloid layer, up-protective layer is coated in skeleton layer another side；
Step 2, the first housing and are packaged in by naked battery core by way of the first colloid layer and the second colloid layer packaging by hot pressing
Between two housings, the lithium ion battery tentatively encapsulated is formed；
Step 3, carries out fluid injection to battery obtained by step 2, and the step of sealed in advance successively, be melted into, encapsulate again, is encapsulated
The lithium ion battery finished.
