    摘要: The present disclosure provides an electrochemical energy storage device, which comprises a cell, an electrolyte and a package. The electrochemical energy storage device further comprises a binding material positioned between the cell and the package. The binding material comprises an adhesive layer and a covering layer. The adhesive layer is directly or indirectly adhered and positioned on an outer surface of the cell, and a surface of the adhesive layer which is far away from the cell is an adhesive surface; the covering layer is positioned on the adhesive surface of the adhesive layer, the covering layer is dissolved or swollen into the electrolyte in whole or in part so as to expose the adhesive surface of the adhesive layer, therefore the adhesive layer can make the cell adhered with the package. The covering layer is a polar molecule, the polar molecule comprises one or more selected from the group consisting of —F, —CO—NH—, —NH—CO—NH—, and —NH—CO—O—. The electrochemical energy storage device of the present disclosure may not only fixedly connect the cell to the package so as to resolve the problems during the drop test, but also may resolve the problem that the cell is difficult to put into the package because the two surfaces of the binding material are both adhesive, the electrochemical energy storage device also has an excellent cycle performance and an excellent charge-discharge performance under a high rate.

    摘要: An electrochemical energy storage device comprising an electrode assembly, an electrolyte, a packing shell and an adhesive material located between the electrode assembly and the packing shell. The adhesive material comprises an adhesive layer and a protective layer. A surface of the adhesive layer, arranged on an outer surface of the electrode assembly and far away from the cell, or a surface of the adhesive layer, arranged on an inner surface of the packing shell and close to the electrode assembly, are adhesive surfaces. The protective layer is arranged on the adhesive surface of the adhesive layer. The protective layer is non-cohesive at a normal temperature and pressure, after the protective layer is fully or partially dissolved in the electrolyte, the adhesive surface of the adhesive layer is exposed to bond the electrode assembly with the packing shell, and the protective layer contains a substance to bear an electric charge.

    摘要: The present application provides a lithium-ion battery, which comprises: a wound-type cell formed by winding a positive electrode plate, a separator and a negative electrode plate, a width of the separator is greater than widths of the positive electrode plate and the negative electrode plate; an electrolyte; and a packaging film packaging the wound-type cell and accommodating the electrolyte; a wound ending of the wound-type cell is adhered with a single-sided adhesive layer, an adhesive of the single-sided adhesive layer is a flowable curing adhesive, the wound-type cell and the packaging film are adhered together by the curing adhesive which flows and flows out from a periphery of the single-sided adhesive layer. The single-sided adhesive layer can prevent the wound-type cell from loosening or deforming, rupturing of the positive electrode tab and the negative electrode tab and bursting open of a top-seal in the process of dropping or tumbling.
