Abstract

The present invention discloses a flexible battery and a flexible battery pack having the flexible battery. The flexible battery comprises: a flexible circuit substrate; an electric core unit, wherein the electric core unit comprises a positive electrode current collector circuit and a negative electrode current collector circuit, and the positive electrode current collector circuit and the negative electrode current collector circuit are arranged on the same surface of the flexible circuit substrate at the interval; a positive electrode dressing layer and a negative electrode dressing layer, wherein the positive electrode dressing layer and the negative electrode dressing layer are respectively arranged on the positive electrode current collector circuit and the negative electrode current collector circuit; an electrolyte, wherein the electrolyte is arranged on the flexible circuit substrate and is connected to the positive electrode dressing layer and the negative electrode dressing layer; and an external package film, wherein the external package film covers the electric core unit. According to the flexible battery of the embodiment of the present invention, the electric core unit is arranged on the flexible circuit substrate to enhance the flexibility of the flexible battery, and the shape can be adjusted through the appropriate deforming or folding so as to substantially improve the adaptability.

Description

technical field [0001] The present invention relates to the technical field of batteries, and more particularly, to a flexible battery and a flexible battery pack having the same. Background technique [0002] A non-aqueous electrolyte battery that performs charge and discharge by using lithium ions to move between a negative electrode and a positive electrode has been widely researched and developed as a high energy density battery. Lithium-ion batteries using lithium transition metal complexes as positive electrode active materials and carbon or lithium titanate or tin alloy materials as negative electrode active materials have been commercialized. [0003] This type of battery generally consists of a positive electrode, a negative electrode, an electrolyte, and a separator. The positive and negative electrodes are generally prepared as pole pieces, and the positive and negative electrodes are separated by a separator to ensure internal insulation, and the injection of el...
