Abstract
The invention provides a flexible packaging film with a photovoltaic characteristic and a secondary battery. The flexible packaging film with the photovoltaic characteristic comprises a photovoltaic thin film layer and a heat sealing layer; the photovoltaic thin film layer comprises N photovoltaic thin film units and an insulating substrate shared by the N photovoltaic thin film units, wherein theinsulating substrate covers the heat sealing layer, and N is greater than or equal to 1. The flexible packaging film with the photovoltaic characteristic not only can be used for effectively packaging a battery cell, but also enables a secondary battery to have a photovoltaic characteristic, so that the portability of a solar energy-secondary battery integrated system is effectively improved; a high-quality secondary battery with a self-charging function can be obtained; and the service life of a direct-current power device is improved.
Description
technical field [0001] The invention relates to a flexible packaging film with photovoltaic properties, in particular to a flexible packaging film with photovoltaic properties and a secondary battery, belonging to the technical field of energy. Background technique [0002] As a sustainable clean energy, solar energy is an ideal renewable energy. Among them, solar photovoltaic characteristics are an important form of solar energy utilization, specifically a form of energy conversion that directly converts the sun's light energy radiation into electrical energy. At this stage, photovoltaic characteristics have been more and more attention and application. [0003] At this stage, using solar cells as the power supply of lithium-ion batteries has become one of the development directions of lithium-ion batteries. For example, the lithium-ion battery, solar battery, LED lamp and other related components are fixed through the external casing to form a complete set of integrated ...
