Embodiment 1

[0056] Lithium-ion rechargeable bezel battery (size 0420100)

[0057]The battery can be installed in the space of the watch strap. Due to the softness of the battery, it can be well integrated with the watch strap and can be bent at will, which not only saves space but also increases the aesthetics, and provides power for the watch.

[0058] Preparation of conductive substrate:

[0059] Using a PE film with a thickness of 10 microns and a porosity of about 55% as the substrate layer of the conductive substrate can make the conductive substrate more flexible. In order to improve the temperature resistance of the substrate layer, the substrate layer is coated with aluminum oxide glue to form a ceramic substrate layer as a whole. The temperature resistance of the substrate layer can reach more than 200 degrees, and the heat shrinkability is good.

[0060] Aluminum paste and copper paste are respectively coated on the substrate layer by printing and coating, the front and back o...

Abstract

The invention provides conductive substrate, an electrode, an energy storing device and a preparation method thereof. The conductive substrate comprises a non-conductive substrate layer and a conductive layer which is arranged on the non-conductive substrate layer; the non-conductive substrate layer is plastic or rubber state polymer film layer or composite polymer film layer with the thickness of 0.1 to 100 micrometer, the porosity being 40% to 60%, good flexibility, has self-supporting property and is high temperature and corrosion resistant; the particle diameter of the conductive layer is a nanoscale conductive material layer; the thickness of the conductive layer is 1 to 300 micrometers. The conductive substrate comprises a flexible non-conductive substrate layer and the conductive layer and a purpose of improving the electrode flexibility is achieved by increasing the substrate flexibility due to covering of the conductive layer on the flexible non-conductive substrate layer.

Description

technical field [0001] The invention belongs to the field of electrical storage devices, and in particular relates to a conductive substrate, an electrode, an energy storage device and a preparation method for the energy storage device. Background technique [0002] The battery is manufactured by winding or laminating the positive electrode, negative electrode, separator, etc. Wherein the positive electrode and the negative electrode are respectively composed of positive electrode active material, negative electrode active material and conductive substrate (collector). In order to develop flexible battery products, it is necessary to improve the flexibility of the internal components of the battery. [0003] Conventional batteries include both inflexible and flexible outer structures with little flexibility. The main reason for the poor flexibility of the battery with a flexible outer structure is the poor flexibility of the positive and negative electrodes inside the batt...
