Flexible battery and manufacturing method thereof

Abstract

The invention discloses a flexible battery and a manufacturing method thereof, comprising a positive electrode sheet, a negative electrode sheet, a separator, an electrolyte and an outer package, wherein the positive electrode sheet and the negative electrode sheet comprise an electrode film and a nano conductive material layer; the electrode film is a composite structure formed by superposing a graphene layer and a doping layer, wherein the doping layer comprises carbon nanotubes and active material particles, the doping layer of the positive electrode sheet is positive electrode active material particles, and the doping layer of the negative electrode sheet is negative electrode active material particles; and the active material particles comprise an active material, a carbon nanotube and a surfactant, and the active material includes a positive electrode active material and a negative active material. The invention adopts special three-side packaging to increase battery energy density and battery flexibility; improves the usage rate of wearable equipment, increases the continuity of the wearable equipment for collecting the health monitoring data of people, and improves the prediction ability of the wearable equipment for the health status of people.

Description

technical field [0001] The invention relates to a flexible battery, in particular to a flexible battery used in wearable devices and a manufacturing method thereof. Background technique [0002] In recent years, wearable devices, especially electronic watches, electronic pedometers, electronic monitors, etc., have greatly improved the convenience of people's lives, and also improved the ability to monitor their own physical conditions, reducing the incidence of diseases . However, the current development of wearable devices is limited by the battery, and the shape of the battery needs to change a lot, otherwise it cannot meet the evolution of the device and the needs of people. [0003] At present, the batteries on the market still have the problem of insufficient battery life. Users need to take off the wearable device frequently in order to charge the battery. The battery and charging technology needs to be broken through, which makes users less sticky to smart wearable d...
