Abstract

The invention discloses a linear secure high-energy-density supercapacitor and a preparation method thereof. The method comprises the following steps of 1) respectively taking two conducting fibers which are in core-shell structures as the anode and the cathode of the linear supercapacitor and twisting the two conducting fibers together to form the intertwisted anode and cathode; 2) coating gel electrolyte onto the surface of the anode and cathode and curing the gel electrolyte to form a gel electrolyte layer; 3) connecting the intertwisted anode and cathode coated with the gel electrolyte layer with lead wires respectively through conductive adhesive bonding or tin scolding methods. The preparation method is simple and is low in cost, strong in applicability, and suitable for large-scale industrial production. The produced linear supercapacitor is characterized by lightweight, security, high energy density, good flexibility, intertwining capability, and the like. The produced linear supercapacitor is applicable to flexible energy storage devices, lightweight portable electronic devices, military-use electronic clothes, and other fields.

Description

technical field

[0001] The invention relates to a supercapacitor and a preparation method thereof, in particular to a linear safe high energy density supercapacitor and a preparation method thereof. Background technique

[0002] Supercapacitors have high power density, fast charging and discharging speed, long service life, wide operating temperature range, excellent low temperature performance, and no pollution to the environment. They can be widely used in mobile phones, cameras, pulsed lasers, electric vehicles and other fields. . As a new type of capacitor, linear capacitors have the advantages of small size, good flexibility, and weaving, etc., which also arouse people's widespread interest, and are very likely to be used in wearable electronic devices. Due to its small size, linear capacitors are prone to short-circuiting of electrodes during preparation and use. Therefore, how to prepare a very safe supercapacitor that can avoid electrode short circuit is an urgent ...
