Abstract

The invention, which belongs to the cell technology field, discloses a cylindrical supercapacitor. The supercapacitor comprises a cylindrical hollow housing, an electrode set, an upper current collector, a lower current collector and an upper cover. The top of the cylindrical hollow housing is opened and the bottom is closed. The electrode set is arranged in the housing. The top end surface and the bottom end surface of the electrode set and the upper current collector and the lower current collector are respectively welded together. And the upper cover is sealedly connected with a top edge of the housing and a through hole is arranged in the middle of the upper cover. Besides, the center of the top of the upper current collector is projected upwardly to form an anode column that is extended outwardly from the through hole; and the anode column and the through hole are in interference fit and an outer wall of the extending end of the anode column is provided with threads. And the center of the outer bottom of the housing is provided with a cylinder, wherein the outer wall of the cylinder is provided with threads. According to the invention, the cylindrical supercapacitor has advantages of safe and reasonable design, compact overall structure, and long service life; and the cylindrical supercapacitor is especially suitable for an application occasion on which it is needed to provide rapid energy releasing and a high power demand can be met; therefore, the cylindrical supercapacitor has wide prospects.

Description

technical field

[0001] The invention belongs to the technical field of supercapacitors, in particular to a cylindrical supercapacitor. Background technique

[0002] Supercapacitor, also called electrochemical capacitor, is an emerging charge energy storage device in recent years. It has long life, safety and reliability, and huge energy storage. It is an ideal energy storage device. It has both the high-current fast charge and discharge characteristics of ordinary capacitors and the energy storage characteristics of batteries, filling the gap in specific energy and specific power between ordinary capacitors and batteries. Due to its special advantages, its application fields are very broad, involving various fields such as transportation, wind energy, solar energy, military, and industry.

[0003] At present, supercapacitors mainly include cylindrical capacitors and square capacitors in appearance. Among them, the cylindrical shape can be divided into two types: positive ...
