Abstract
Disclosed are a method for producing a porous electrode and the porous electrode produced by using the method, a method for producing an electrochemical energy storing device and the electrochemical energy storing device produced by using the method, and a method for producing a combination of the electrochemical energy storing devices and the combination of the electrochemical energy storing devices produced by using the method.
Description
Prepared by porous electrode, electrochemical energy storing device is prepared and chemical energy storage combination of devices body preparation field
This disclosure relates to electrochemical field.Specifically, this disclosure relates to prepare the method for porous electrode and prepared by this method porous electrode, prepare the method and the electrochemical energy storing device that is prepared by this method of electrochemical energy storing device and prepare the method for chemical energy storage combination of devices body and the chemical energy storage combination of devices body prepared by this method.Background
Electrochemical power source has been received as energy storage appliance element and widely used, with the development of China's electrical source of power industry, and the demand to electrochemical power source is increasing, to its performance requirement more and more higher.Ultracapacitor is a kind of new electric charge storage element, compared with general battery, have the advantages that capacity is big, support high current charge-discharge, the cycle life of overlength and environment friendly and pollution-free, quick energy release can be provided, high power requirements are met, therefore ultracapacitor has broad application prospects in fields such as new energy, communications and transportation, industry.It has been applied in the application fields such as wind-power electricity generation, solar power generation, hybrid vehicle, UPS, subway, elevator, robot automation at present.
Conventional ultracapacitor includes metal shell, fuse and the cover plate that one end open and the other end are closed, and the blind end of wherein metal shell, which stretches out, is formed with pole, provided with the outside fuse coated by insulating materials inside metal shell；General to use slot rolling flange and laser welding or ultrasonic welding technique, technique is relative complex, and cost is higher.
In actual use, single ultracapacitor can not meet the demand of height output and high-energy-density equipment, it is necessary to which multiple ultracapacitor monomers are constituted ultracapacitor group by the form of serial or parallel connection.Simultaneously, in order to ensure that ultracapacitor combination can be applied under different occasions, especially used in the state of vibration is applied with, need that the ultracapacitor monomer for constituting assembly is fixed, make it have anti-seismic performance, structural failure is to avoid, the fracture, the fracture of collector welding portion and the fracture of monomer electric connecting sheet such as collector.
In assembled battery, it is exactly the fluctuation between cell to be connected in series the outstanding problem of cell.If, under assembled battery fully charged state, there is the high battery cell of voltage ratio average voltage or the battery cell lower than average voltage, thus causing high-tension battery cell performance degradation in the battery series connection of different capabilities.In addition, in anabolic process, with battery cell
Quantity increases, during heavy-current discharge, and due to battery cell heating, battery pack accumulation of heat causes the adverse consequences such as cell expansion.General introduction
