low resistance supercapacitor

Abstract

According to an aspect of the present invention, a low-resistance supercapacitor capable of realizing low resistance comprises a bare cell, and the bare cell is provided with: a first electrode (210), which has a first electrode plate (212) and is connected to the first electrode plate (212). A plurality of first electrode lead taps (214) connected to an electrode plate (212); a second electrode (220), which has a second electrode plate (222) and multiple electrodes connected to the second electrode plate (222) A second electrode lead tap (224), based on the formula 0.8≤(W*Q LT ) / L≤1, determine the length of the first electrode plate (212) and the second electrode plate (222), the number of the first electrode lead taps (214) and the second electrode lead taps (224) , and the interval between the first electrode lead tap (214) and the second electrode lead tap (224), in the formula, W is the first electrode lead tap (214) or the second electrode lead Spacing between taps (224), Q LT is the number of the first electrode lead taps (214) or the second electrode lead taps (224), L is the length of the first electrode plate (212) or the second electrode plate (222).

Description

technical field [0001] The present invention relates to an energy storage device, and more particularly, to an ultracapacitor. Background technique [0002] Ultracapacitor (Ultra Capacitor), also known as Super Capacitor (Super Capacitor), as an energy storage device with intermediate characteristics between electrolytic capacitors and secondary batteries, has the characteristics of high efficiency and semi-permanent life. Shortcomings of short-cycle and instantaneous high-voltage problems of energy storage devices are forming the market. [0003] Supercapacitors have the characteristics of rapid charge and discharge, so they are not only used as auxiliary power sources for mobile devices such as mobile phones, tablet PCs, and notebook computers, but also for electric vehicles or hybrid vehicles that require high capacity, power supply units for solar cells, Main power supply or auxiliary power supply of an uninterruptible power supply (Uninterruptible Power Supply: UPS) or...

AI Technical Summary

Problems solved by technology

[0008] However, for the supercapacitor 100 of the prior art, the relationship between the spacing of the lead taps relative to the length of the electrode plate and the number of the lead taps is not taken into account, and therefore, there is a problem of making the resistance low because it is difficult to achieve low resistance. additional questions

[0009] In order to solve the above problem, although it is conceivable to increase the number of anode lead taps 112 and cathode lead taps 114 to ensure the current flow path, if only simply increasing the number of anode lead taps 112 and cathode lead taps 114 If the number is low, mutual interference between the lead taps 112, 114 will occur, so that there is a problem that the resistance characteristics cannot be improved.
