Problems solved by technology

[0006] Although the combination of traditional lead-acid batteries and asymmetric supercapacitors can provide low-cost power storage, because there are two materials that cannot be combined with each other, carbon and lead plates, on the negative electrode plate, resulting in the lead-carbon junction of the negative electrode of the battery It is easier to reduce the service efficiency and life of the battery due to the occurrence of electrode junction corrosion and other phenomena

Embodiment Construction

[0036] In order to make the structural features of the present invention and the achieved effects have a further understanding and recognition, preferred embodiments and detailed descriptions are specially used, which are described as follows:

[0037] Please refer to figure 1 , the manufacturing method of the lead-carbon joint disclosed in the present invention comprises steps:

[0038] Step S1: providing a carbon material and a lead material, a first surface of the carbon material is in contact with the lead material, and the structure of the carbon material includes a plurality of oxygen groups connected to carbon;

[0039] Step S2: heating the carbon material and the lead material to a first temperature, so that the oxygen groups partly detach from the carbon of the carbon material, and combine with the lead material, so that part of the lead material forms lead oxide; and

[0040] Step S3: cooling the carbon material and the lead material, the part of the lead material f...

Abstract

The invention discloses a manufacturing method of the lead-carbon bonding, the structure of the lead-carbon electrode slice and the structure of the lead-carbon battery. The carbon material is enabled to be in contact with the lead material. The oxygen radicals of the carbon of the carbon material are separated to oxidize the part of the lead material into lead oxide which can be used as an interface layer to enable the carbon material to be combined with the lead material. The lead oxide interface layer serves as a stable joint surface between the carbon material and the lead material, so that the lead-carbon bonding structure can be used as a lead-carbon electrode slice, and can be further welded by a wire to serve as an electrode slice of the lead-carbon battery.

Description

technical field [0001] The present invention relates to a production method, especially a production method for stably bonding carbon materials and lead materials, and making this lead-carbon joint structure serve as lead-carbon electrode sheets, which can be further welded by wires as lead electrodes. Carbon battery electrodes. Background technique [0002] Electricity storage is a key technology for power management and promoting the widespread use of renewable energy. Generally speaking, electricity storage can be divided into physical and electrochemical methods. Under the demand of both fast charging and discharging and high energy storage capacity, electrochemical batteries have become the preferred choice for microgrid energy storage. [0003] In the field of electrochemical batteries, the booming hybrid lead-carbon battery, that is, the combination of traditional lead-acid batteries and asymmetric supercapacitors, is a possible way to achieve truly economical power ...
