Description

【Technical field】

[0001] The invention relates to a storage battery and a preparation method thereof, more specifically to a conductive electrode plate of the storage battery and a preparation method of the conductive electrode plate of the storage battery. 【Background technique】

[0002] With the advancement of science and technology, the application of batteries is becoming more and more extensive, and people have higher and higher requirements for the performance of batteries, such as higher capacity of batteries, fast charging and discharging, etc.

[0003] In order to increase the battery capacity, metal foam materials (such as nickel foam, copper foam, nickel felt, etc.) are generally used as the conductive matrix of the capacity-limiting electrode of the battery. In the production process of these electrodes, in order to make the active material in the pole piece more compact, the pole piece is usually rolled several times to increase the packing density of the active...
