preparation example Construction

[0025] Correspondingly, on the basis of the above-mentioned positive electrode for a water-injected power generation battery, the embodiment of the present invention also provides the above-mentioned positive electrode preparation method. combined with figure 1 , the method includes the following steps:

[0026] Step S01: dispersing the soluble copper salt in polymer melt and / or solvent to prepare slurry;

[0027] Step S02: Adsorb the slurry on the first water-absorbing material base layer.

[0028] Specifically, the soluble copper salt in step S01 and the first water-absorbing material-based layer in step S02 are as described above in the positive electrode 1 , and will not be repeated here to save space.

[0029]In the above step S01, in one embodiment, when the soluble copper salt is dispersed in the polymer melt, the mass ratio of the soluble copper salt to the polymer is controlled to be (0.5-4):1. By controlling the ratio between the two, a stable slurry can be formed...

Description

technical field [0001] The invention belongs to the technical field of disposable batteries, and in particular relates to a positive electrode for a water-injected power-generating battery and a preparation method thereof, a water-injected power-generating environment-friendly battery containing the positive electrode, and a battery pack containing the water-injecting power-generating environment-friendly battery. Background technique [0002] A battery is an energy storage device that converts chemical energy into electrical energy. It has a wide range of applications in daily life, such as mobile electronics, portable lighting, and electric vehicles. [0003] Batteries are mainly divided into primary batteries and secondary batteries. The primary battery stores a large capacity, but it cannot be reused; the secondary battery can store a relatively small capacity, but it can be recharged and discharged repeatedly. Although secondary batteries occupy the main share of the c...
