[0094]

[0095] positive electrode material

[0096] Material name actual material Dosage (unit: g) Ratio (mass ratio) Matrix resin Vinyl resin 3 22.7％ positive active material manganese dioxide 3 22.7％ Conductive powder silver powder 6 45.5％ Disperse wetting agent Polymer 0.2 1.5％ Thinner DBE 1 7.6％ total 13.2

[0097] The electrolyte is zinc chloride containing 30% electrolyte; the base layer (the negative base layer 1 and the positive base layer 9) is PET.

[0100]

[0101]

[0102] positive electrode material

[0103] Material name actual material Dosage (unit: g) Ratio (mass ratio) Matrix resin Vinyl resin 3 22.7％ positive active material manganese dioxide 3 22.7％ Conductive powder silver powder 6 45.5％ Disperse wetting agent Polymer 0.2 1.5％ Thinner DBE 1 7.6％ total 13.2

[0104] The electrolyte is zinc chloride containing 30% electrolyte; the base layer (the negative base layer 1 and the positive base layer 9) is PET.

Embodiment 3

[0106] The difference with Example 1 is that the first negative electrode active material of the core-shell structure is not mixed into the coating auxiliary agent, and the negative electrode material in this comparative example 1 is caused by flocculation between the first negative electrode active material and the second negative electrode active material. The negative electrode material is a paste structure as a whole, which cannot be well applied in plate printing, spraying, screen printing, deposition, etc. The negative electrode can be formed by manual brushing.

Abstract

The embodiment of the invention discloses a self-power-generation structure, and relates to the technical field of primary batteries. The self-generating structure is composed of the following structures: a base layer; the electrolyte layer is attached to the surface of the substrate layer; the positive electrode layer and the negative electrode layer are attached to the electrolyte layer and do not make contact with each other. Compared with other structures, the self-power-generation structure in the embodiment of the invention has the advantages that the layer thickness is further reduced, the self-power-generation structure can be realized only through a three-layer structure, the problem that the thickness of the self-power-generation structure is too large is greatly solved, and the self-power-generation structure is more suitable for manufacturing wearable battery elements or battery elements with other flexible requirements.

Description

[0001] The present invention is a divisional application of a patent with the application number 2019107231264, the application date is August 6, 2019, and the invention title is "a self-generating electrode material, a negative electrode, and a self-generating structure". technical field [0002] The invention belongs to the technical field of primary batteries, and in particular relates to a self-generating electrode material, a negative electrode, and a self-generating structure. Background technique [0003] With the continuous development of the global economy and the continuous improvement of people's living standards, energy and environmental issues have become increasingly prominent. Batteries with long cycle life are widely used as energy storage carriers in power, energy storage, consumer electronics and other fields. Among them, lithium-ion batteries, as a representative, have been widely used in many fields such as mobile phones, digital portable products, and el...
