Embodiment

[0041] A kind of manufacture method of electrochemically conductive functional diaphragm, see Figure 1 to Figure 6 shown, including the following steps.

[0042] In the printing step, the intermediate support 1 is made of 25um corroded aluminum foil produced by East Sunshine, and the intermediate support 1 is used as the mold skeleton. The heat-sensitive adhesive is formed on the intermediate support 1 by printing, and the heat-sensitive adhesive formed on the intermediate support is formed. For the set pattern or shape, other parts of the intermediate support are blank parts. The printing method of the intermediate support body 1 is an anilox roller printing method, a rubber roller printing method, a screen printing method, a transfer printing method or a spray printing method.

[0043] In the batching step, the following weight ratios of active substances, auxiliary substances, plasticizers and wetting agents are mixed to form a primary masterbatch,

Abstract

The invention discloses a manufacturing method for an electro-chemical electrical conducting functional membrane. The manufacturing method for the electro-chemical electrical conducting functional membrane includes that processing active substance, auxiliary material, adhesive and lubricant into granular substance suitable for injection molding, heating the granular substance, and performing plate injection molding, hot pressing vulcanization and cold pressing forming to form a coil film; using printing processing for an intermediate supporter, to be specific, printing thermosetting adhesive on the intermediate supporter to form a needed pattern or a special shape; compounding the coil film with the intermediate supporter, performing die cutting, discharging and rolling to form the electro-chemical electrical conducting functional membrane which can be used for the subsequent processing for a battery. The manufacturing method for the electro-chemical electrical conducting functional membrane is simple in technique and easy to implement, the functional membrane meets the high technical requirements, and the production cost is greatly lowered.

Description

technical field [0001] The invention relates to the technical field of electrochemical power supply and electrode sheet in the electrolytic plating process, in particular to a method for manufacturing an electrochemical conductive functional membrane. Background technique [0002] Existing technology, electrochemical power supply from lead-acid battery one hundred years ago to current lithium-ion battery, nickel-hydrogen battery and other products are used in our various fields, playing an important role in people's life, with the development of science and technology The progress of the electrochemical power supply is increasing, and the performance requirements are getting higher and higher. [0003] The most important thing in electrochemical power sources and electric double-layer capacitors is the lamellar structure or film composed of active materials. We use this lamellar structure or film composed of active materials and auxiliary materials as electrochemically condu...
