Abstract
The invention discloses a PE diaphragm used for a novel energy storage battery. The PE diaphragm is prepared from, by mass, 12 parts of high-density polyethylene, 24 parts of fumed silica, 50 parts of special oil, 1 part of polyethylene color masterbatch and 1 part of antioxidant. Diaphragm production is carried out according to the following steps that 1, the raw materials are weighed according to the proportion and mixed for over 30 minutes, and uniform mixing is ensured; an extruder is used for extruding, a forming machine is used for forming, the thickness is 0.6-0.8 mm, the extruding temperature is 150 DEG C-190 DEG C, and extruding pressure is 5-20 MPa; a formed sheet is fed into an extraction machine, normal hexane or trichloro ethylene is added for carrying out ultrasonic extraction to form a diaphragm with the needed porosity, and normal hexane or trichloro ethylene is recovered by means of air lifting and drying; after detection, packaging is carried out to obtain a final product. The PE diaphragm used for the novel energy storage battery is formed through the special process and formula, and has good corrosion resistance and oxidation resistance.
Description
Technical field
The present invention relates to a kind of PE dividing plate for novel energy storage cell.
Background technology
Dividing plate is important composition parts in storage battery, and between the positive/negative plate that it is placed in storage battery, the quality of dividing plate directly affects discharge capacity and charge and discharge cycles useful life of storage battery.Dividing plate has following functions in storage battery, and one is prevent positive/negative plate from contacting with each other and internal short-circuit of battery occurs; Two is to have certain intensity, bears the variable force caused after pole plate distortion, bending and active material come off; Three is the electrolyte that diaphragm internal can store some, to ensure the requirement of cell reaction.Under prior art, dividing plate is in its manufacture process, and need to add paint to ensure the reaching wetting effect of dividing plate, such dividing plate antioxygenic property has much room for improvement, and production method is loaded down with trivial details, is unfavorable for reducing energy consumption.
Summary of the invention
For above-mentioned technical problem, technical purpose of the present invention is open a kind of PE dividing plate for novel energy storage cell, and it is made by special technique and formula, has good corrosion resistance and non-oxidizability.
Technical scheme of the present invention is as follows:
A kind of PE dividing plate for novel energy storage cell, its raw material comprises according to mass ratio: the high density polyethylene (HDPE) of molecular weight below 300,000 12 parts, aerosil 24 parts, special oil 50 parts, polyethylene color masterbatch 1 part, antioxidant 1 part, carries out barrier film production according to following step:
Step 1: take above-mentioned raw materials in proportion and mix more than 30 minutes, ensure to mix;
Step 2: extruded by extruder, then shaping by forming machine, thickness is at 0.6-0.8mm, and extrusion temperature is at 150-190 degree, and extrusion pressure is 5-20MPa;
Step 3: shaping sheet material is sent into extracter, adds n-hexane or trichloroethylene carries out ultrasonic extraction, thus forms the barrier film of required porosity, through air lift and drying, n-hexane or trichloroethylene is reclaimed;
Step 4: be packaged to be final products after detection.
The invention discloses a kind of PE dividing plate for novel energy storage cell, it is made by special technique and formula, has good corrosion resistance and non-oxidizability.
