The reporter was informed on February 13 that Germany Jena Battery Co., Ltd. (hereinafter referred to as "Jena Battery") and BASF are cooperating in the production of a battery electrolyte. The battery technology using the electrolyte is particularly suitable for the fixed storage of renewable energy power and helps to maintain the stability of the traditional transmission network. The Jena battery is based on a redox flow battery (RFB) that uses organic materials. It has successfully developed this technology and is the first to be used in commercial areas worldwide. The two organic electrolytes in the battery are located in different electrolytic cell tanks, and they are separated by a membrane to store current. As a partner, BASF will be responsible for providing one of the electrolytes, which uses an amine as a chemical intermediate, and BASF can produce this chemical intermediate product on a large scale. Jena Battery plans to release the first batch of new redox flow batteries to the market in 2020.
Redox flow batteries store electrical energy in compounds. The two reactive species exist in a dissolved state and circulate in two separate current loops. In the galvanic cell structure, the ion exchange of the two energy storage electrolytes is achieved through the separator. In this process, the dissolved substances will undergo oxidation or reduction reactions; the charging process will absorb electrical energy, and the discharging process will release electrical energy. The storage capacity of the redox flow battery depends on the size of the electrolytic cell; the two electrolytic cells are connected to each other and can be expanded. Therefore, this device is suitable as a large-scale fixed energy storage device with a power of not less than 100 kW and an electric power of not less than 400 kWh. Because the device is highly scalable, its output power can be as high as hundreds of megawatts, and its power can reach the level of gigawatt-hours. For renewable energy generation independent of electricity demand, these characteristics have high practical value. The surplus electricity can be temporarily stored and then sent out when necessary. The new redox flow battery does not contain any flammable or explosive substances; its service life is 10 times that of other batteries, and it can be charged more than 10,000 times.
Some of the plastic variety that people will produce large, low price, wide use and wide influence is called standard plastic.Its connotation often changes with the development of time and science and technology.Important standard plastics are polyethylene, polypropylene, polyvinyl chloride, polystyrene and other varieties
standard plastics including polyethylene, polypropylene, polystyrene, PVC, acrylic - butadiene - styrene), poly (methyl benzene acid methyl ester and amino plastics and so on, its production accounted for more than 90% of the whole plastic production, so it is also called the large plastic varieties.
Merits and demerits
Compared with wood, metal, cement, glass and other materials, standard plastics have the following advantages and disadvantages.
Advantages: (1) easy to form, high degree of freedom of design;(2) easy coloring;(3) stronger than metal;(4) lighter weight;(5) easy to modify, easy to obtain required performance;(6) good electrical insulation;(7) good water resistance and no rust;(8) good chemical resistance;(9) production consumes less energy than metal;(10) as long as the waste plastics are treated well, the environmental damage and pollution will be less than other materials.
Disadvantages: (1) poor weatherability, especially in ultraviolet light, aging easily under uv light;(2) generate static electricity;(3) large thermal expansion coefficient and poor dimensional stability;(4) low surface hardness, easy to produce scratches;(5) poor durability and poor environmental stress cracking.
But with the continuous development of blending technology progress, as well as the standard polymer high-performance achievements, some of its insufficient gradually improved, broadens the application field of Standard Plastic, made of plastic in the position in the national economy more and more important.
Standard plastics has excellent performance, variety and versatility.Standard plastics can replace metal materials, cellulose materials and silicate materials with three traditional materials, and as the most powerful competitor of traditional materials.Standard plastics has been widely used in agriculture, light industry, textiles, electronic appliances, machinery, building materials, packaging and transportation and other departments, profoundly influences the whole development and the progress of science and technology, industrial and agricultural production in social development and national economic development, people's material and cultural living standards improve all aspects such as occupies very important position.
The purpose of standard plastics can be covered in the following aspects:
(1) Agriculture: various kinds of agricultural film, sheet materials, holding irrigation pipes, sprinkling irrigation pipes, fishing nets, breeding boxes, floating materials.
(2) industry: due to the electrical insulation of plastics, standard plastics are already used in the electrical industry to make insulating materials and packaging materials.Manufacturing parts and shells in electronic and instrumentation industries;Transmission gears and bearings in the mechanical industry;Chemical industry of various anti-corrosion containers, pipes, slots, tanks, etc.
(3) construction industry: Plastic doors, Windows, ceilings, floor leather, plumbing and pipe fittings, gas pipes and fittings, etc. are made from traditional materials such as wood and metal.
(4) Packaging: Various woven bags, packaging films, composite films, hollow containers, revolving boxes, corrugated boxes, packaging belts, foam plastics, etc.
(5) daily supplies: all kinds of plastic toys, toothbrushes, soap boxes, raincoats, tableware, utensils, slippers, etc.
(6) medical and equipment industry: all kinds of artificial organs, medical use infusion bags, one injection supplies, degradative medical materials.
(7) electric appliance industry: All kinds of office appliances and household appliances insulation, heat preservation, anticorrosive, moisture-proof housing, resistance to the tang, precise military components and so on.
Divisor in the above areas,standard plastics apply more extensive, at present, some standard plastics by modification to expand the application field, in the defense cutting-edge industry, transportation and aviation industry used as structural materials a lot.
