On February 21st, Beijing Carbon Century Technology Co., Ltd., the earliest company engaged in the research and development of graphene technology, held the product conference of graphene lithium ion No. 5 rechargeable battery, which is the first graphene lithium ion rechargeable battery in China. . Compared with the ordinary No. 5 dry battery and rechargeable battery, this battery has obvious advantages and can be recycled more than 30,000 times. It can be used in the environment of -45 ° C ~ 60 ° C. These properties are beyond the reach of ordinary batteries. Most importantly, the battery is capable of mass production, and the product launch represents officially on the market. (Carbon Century Chairman Yan Liqun introduced the graphene lithium battery released on site) Graphene batteries are present The release of the olefin storage fighter is another major product after the release of the world's first graphene air purifier and the world's first graphene high-end industrial application, “graphene surface wave detection technologyâ€. Since last year, graphene batteries have been stirred up, and most of them have doubts about graphene batteries, and even questioned attitudes. So, is the graphene battery really true? The answer was given at the conference of the olefin storage king. Yan Liqun, chairman of Carbon Century, told reporters that the full name of graphene batteries should be graphene-modified lithium-ion batteries . There are four ways to apply batteries. One is to use them directly in the negative electrode; the other is to use as a conductive additive for the positive electrode. Lithium batteries must be added with conductive additives, originally added conductive carbon black, and now replace carbon black with graphene, relatively low-end," Yan Liqun said. The third is to directly coat the surface of the positive electrode of the lithium battery, because the lithium positive electrode material is a metal oxide, which will lead to oxidation after a long time, and the conductivity is weakened. After the graphene is covered, the problem will be solved, and the microscopic conductivity can be improved, which cannot be compared with the macroscopic Metal conductivity. The fourth is directly used as the skeleton of the electrode material, thereby increasing the strength of the positive electrode material, and at the same time making the graphene become the skeleton of the positive electrode, improving the life of the lithium battery as a whole, improving the microscopic conductivity and the safety performance of the battery, and the fourth is used by the alkyd battery king. Ways. Unicorn storage, energy saving and environmental protection Carbon Century released the world's first graphene lithium-ion rechargeable battery, the storage battery is the standard 5th battery, with a diameter of 14.5mm and a height of 50mm. The No. 5 battery is widely used in many small electrical appliances and digital products, and is a must-have battery for the family. A battery of No. 7 will also be introduced thereafter. Compared with the ordinary No. 5 battery, the storage tank has obvious advantages. The rated voltage of each battery is 1.9V, that is, the discharge platform voltage of the battery is 1.9V, which is 0.2v higher than the 1.5V of the ordinary dry battery, which can bring more powerful power. In addition, compared with the conventionally charged nickel-hydrogen battery, the cycle life is up to 30,000 times under the correct charge and discharge conditions, and the number of times of charging the normally-charged nickel-hydrogen battery is 1000 times. The working temperature is -40 ° C ~ 65 ° C, ordinary nickel-hydrogen battery working environment 0 ° C ~ 40 ° C, ordinary lithium battery working environment is -10 ° C ~ 40 ° C. It is understood that when the battery is outside the working environment temperature, it will cause the battery voltage to be too low. When the battery is not used, the most direct performance is to directly shut down or disable. Yan Liqun introduced that the ordinary dry battery is a zinc-manganese battery, which uses carbon as the positive electrode and zinc can be used as the negative electrode. Ordinary lithium batteries mainly use lithium iron phosphate as the positive electrode and graphite as the negative electrode. The olefin storage king is a graphene-modified lithium titanate negative lithium battery, lithium iron phosphate is used as a positive electrode, and a graphene-coated lithium titanate material is used as a battery negative electrode (the ordinary lithium battery negative electrode is carbon, and the ordinary dry battery negative electrode is zinc plate). ), greatly improving the electronic conductivity and being able to charge quickly. The gas production rate when the graphene-coated lithium titanate reacts with the electrolyte in the battery is greatly reduced, and the high-temperature cycle life of the battery is effectively improved. Graphene makes life better Why choose this kind of civilian battery to develop and produce? Yan Liqun simply answered, for people's needs, can be used immediately. "Our graphene application products are directly available to the market, and mass production," Yan Zhiqun said, science refers to discovery and breakthrough, Technology is to turn to productivity, change people's lives, and contribute to people's happiness. A dream that Carbon Century has always adhered to and practiced is to use graphene to turn scientific discoveries into productivity and truly realize that "science and technology make people's lives better." Carbon Century is a high-tech enterprise specializing in industrial production of graphene and downstream application technology and product development and industrial practice of graphene. It has strong innovation and innovation. At present, the world's first graphene (single-layer carbon atom) tonnage demonstration production line has been built, and graphene photo-pushing technology, graphene engine oil energy-saving improver, graphene-modified activated carbon for supercapacitor , and graphene modification have been successfully developed. Plastics, graphene air purification products and technologies, graphene surface wave detection technology, etc. An Angle Grinder Machine, also known as a side grinder or disc grinder, is a handheld power tool used for grinding (abrasive cutting) and polishing.

Angle Grinders can be powered by an electric motor, petrol engine or compressed air. The motor drives a geared head at a right-angle on which is mounted an abrasive disc or a thinner cut-off disc, either of which can be replaced when worn. Angle grinders typically have an adjustable guard and a side-handle for two-handed operation. Certain angle grinders, depending on their speed range, can be used as sanders, employing a sanding disc with a backing pad or disc. The backing system is typically made of hard plastic, phenolic resin, or medium-hard rubber depending on the amount of flexibility desired.
Angle grinders are standard equipment in metal fabrication shops and on construction sites. They are also common in machine shops, along with die grinders and Bench Grinders.
