　　What are the general equipment and instruments in a battery R&D center? Over the past eight years, Shenzhen Haopeng Technology Co., Ltd. has always focused on product research and development. The company invests 5% of sales every year in the construction of R&D centers, the development of new products and the introduction of advanced equipment. . The R&D center has now introduced a series of advanced instruments to support the development of new products, such as:

　　(1) X-ray diffractometer (XRD) X-ray diffractometer uses the principle of diffraction to measure polycrystalline phases and accurately perform phase analysis (qualitative or quantitative), determination of unit cell parameters, and determination of lattice distortion. , crystallinity determination and Rietveld analysis, etc. The method is simple and flexible, the data is reliable, and it is suitable for various polycrystalline phase analysis. Our company is mainly used for the analysis of the phase and crystal structure of battery materials.

　　(2) Specific surface area analyzer The specific surface area analyzer is a special equipment used to detect the specific surface area of particulate matter. Specific surface area is the surface area per unit mass of substance (㎡/g), which is one of the most important physical properties of powder materials. Our company is mainly used to test the specific surface area of powder main materials and additives, and monitor the quality of incoming powder materials.

　　(3) X-ray fluorescence spectrometer (XRF) X-ray fluorescence spectrometer is an analysis method based on polarization energy dispersion (ED-XRF). It can analyze solid, powder, liquid and other samples, and the analysis range is from Be to U. In recent years, the application scope of X-ray fluorescence spectrometry analysis has been continuously expanded in various industries. Most analytical elements can be analyzed with it, and it has the characteristics of fast analysis speed, wide measurement range, small interference, and non-destruction of samples. Our company is mainly used for the detection of harmful substances in the EU ROHS directive, and rapid analysis of material element components and coating thickness analysis.

　　(4) Gas Chromatograph (GC) Chromatograph (GC) is based on the different distribution coefficients of each component between the mobile phase and the stationary phase. When the sample is brought into the chromatographic column by the carrier gas, it repeats multiple passes between the two phases. In the secondary distribution process, due to the different effects of dissolution, adsorption, permeation or ion exchange of the fixed phase components, the retention capacity is obviously different. After passing through the chromatographic column, they are separated from each other, flow out of the chromatographic column in sequence, and enter the detection The spectrum of each component is displayed on the recorder. Each component can be distinguished based on the sequence, peak height or peak area, and the content of each component can be calculated. Our company uses GC to test the gas composition and content during battery charging and discharging.

　　(5) Laser particle size analyzer The principle of the laser particle size analyzer is that the laser beam encounters the particle sample in the sample cell during propagation and interacts with it. The converged beam scatters to the detector and is converted into an electrical signal for output. It is widely used to test the particle size of various non-metallic powders and metal powders (such as copper powder, alloy powder, rare earth metal powder, etc.). It has the characteristics of good repeatability, wide testing range, and fast testing. Our company is mainly used for powders. Test the particle size of bulk materials to check the quality of powder materials.

　　(6) X-ray fluoroscopy instrument X-ray fluoroscopy instrument uses the penetrating power of X-rays to analyze the internal structure of substances and is widely used to see through bone, non-metallic, thin metal, plastic and other items. Our company is mainly used to observe the internal structure of batteries.

　　(7) Atomic absorption spectrophotometer The atomic absorption spectrophotometer uses the element to be measured to be heated and atomized into ground state atomic vapor, and selectively absorbs the characteristic radiation emitted by the hollow cathode lamp to measure its absorbance. Its absorption intensity is consistent with the test The element content is calculated according to Lambert-Beer's law. It is mainly used for the analysis of trace element impurities and has the two main advantages of high sensitivity and good selectivity. Our company is mainly used for the analysis of trace impurity element content in battery materials and the accurate testing of harmful metal elements in the ROHS directive.

　　(8) Inductively coupled plasma high-frequency optical emission spectrometer (ICp-OES) Inductively coupled high-frequency plasma optical emission spectrometer (ICp-OES) analysis is to excite the sample in a plasma light source, causing the element to be measured to emit radiation of a characteristic wavelength. A method of conducting qualitative and quantitative analysis by measuring its intensity after spectroscopy. ICp-OES has the advantages of fast analysis speed, high sensitivity, good stability, wide linear range, small matrix interference, and can analyze multiple elements simultaneously. Now it is widely used in geology, environmental protection, chemical industry, biology, medicine, food, metallurgy, agriculture and other industries. Our company is mainly used to analyze the element composition and content in battery materials.
