Interpretation of lithium battery industry

Lithium ion battery was first developed by Sony Corporation in 1990. It is widely used in 3C electronic products, electric tools, new energy vehicles, energy storage and other fields because of its high working voltage, large specific energy, long cycle life, good safety performance, small self discharge, fast charging, wide working temperature and other advantages.

Determination of peroxide in tetrahydrofuran

Tetrahydrofuran and ether are easy to produce peroxide when stored for a long time. Be careful when using. Be sure to detect the peroxide content in the solution first. If more than 0.05% peroxide is present, the peroxide must be removed before distillation. If the peroxide content is 1% or higher, it must be treated by incineration.

The role of NMP in the battery

The most commonly used solvent in the pre-treatment of lithium-ion batteries is NMP, commonly known as methyl, known as N-methylpyrrolidone, and the molecular formula is C5H9NO. The role of NMP in the battery: as a PVDF solvent, participate in the dispersion of the slurry, form a uniform medium, and maintain a stable slurry for a long time in a certain viscosity range.

Composition and function of cyclohexylamine corrosion and scale inhibitor

In industry, cyclohexylamine is prepared by aniline catalytic hydrogenation, and the commonly used catalyst is cobalt. It can also be divided into two methods: atmospheric pressure and pressurization. In the atmospheric method, the molar ratio of aniline to hydrogen is 1:2, the addition reaction temperature is 150~180 ℃, and the pressure in the reactor is atmospheric. In the pressurization method, the molar ratio of aniline to hydrogen is 1:10, the addition reaction temperature is about 240 ℃, and the pressure in the reactor is 14.61MPa. The fixed bed liquid phase hydrogenation method is adopted.

The improvement of NMP helps the rapid development of lithium batteries.

The Chinese name of NMP is N -Methy-Pyrrolidone, is a key chemical solvent and extractant in electronic chemicals. Since the 1990s, NMP has risen in the domestic petrochemical industry. After more than 20 years of development, it has gradually been completely localized by the initial basic import. The scope of application has been gradually limited to the petrochemical, coating, pesticide and other industries. Expanded to use in insulation materials and blending solvents, especially lithium-ion batteries, chemical solvents for industrial plastics and printed circuit boards, electronic cleaners for liquid crystal displays.

The Application Of Lithium Hydroxide In The Power Battery Industry

Lithium hydroxide, CAS No. 1310-65-2, chemical formula Li(OH), is a hydroxide of lithium element. At the beginning, the main application of lithium hydroxide is not the power battery industry, but grease, such as mechanical equipment, automobiles, aircraft and so on. In 2008, the amount of lithium hydroxide used in the grease industry could account for 60%, and the battery industry accounted for 15%. Now, the main application industry of lithium hydroxide is already in the power battery market, and its ratio has reached more than 70%.
