It uses ultra-pure calcium hydroxide raw material, which is processed through air jet crushing and classification, with uniform particle size reaching D50=20μm, and the impurity content is controlled below 10ppm, which can effectively avoid battery short circuits caused by impurities in cathode materials. Its exclusive nano-scale surface modification process can improve the compatibility between calcium hydroxide and cathode materials, which are evenly distributed during sintering, refine grain size, improve the conductivity of cathode materials, increase the battery cycle life by more than 15% and the rate performance by about 20%.
Detailed parameters include: calcium hydroxide purity ≥99.9%, 500-mesh pass rate ≥99.5%, moisture content ≤0.1%, sodium content ≤5ppm, potassium content ≤3ppm, iron content ≤2ppm, tap density 0.7-0.9 g/cm³. The product is packaged in 5kg aluminum foil vacuum bags, and the outer package uses anti-static cartons. It needs to be stored in a dust-free clean room, the temperature is controlled at 15-25℃, relative humidity ≤30%, and avoid contact with any organic impurities.
It is mainly used for doping modification of lithium iron phosphate cathode materials, sintering additives for ternary lithium cathode materials, and interface modification materials for solid-state battery electrolytes. It can be added at a ratio of 0.5%-2% during the production of lithium battery cathode materials, improving the compaction density and ion conductivity of cathode materials. It is suitable for high-end application scenarios such as new energy vehicle power batteries, energy storage batteries, and consumer electronic batteries, and conforms to UL and IEC battery material safety standards.
