High-purity aluminum oxide powder for lithium battery separators.
- Commodity name： High-purity aluminum oxide powder for lithium battery separators.
- =Main purpose： 1. Lithium battery separator coating 2. Transparent ceramics 3. Polishing abrasives
- =Product overview： Lithium battery separator series products, coated with a ceramic layer on the separator between the positive and negative electrodes of lithium batteries, serve to provide heat resistance, high-temperature resistance, and insulation, thereby preventing short circuits in power batteries due to excessive temperatures causing the separator to melt. Features: 1. High purity, non-toxic, harmless, and environmentally friendly; 2. Excellent high-temperature resistance, making it a ceramic isolator with outstanding insulation properties; 3. Moderate particle size, with an average particle diameter of 50.
