This standard comprehensively specifies the technical requirements for lithium titanate and its carbon composite anode materials, covering the entire process from terminology definitions and classification codes to performance indicators and inspection rules. The standard not only clearly defines the material's appearance and physicochemical properties, such as particle size distribution, pH value, and tap density, but also emphasizes key electrochemical performance indicators, including initial charge-discharge efficiency and cycle life. For testing methods, it stipulates the use of laser particle size analyzers for particle size distribution analysis, BET gas adsorption for specific surface area measurement, and strict moisture content control via Karl Fischer moisture analyzers. Additionally, precise chemical composition analysis is often conducted using Inductively Coupled Plasma Mass Spectrometry (ICP-MS), while the identification of the material's crystal structure relies on X-ray Diffraction (XRD). This provides solid technical support for ensuring the high safety and long cycle life of lithium-ion battery anode materials.
