· JVASP-50732· Li4Ti3O8

Li₄Ti₃O₈ is a lithium titanium oxide ceramic compound that functions as a high-performance anode material for lithium-ion battery systems. This material is valued in energy storage applications for its exceptional cycle life, structural stability, and zero-strain insertion properties, making it particularly attractive for long-life battery chemistries where thermal stability and safety are critical concerns. Unlike conventional graphite anodes, Li₄Ti₃O₈ operates at a higher voltage plateau (~1.5 V vs. Li/Li⁺), which reduces lithium plating risks and enhances battery safety in demanding environments such as electric vehicles, grid storage, and aerospace power systems.

Regulatory Screening

Environmental

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
