Super high-rate, long cycle life of europium-modified, carbon-coated, hierarchical mesoporous lithium-titanate anode materials for lithium ion batteries

Abstract

Li_4−x/2Ti_5−x/2Eu_xO₁₂@C (<italic>x</italic>= 0.004) was prepared<italic>via</italic>the co-precipitation method. When cycled at 100 C, the discharge capacity stayed at 92.1 mA h g⁻¹.
