In situ fabrication of lithium titanium oxide by microwave-assisted alkalization for high-rate lithium-ion batteries

Abstract

A phase-pure Li₄Ti₅O₁₂/reduced graphene oxide nanocomposite was prepared using a simple one-pot synthesis of the Li–Ti–O precursor and subsequent heat treatment. The prepared nanocomposite delivers a reversible capacity of 168 mA h g⁻¹ at 1 C-rate and a remarkable rate capability with 59% capacity retention at 50 C-rate.
