Abstract

Due to extremely high conductivity of copper (Cu), copper–based nanocomposites offer remarkable opportunities for use in energy conversion and storage. Their applications demand low-cost syntheses routes relying on using inexpensive equipment with no formation of hazardous wastes. In this work, we report on a novel, cheap and environmentally friendly synthesis and application of nano-porous Cu as a support for lithium titanate. The infiltration of lithium titanate onto the inner surface of NPCu produced high-rate anodes for Li-ion batteries capable of providing nearly 50mAh/g during about 20s charging while retaining about 70% of the initial capacity after 1000 charge-discharge cycles. The demonstrated versatility and simplicity of this fascinating approach show great promises for scalable production and the use of NPCu in various cost-sensitive applications.
