Description

As the need for better means of energy storage is on the rise, lithium ion batteries show promise in meeting society’s energy storage necessities, due to their ultra-high capacity after many cycles and high energy density. The use of new, conductive two-dimensional transition metal carbide materials, known as MXene (Ti3C2), has the potential to increase overall performance of lithium ion batteries. Here we present a novel lithium ion battery with the anode electrode comprised of a nanocomposite, MXene/Sn. Initially, MXene is synthesized by aluminum exfoliation of Ti3AlC2 (MAX) powder. MXene is shown to have a high capacitance due to its layered geometry and complex composition that allows for efficient intercalation of Li+ ions. Sn nanoparticles were then dispersed uniformly throughout the layers to form MXene/Sn nanocomposite. The MXene/Sn nanocomposite demonstrates a high capacitance and significantly improved efficiency for lithium ion batteries.
