2014-010 – Superior, High-Performance Electrode For ‘Paintable’ Lithium-Ion Batteries

Existing Lithium-ion battery electrodes demonstrate very low stable charge capacity either at high current densities or at half weight, making them unsuitable for high-power applications. Researchers at KSU have developed a high-performance ‘paintable’ Lithium-ion battery anode comprising of SiAlCN-Carbon Nanotube (CNT) composite that is spray-painted on a metallic or ceramic substrate (e.g. copper). The electrode demonstrates extremely high stable charge capacity per weight and per area of electrode as well as at high current densities, when used in a Lithium-ion battery. The key aspect of this electrode is that it demonstrates significantly higher stable charge capacity than existing graphite electrodes, even after the first cycle loss of Lithium. In addition, the ‘paintable’ nature of these electrodes on a variety of substrates allows for the creation of superior, high-performance Lithium-ion batteries that could possibly be easily integrated into common electronics.
