Mesoporous Metal Oxide with High Packing Density for Superior Lithium Storage

Industry Problem

Li-ion battery is a promising rechargeable battery technology, but still requires the development of efficient cathode and anode materials in order to increase Lithium storage capacity. Electrode materials with nanometer-sized grains (nanostructured) enables efficient diffusion of both Li-ions and electrons. However, conventional nanostructured materials eg. nanopowders has low packing density resulting in low volumetric energy density. Hence, there is a need for an electrode material with high packing density and good lithium storage capacity.

Solution

Prof Palani Balaya’s group from the Department of Mechanical Engineering has developed a nanostructured mesoporous TiO2 which shows not only superior lithium storage capacity, but also excellent rate performance and cyclic stability without any conductive surface coatings such as RuO2 or carbon. Most importantly, we demonstrate a high packing density at least 6 times higher than the commercially available TiO2 nanopowder, which enables development of smaller size batteries. The mesoporous TiO2 material exhibits superior storage capacity ((~288mAh/gat0.2CrateforC16-TiO2) compared to commercially available TiO2 (~60-80mAh/gat0.2Crate).




Value Proposition

·  Smaller size batteries with excellent storage performance (high storage capacity of 265 mAh/g at 0.2C rate)

·  High storage capacities at high rate of charging/discharging current (107 mAh/g at 30C rate)

·  High packing density of at least 6 times higher than the commercially available TiO2nanopowder

Other Potential Application

·  Batteries

·  Dye-sensitized Solar Cell (DSSC)

·  Sensors
