Next generation high energy density and ultrafast charging lithium-ion battery technology requires fast charging anodes with high capacity, low volume expansion during cycling and moderate operating voltage. Li4Ti5O12 (LTO) is the only commercially available anode material that has the ability to safely fast charge in 5 mins with minimal expansion on intercalation of lithium-ions. However, it suffers from poor energy density and low capacity (<160 mAh/g) and poor electronic, ionic conductivities. Echion Technologies Ltd has developed “Mixed Niobium Oxide” -based anodes that it has commercialised to solve these issues, offering the ability to fast-charge in under 5 mins and maintain a long lifetime, with double the volumetric capacity of LTO materials (>640 mAh/cm3). In general, mixed niobium oxide materials [1,2] are intrinsically insulating and require improvement in electronic conductivity (by materials/particle engineering) for minimising impedance effects at the cell level. Material parameters (particle morphology, size distribution, microstructure), degradation mechanism and ageing of anodes play a vital role towards scalability of optimised materials for commercial devices and tailored applications. The different scalable synthesis techniques, processing parameters and their effect on material characteristics, electrochemical performances will be discussed in this talk. The critical challenges faced by industry towards scalability of materials and commercial devices will also be reviewed.[1] Jian-Tao Han et.al., Chem. Mater., 23 (2011) 2027-2029.[2] M.
