Scaling up “Nano” Li4Ti5O12for High-Power Lithium-Ion Anodes Using Large Scale Flame Spray Pyrolysis

“…9,13,[18][19][20][21] Indeed, downsizing the particle size to the nanometer-scale resulted in excellent power performance, 21-25 allowing (dis-)charging LTObased electrodes in as little as a few seconds. However, one of the major challenges toward the commercialization of nano-sized LTO is the development of easily scalable synthesis methods, providing large batches of active material at competitive prices.…”

“…[1][2][3][4][5] However, beside advances regarding the energy density, such applications still require an improved safety, long-term cycling stability, as well as enhanced power densities with respect to state-of-the-art lithium-ion cells, commonly employing graphite as anode material. [1][2][3][4][5] Spinel-structured Li 4 Ti 5 O 12 (LTO), reported for the first time by Colbow et al in 1989, 6 is presently considered as one of the most promising alternative anode materials for realizing safer, long-lasting, high power lithium-ion batteries [7][8][9][10][11][12][13] and is, for such reasons, already utilized in commercial cells. 2 While the enhanced safety and advanced long-term cycling stability, resulting from the relatively higher lithium (de-)insertion potential and the negligible volume variation upon (de-)lithiation, [14][15][16][17] respectively, are, to a great extent intrinsic to LTO, the high power performance, i.e., the rate capability, of the material is highly dependent on the utilized synthesis method and the resulting particle size and morphology.…”

“…However, one of the major challenges toward the commercialization of nano-sized LTO is the development of easily scalable synthesis methods, providing large batches of active material at competitive prices. 13 A highly attractive method for the large-scale preparation of metal oxide nanoparticles appears to be flame spray pyrolysis (FSP). 26,27 We have recently reported the electrochemical characterization of the first generation of FSP-synthesized LTO nanoparticles, which revealed an outstanding high rate capability and long-term stable cycling performance even at elevated C rates.…”

Tailoring Iron Oxide Nanostructures for High-Capacity Lithium Storage

“…Therefore, exploring alternative anode materials with high capacity and good safety has attracted growing attention. [4][5][6][7][8][9][10][11][12][13][14][15][16] Transition metal oxides (TMOs) represent a promising family of high-capacity anode materials for LIBs. [17] Based on a conversion reaction mechanism, they are able to provide a specific capacity of 700-1000 mAh·g -1 , which is two to three times to that of graphite.…”
