Carbon-coated Li3Nd3W2O12 : a high power and low-voltage insertion anode with exceptional cycleability for Li-Ion batteries
The synthesis of carbon-coated Li3Nd3W2O12 (C-Li3Nd3W2O12), a low voltage insertion anode (0.3 V vs. Li) for a Li-ion battery, is reported to exhibit extraordinary performance. The low voltage reversible insertion provides an increase in the energy density of Li-ion power packs. For instance, C-Li3N...

| Summary: | The synthesis of carbon-coated Li3Nd3W2O12 (C-Li3Nd3W2O12), a low voltage insertion anode (0.3 V vs. Li) for a Li-ion battery, is reported to exhibit extraordinary performance. The low voltage reversible insertion provides an increase in the energy density of Li-ion power packs. For instance, C-Li3Nd3W2O12 delivered an energy density of ≈390 Wh kg−1 (based on cathode mass loading) when coupled with an LiMn2O4 cathode with an operating potential of 3.4 V. Furthermore, excellent cycling profiles are observed for C-Li3Nd3W2O12 anodes both in half and full-cell configurations. The full-cell is capable of delivering very stable cycling profiles at high current rates (e.g., 2 C), which clearly suggests the high power capability of such garnet-type anodes. |
