Abstract
Na2Ti3/2Mn1/2(PO4)3 nanodots uniformly planted in a carbon matrix are reported for the first time as a promising low-cost anode for aqueous sodium-ion batteries, showing ultrafast Na-intercalation chemistry with stable capacities of 78.8 mA h g-1 at 0.5C and 65.1 mA h g-1 at 10C, and a capacity retention of 93% after 200 cycles.
