title: A novel tunnel Na(0.61)Ti(0.48)Mn(0.52)O₂ cathode material for sodium-ion batteries.
abstract: A novel tunnel Na(0.61)Ti(0.48)Mn(0.52)O2 material is explored as a cathode for sodium-ion batteries for the first time. It can deliver a reversible discharge capacity of 86 mA h g(-1) with an average voltage of 2.9 V at 0.2 C rate in a sodium half cell, exhibiting good rate capability and capacity retention at a cut-off voltage of 1.5-4 V. These results indicate that tunnel Na(0.61)Ti(0.48)Mn(0.52)O2 has a great potential application in large scale energy storage.
