Titanium diborides were investigated as an anodic material for neutral aqueous batteries.It is revealed that this material shows superiorly high electrochemical activities in the neutral electrolytes.The discharge capacities observed for TiB2 reached 1300 mAh/g at the constant current density of 50 mA/g,exceeding all the metal electrodes reported so far.The electrooxidation of this compound was found to proceed via the electrochemical dissolution of boron to form borofluoride,while titanium remained unchanged at the electrode.These results suggest a possible use of the boride compounds as a new material for constructing neutral aqueous batteries with high electrochemical capacity and rate capability.
