摘要：

We report an amorphous titanic acid of TiO1.85(OH)(0.30)center dot 0.28H(2)O as a new electrode for aqueous ammonium-ion batteries, which operates in a new water-in-salt electrolyte-25 m NH4CH3COO. The titanic acid electrode exhibits a specific capacity nearly 8 times that from the crystalline TiO2 electrode. In electrochemical reactions, the amorphous titanic acid provides abundant storage sites in its disordered structure and affords strong H-bonding toward the inserted NH4+ ions.
