| La2Ti2O7 nanosized powder was prepared and evaluated as novel negative electrode materialfor Ni/oxide rechargeable batteries. La2Ti2O7nanosized powder was synthesized at 850◦Cwithin 5 h by the well-known citric-acid sol–gel route. The synthetized powder had an irregular morphology with a particle size below 100 nm and a tendency to form clusters. La2Ti2O7had a perovskite-type layered structure and presented a maximum electrochemical hydrogen uptake capacity of 224 mA h/g corresponding to 0.84 wt.% of hydrogen. Electrochemical studies revealed that the La2Ti2O7compound can be considered an alternative electrode material for Ni/oxide rechargeable batteries since it exhibits a good cycling stability aftera activation.
