| Popis: | Electrophoretically deposited Nickel Titanate (NTO)-graphene oxide (GO) composite is proved as a promising anode for both lithium and sodium ion batteries. The optimized electrode delivers a high discharge capacity of 877 and 790 mAhg−1 against lithium and sodium with improved capacity retention (~506 & 290 mAhg−1) even after 100 cycles because of the synergistic effects between GO and NTO nanoparticles. Uniform distribution of active material, carbon black and GO in the EPD grown electrode as well as its superior adherence with the current collector might be responsible for improved electrochemical performance. |
