摘要: Abstract In this study, we report a facile method to synthesize carbon-coated LiTi 2 (PO 4 ) 3 nanoporous microplates (LTP/C MPs) using ethylenediamine as the chelating agent and carbon source. The as-prepared LTP/C MPs with thickness of 0.4 μm consist interconnected nanosized particles embedded in nano-thickness layer well-dispersed nanopores. significantly improves electrochemical performance microplates. deliver reversible capacity 121 mAh g −1 at 0.2C (1C = 138 mAh g show remarkable retention 94.2% over 100 cycles when matched Li metal counter electrode. It also presents excellent properties anode material for aqueous rechargeable lithium batteries (ARLBs). MPs//LiMn O ARLB shows high discharge 76 mAh g 20 mA g superior rate capability. results suggest practical stratagem develop novel composite which is coated microplates, can become one promising electrode materials both non-aqueous ion batteries.
