Abstract

In this research, the phosphorus-doped carbon-decorated Li4Ti5O12 composite (denoted as Li4Ti5O12 @PC) has been fabricated for the first time using a facile sol-gel-assisted solid-state approach. The effects of P-doping on the crystal structure, morphology and lithium storage property of Li4Ti5O12 @PC are investigated in detail. When used as anode for Li-ion batteries, it presents outstanding rate capacity (143.3 mAh g−1 at 15 C) and cycle-life stability (156.8 mAh g−1 at 5 C after 300 cycles). The excellent lithium storage property is attributed to the coated P-doped carbon layer which can inhibit the growth of Li4Ti5O12 nanoparticles during the synthesis process and provide high conductivity transport pathway for electron. This novel “P-doped carbon coating” strategy can be extended to fabricate other high-property electrodes for energy storage.
