英文摘要Red phosphorus has been widely studied as the most promising anode material for sodium ion batteries (NIBs) with an ultrahigh theoretical capacity of 2596mA h g(-1). However, its poor intrinsic electronic conductivity and huge volume change during the continuous sodiation/desodiation process lead to sluggish sodium ion diffusion kinetics and severe pulverization of the electrode material, resulting in severe capacity decay. In this study, a rationally designed P/C anode material of nitrogen doped porous carbon tubes (N-PCTs) with tiny red P embedded into the pores is successfully fabricated. The formed P-C chemical bonds could facilitate robust and intimate contact between red P and the carbon matrix and the robust structural integrity is confirmed by our in situ transmission electron microscopy (TEM) study of the sodiation/desodiation cycle. Benefiting from the synergistic effect of the physical confinement of the pores in the carbon matrix and the chemical adsorption due to the P-C chemical bonding, superior long-term cycling stability (1157 mA h g(-1) at 2 A g(-1) after 100 cycles) as well as excellent rate capability (572 mA h g(-1) at 10 A g(-1)) could be obtained.
