Abstract

We developed a simple and scalable chemical method to obtain phosphorus-doped porous carbon (P-PC–RH) by optimized acid treatment and thermal annealing of rice husk with triphenylphosphine (TPP). After doping with phosphorus (doping level of ∼4.14 at% P), the P-PC–RH electrode increases by almost half the reversible capacity (757 mA h g⁻¹ after 100 cycles at 100 mA g⁻¹) of porous carbon without phosphorus doping (PC–RH-x, x = 2, 4, 6). When cycled at a high current of 2000 mA g⁻¹, it still delivers a reversible specific capacity of 382 mA h g⁻¹. The improved electrochemical performance of P-PC–RH is attributed to the synergetic effect of the 3D interconnected porous structure and phosphorus doping, which can maintain perfect electrical conductivity throughout the electrode and enhance electrochemical activities for lithium storage.
