Economic and High Performance Phosphorus-Carbon Composite for Lithium and Sodium Storage.

ABSTRACT: Porous carbon derived from rice hulls has potential for application in phosphorus-carbon composites as high capacity anode materials for lithium-ion and sodium-ion batteries. The native composition of rice husks produces a porous carbon with a unique doped structure, as well as an efficient pore and channel structure, which may facilitate high and stable lithium storage. After cycling for over 100 cycles, the composite delivered a capacity of about 1293 mAh g^-1, as well as a coulombic efficiency of nearly 99% at the current density of 130 mA g^-1 with a capacity density of 1.43 mAh cm^-2. High specific discharge capacities were maintained at different current densities (∼2224, ∼1895, ∼1642, and ∼1187 mAh g^-1 _composite at 130, 260, 520, a
