Phosphorus@carbon composites are
alternative anode materials for
lithium-ion batteries due to their high specific capacity. Serving
as a conductive and buffer matrix, the carbon substrate is important
to the performance of the composite. Our results exhibit that the
electrochemical performances of phosphorus@carbon composites could
be significantly enhanced by pore size distributions of the carbon
matrix. The initial Coulombic efficiency of phosphorus@YP-50F reaches
80% and the capacity remains stable at 1370 mAh g<sup>–1</sup> after 100 cycles at 300 mA g<sup>–1</sup>. The work may provide
a general strategy for designing or selecting the optimal carbon matrix
for phosphorus@carbon performance, and pave the way to practical application
in lithium-ion batteries
