Increasing reversible capacity of soft carbon anode by phosphoric acid treatment

Soft carbon with a high reversible capacity has been proposed as an anode material for high-power lithium ion batteries. In this work, we investigate the effect of phosphoric acid (H3PO4) addition during preparation on the microstructure and electrochemical performance of soft carbon. H3PO4 facilitates the formation of nanopores by terminating C-C bonding and forming C-Ox-P (0
