Red phosphorus (RP), as one of the most promising anode materials for lithium-ion batteries, attracts much attention for its high theoretical specific capacity, cost-effective, and commercial availability. However, poor cycling stability and rate capability caused by huge volume expansion and low intrinsic electronic conductivity hinder the commercialization of RP-based anode. Herein, RP confined in ultrathin hollow carbon-bubble-constructed foam (RP-HC) is developed to improve electronic conductivity and mechanical structure stability. Additio...
