原始语种摘要: Abstract(#br)Despite of poor electrical conductivity and large volume expansion, low mass loading of phosphorus-based electrode severely decrease overall gravimetric/volumetric energy density, impeding its practical application in lithium ion batteries (LIBs). Herein, we construct a high-areal-capacity P@rGO-ACW electrode by warping phosphorus with rGO and confining in 3D microchanneled carbon matrix (P@rGO-ACW). The conductive 3D carbon scaffold (ACW) derived from natural wood acts as integrated porous current collector to accelerate the electrons/ions transport, while the vertical-alignment microchannels confine phosphorus and accommodate its volume expansion. The unique feature of phosphorus‑carbon electrode with 3D aligned nanochannels allows for a considerable improvement in...
