Abstract:
An ultrafine SnO2 confined N,P,S-doped helical carbon nanotube (SnO2@NPSC) is developed as an anode for lithium-ion batteries. The unique skeleton, featuring physical confinement and chemical bonding, effectively suppresses the volume expansion and migration of the active metal, achieving excellent electrochemical performance. It provides a valuable reference for developing conversion-alloying anode materials.
