Three-dimensional lion's mane like AlV3O9 deposited on graphene surface for supercapacitors with a promising electrochemical performance

3D lion's mane like AlV3O9 microspheres deposited on the well-exfoliated graphene were successfully synthesised through a facile solvothermal method where the graphene sheet was prepared solely via the liquid phase exfoliation process. The highly electrical conductive graphene was introduced as a conductive substrate or a backbone to support the diffusion of the electrolyte ions (OH-).
