چکیده انگلیسی


• Two kind of urea formaldehyde resin (UFR) with wider size distribution were successfully fabricated.
• The prepared UFR provide a structurally robust scaffold into which the hydrothermally synthesized LiFePO4 particles could extrude.
• The prepared bulk electrode have hierarchically, well-ordered and interconnected pore structure.
• The prepared bulk electrodes exhibited higher volumetric energy density, superior rate capability and stable cycling life.

Current-collector-, binder-free and three-dimensional (3D) bulk electrodes with hierarchically porous architecture have been prepared via using different-sized urea formaldehyde resin (UFR) as templates. The prepared 3D bulk electrodes, consisting of active material, rapid ion and electron transport pathways, have millimetric electrode thickness. Higher volumetric capacity and superior rate capability simultaneously are achieved. This work enlighten a way to obtain high power and energy density electrode.
