An energy storage electrode and a device can be fabricated from Ultrafine Metal Mesh (UMM). Deposited onto the said UMM surfaces are electrode materials including electrochemically active materials and electrolytes, producing UMM-based electrodes. Lamination of alternately stacked positive and negative UMM-based electrodes results in high performance energy storage devices including supercapacitors, Li-ion batteries, and Li metal batteries. The energy storage device shows improved energy and power characteristics resulting from the 3-D architectures of the UMM-based energy storage devices.
