▎ 摘　　要

NOVELTY - Battery 100 comprises cathode, anode is positioned opposite the cathode. The anode comprises first thin film which is deposited on current collector. The first thin film includes first multiple of aggregates 132 decorated with first multiple of metal nanoparticles and joined together to define first porous structure 136 has first conductivity and second thin film is deposited on the first thin film. The second thin film includes second multiple of aggregates decorated with second multiple of metal nanoparticles and joined together to define second porous structure having second conductivity that is different than the first conductivity and lithium layer is deposited on the first and second porous structures. The lithium layer has thickness greater than 20 microns. 138 Metal nanoparticles 134 USE - Battery . ADVANTAGE - The battery improves specific capacity of the host structure. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of battery. Battery (100) Aggregates (132) Metal nanoparticles (134) First porous structure (136) Host structure (138)
