▎ 摘　　要

NOVELTY - Battery 100 comprises an anode 120 including an alkali metal configured to release many alkali ions during cycling of the battery, a polymeric network deposited over exposed surfaces of the anode, a cathode 110 positioned opposite to the anode, an electrolyte 130 partially dispersed throughout the cathode and in contact with the anode, and a separator positioned between the anode and the cathode, where the polymeric network includes carbonaceous materials grafted with fluorinated polymer chains cross-linked with each other, the fluorinated polymer chains are configured to produce an alkali-metal fluoride in response to operational cycling of the battery, the alkali-metal fluoride is configured to suppress alkali metal dendrite formation from the anode, and the electrolyte is configured to transport the alkali ions between the cathode and the anode. USE - Battery, preferably lithium-ion or lithium-sulfur battery used to provide electric power to devices such as mobile phones, laptops, electric vehicles, factories and buildings. ADVANTAGE - The battery can compensate for operational cycle losses. DESCRIPTION OF DRAWING(S) - The drawing shows a battery.
