  • Patent number: 11011782
    Abstract: A method of prolonging service life of an energy storage device such as a lithium-ion battery includes temporarily operating the battery at an elevated current density. Cycling of lithium-ion batteries at regular current densities results in the generation of lithium-metal dendrites at the surface of the anode, particularly in batteries where the anode is lithium metal. The lithium metal dendrites pose a threat to damage other components of the battery, such as separators, as well as causing an electrical short. Operating the battery in bursts at the elevated current density results in self-heating at the anode surface that merges adjacent lithium-metal dendrites and an overall smoothing of the anode surface. This method is also applicable to other alkali-metal-based batteries and chemistries.
