Extending the lifespan of lithium-metal batteries using a fluorinated ether diluent

May 24, 2024


The design of battery technologies with increasingly longer lifespans could help to meet the growing needs of the electronics and automotive industry. Lithium (Li) batteries are the most widely used rechargeable batteries worldwide. Thus, devising strategies that can increase their longevity could be far easier than designing entirely new batteries.

Li-metal batteries, batteries with a Li metal anode, are among the most promising next-generation battery designs. Nonetheless, the reactivity of Li metal has so far greatly limited their cycling stability, by impairing the formation of stable solid-electrolyte interphases (SEIs), ultimately resulting in shorter battery lifespans.
