Xidian University Develops Thin Protective Coating for Lithium Metal in Solid-State Batteries

Researchers at Xidian University have developed a thin liquid protective coating for solid-state batteries. The coating reacts with lithium metal to form a protective barrier. In laboratory tests, solid-state batteries using lithium metal treated with this method retained 82.3% of their capacity after 300 charge-discharge cycles, compared with 43.0% for batteries using untreated lithium metal. The findings have been published in the journal Science China Chemistry.
