Scientists in China have developed a thin protective coating that could help overcome a major obstacle to longer-lasting, high-capacity batteries. In laboratory tests, solid-state batteries using the treated lithium metal retained 82.3% of their initial capacity after 300 charging cycles, compared with just 43.0% for batteries using untreated lithium.
The researchers at Xidian University developed a simple liquid coating that reacts with lithium metal to form a protective barrier. Their findings, published in Science China Chemistry, suggest a possible route toward safer, more durable batteries for electric vehicles and energy storage.
