  "textContent": "Bonding lithium metal to a ceramic surface should be a dream team combination for creating solid-state lithium metal batteries. However, getting them to bond is the hard part. Impurity layers tend to form on the surface, which hinders a process called wetting that is crucial to the adherence of metals and ceramics. To get these two materials with very different characteristics to bond, a different strategy was needed. Researchers at Tohoku University's Advanced Institute for Materials Research (WPI-AIMR) thought outside the box, finding that ultrasonic welding brought these two materials together.",
