This Simple Design Change Could Finally Fix Solid-State Batteries

09 Jan 2026 | Abstracted from Science Daily

Scientists at South Korea's KAIST found a simple structural redesign that could dramatically improve all‑solid‑state batteries. Instead of adding expensive metals, they rearranged the internal architecture to help lithium ions move more freely. The change boosted performance up to fourfold in tests and could lead to cheaper, safer, higher‑power batteries for phones, EVs, and other devices.
