Description
Yunyi Chen, with seven colleagues, presents a 2026 design for lithium metal batteries that start with no anode at all. Such cells pack more energy and are simpler to build, since lithium plates onto a bare copper sheet on first charge. The snag is poor reversibility: lithium plates and strips unevenly, grows spikes, and dies fast.
The team added a silver-based starter mix to the electrolyte. Silver ions settle on the copper and make it welcome lithium, while partner ions trigger a skin that forms in place and can heal itself. That skin flips the usual layout, with an organic-rich inner layer and a mineral-rich outer layer. A test cell kept 90 percent of its capacity after 200 cycles. A 2 amp-hour pouch cell reached 467 watt-hours per kilogram.
