Description
Chen Yu, Jiarui Yang, Deyan Luan, and Xiong Wen Lou design a host frame for lithium metal battery anodes, in a 2026 study. Lithium metal promises far more stored energy than today's cells, yet it plates unevenly and swells, which ruins cycle life. Leaning on excess lithium hides the flaw but wastes the gain. Their host is a hollow iron phosphate rod wrapped in a nitrogen laced carbon shell.
Electrodes cast with the rods guided smooth, even lithium plating and curbed swelling. Deep chemical probes showed the iron compound seeds a helpful surface film rich in two lithium salts. Cells ran steady for fourteen hundred hours of plating and stripping with small voltage drift. A full cell with a lean lithium share kept about four fifths of its capacity past one hundred cycles.
