An Electron/Ion Dual

Thus, the capacity, current density, and cycle life of the solid Li anode are improved. The cycle capability of this solid anode is demonstrated by cycling for 500 h at 1 mA cm -2, followed by another 500 h at 2 mA cm -2 without short-circuiting, realizing a record high cumulative capacity of 750 mA h cm -2 for garnet-type all-solid-state Li batteries.
