Abstract
Easy-to-manufacture Li2S-P2S5 glass ceramics are the key to large-scale all-solid-state lithium batteries from an industrial point of view, while their commercialization is greatly hampered by the low room temperature Li+ conductivity, especially due to the lack of solutions. Herein, we propose a nanocrystallization strategy to fabricate super Li+-conductive glass ceramics. Through regulating the nucleation energy, the crystallites within glass ceramics can self-organize into hetero-nanodomains during the solid-state reaction. Cryogenic transmission electron microscope and electron holography directly demonstrate the numerous closely spaced grain boundaries with enriched charge carriers, which actuate superior Li+-conduction as confirmed by variable-temperature solid-state nuclear magnetic resonance. Glass ceramics with a record Li+ conductivity of 13.2 mS cm−1 are prepared. The high Li+ conductivity ensures stable operation of a 220 μm thick LiNi0.6Mn0.2Co0.2O2 composite cathode (8 mAh cm−2), with which the all-solid-state lithium battery reaches a high energy density of 420 Wh kg−1 by cell mass and 834 Wh L−1 by cell volume at room temperature. These findings bring about powerful new degrees of freedom for engineering super ionic conductors. © 2023, The Author(s).
