Lithium-Ion Batteries: Solid Electrolyte: the Key for High-Voltage Lithium Batteries (Adv. Energy Mater. 4/2015).

High‐voltage (5 volt) lithium‐ion chemistry is realized with Lipon, a glass solid electrolyte. In article number 1401408, Juchuan Li, Nancy J. Dudney, and co‐workers describe the battery, which consists of a LiNi0.5Mn1.5O4 spinel cathode and a lithium metal anode. This solid‐state battery delivers a high coulombic efficiency of >99.98% and stable cycling of >90% retention for 10 000 cycles. [ABSTRACT FROM AUTHOR]
