Nontraditional, Safe, High Voltage Rechargeable Cells of Long Cycle Life

A room-temperature all-solid-state rechargeable battery cell containing a tandem electrolyte consisting of a Li+-glass electrolyte in contact with a lithium anode and a plasticizer in contact with a conventional, low cost oxide host cathode was charged to 5 V versus lithium with a charge/discharge cycle life of over 23,000 cycles at a rate of 153 mA·g–1 of active material. A larger positive electrode cell with 329 cycles had a capacity of 585...
