Abstract

All‐solid‐state rechargeable batteries are regarded as one of the most promising next‐generation energy storage devices, while their cycling stability is still a great challenge due to the nonuniform lithium ion transportation and the loss of active lithium during cycling. Herein, a LiF embedded prelithiated graphite interface layer is designed and inserted between Li6PS5Cl solid electrolyte layer and graphite anode layer. The presence of LiF, C−F bonds and prelithiated graphite in this unique interface layer can facilitate uniform lithium ion migration and compensate the loss of active lithium, thus significantly improving the cyclic performances of both monopolar and bipolar all‐solid‐state lithium ion batteries. After 100 cycles at 0.1 C, the capacity retention increases from 58 % to 78.5 % for the monopolar LiNi0.5Co0.2Mn0.3O2|Li6PS5Cl|LiF@2.5 %Li@G|graphite all‐solid‐state lithium ion battery. Besides, the bipolar all‐solid‐state lithium ion batteries show a high discharge plateau of ~7.6 V with a capacity retention of 60.2 % after 190 cycles at 0.1 C. This work demonstrates the effectiveness of LiF embedded prelithiated graphite interface layer for improving the electrochemical performances of all‐solid‐state lithium ion batteries.

Abstract

Lithium‐oxygen batteries have received great research interest owing to their ultrahigh theoretical energy density and are considered as one of the promising secondary batteries. However, there are still some challenges in their practical application, like liquid organic electrolyte evaporation in the semi‐open system and instability in the high‐voltage oxidizing environment. In this work, a cellulose acetate‐based gel polymer electrolyte (CA@GPE) is proposed, whose cross‐linked microporous structure ensures the ultrahigh liquid electrolyte uptake of 2391%. The prepared CA@GPE exhibits a high lithium‐ion transference number of 0.595, a satisfying ionic conductivity of 0.47 mS cm−1 and a wide electrochemical stability window up to 5.0 V. The Li//Li symmetric cell employing CA@GPE could cycle stably over 1200 h. The lithium‐oxygen battery with CA@GPE presents a superb cycling lifetime of 370 cycles at 0.1 mA cm−2 under 0.25 mAh cm−2. This work offers a possible strategy to realize long‐cycling stability lithium‐oxygen batteries. [ABSTRACT FROM AUTHOR]
