“…The electrochemical stability of polymer electrolytes has long been considered a main challenge for SSE applications in high voltage battery systems. Therefore, cathodes with low charge/discharge platform, such as LiFePO 4 and V 2 O 5 , , were usually utilized in solid polymer lithium batteries. LSV was performed to examine the electrochemical window of solid polymer electrolytes, and it was reported that the electrochemical stability of polyether-derived electrolytes was in the range 3.7–4.5 V. ,, …”

Solid-state batteries have been attracting wide attention for next generation energy storage devices due to the probability to realize higher energy density and superior safety performance compared with the state-of-the-art lithium ion batteries. However, there are still intimidating challenges for developing low cost and industrially scalable solid-state batteries with high energy density and stable cycling life for large-scale energy storage and electric vehicle applications. This review presents an overview on the scientific challenges, fundamental mechanisms, and design strategies for solid-state batteries, specifically focusing on the stability issues of solid-state electrolytes and the associated interfaces with both cathode and anode electrodes. First, we give a brief overview on the history of solid-state battery technologies, followed by introduction and discussion on different types of solid-state electrolytes. Then, the associated stability issues, from phenomena to fundamental understandings, are intensively discussed, including chemical, electrochemical, mechanical, and thermal stability issues; effective optimization strategies are also summarized. State-of-the-art characterization techniques and in situ and operando measurement methods deployed and developed to study the aforementioned issues are summarized as well. Following the obtained insights, perspectives are given in the end on how to design practically accessible solid-state batteries in the future. CONTENTS 1. Introduction 6822 2.

“…However, the oxidation decomposition of the SPE takes place at over 4 V vs Li/Li + . Therefore, the most commonly reported cathode materials for the LPB have been 3V-class ones (e.g., V 2 O 5 − and LiFePO 4 , ), and the research and development (laboratory scale) of 4V-class (e.g., LiCoO 2 and LiMn 2 O 4 ) LPB systems is now in progress.…”

For the purpose of oxidation decomposition control of the polyether-based solid polymer electrolyte (SPE) in the high-voltage state, lithium phosphate (Li3PO4)-coated cathode (LiCoO2) powder was prepared via a mechanical coating technique. An all-solid-state lithium polymer secondary battery that used Li3PO4-coated LiCoO2 was prepared. By the oxidation suppression enabled by the Li3PO4 that was intervened between SPE and LiCoO2, charging up to a high voltage (4.6 V vs Li/Li+) was made possible and the discharge capacity was observed to be over 200 mAh g-1. Detailed electrochemical analysis was enabled by a combination of constant current−constant voltage charging measurements and electrochemical impedance spectroscopy (EIS). As a result, it became clear that the oxidation decomposition that takes place at the SPE/cathode interface can be controlled by a coating of Li3PO4 on LiCoO2.

“…Against this background, various electrolytes (i.e., solid polymers, [2][3][4][5][6][7][8][9] inorganic electrolytes, [10][11][12] and room-temperature ionic liquids [13][14][15][16][17][18][19][20] ) have been considered as possible safe materials for lithium-ion batteries. Recently, good compatibilities of solid polymers or room-temperature ionic liquids with carbon-based negative electrodes (for example, graphite and hard carbon) as well as with conventional organic liquid electrolytes (for example, EC/DMC-LiPF 6 ) have been reported.…”

Electrolyte performance of CH 3 -(OC 2 H 4 ) 3 -CH 3 (TG)/LiN(SO 2 F) 2 (LiFSI) 1:1 molar mixture was investigated for high-safety lithium-ion secondary batteries by various physicochemical and electrochemical measurements. The TG-LiFSI electrolyte formed 1:1 complex, and showed relatively high thermal stability. Stable charge/discharge (intercalation/deintercalation) of lithium ions with both LiFePO 4 positive electrode and graphite negative electrode were enabled with high coulombic efficiency and long cycles. Moreover, long cycle charge/discharge operations of [LiFePO 4 positive electrode|TG-LiFSI electrolyte|graphite negative electrode] cell was achieved with 82% of capacity retention at 100 cycles.
