| 英文摘要 | Developing solid-state electrolytes with good compatibility for high-voltage cathodes and reliable operation of batteries over a wide-temperature-range are two bottleneck requirements for practical applications of solid-state metal batteries (SSMBs). Here, an in situ quasi solid-state poly-ether electrolyte (SPEE) with a nano-hierarchical design is reported. A solid-eutectic electrolyte is employed on the cathode surface to achieve highly-stable performance in thermodynamic and electrochemical aspects. This performance is mainly due to an improved compatibility in the electrode/electrolyte interface by nano-hierarchical SPEE and a reinforced interface stability, resulting in superb-cyclic stability in Li||Li symmetric batteries (>4000聽h at 1聽mA聽cm鈭?/1聽mAh聽cm鈭?; >2000 h at 1聽mA聽cm鈭?/4聽mAh聽cm鈭?), which are the same for Na, K, and Zn batteries. The SPEE enables outstanding cycle-stability for wide-temperature operation (15鈥?00 掳C) and 4 V-above batteries (Li||LiCoO2 and Li||LiNi0.8Co0.1Mn0.1O2). The work paves the way for development of practical SSMBs that meet the demands for wide-temperature applicability, high-energy density, long lifespan, and mass production. 漏 2021 Wiley-VCH GmbH |
