| 中文摘要: |
| 全固态锂离子电池具有安全性能好、能量密度高、工作温区广等优点,被广泛应用在便携式电子设备。固态电解质是全固态锂离子电池的关键材料,其中的硫化物电解质具有离子电导率高、电化学窗口宽、晶界电阻低和易成膜等特点,被认为最有希望应用在全固态锂离子电池。本文综述了Li2S-P2S5体系电解质的发展状况,包括固态电解质的制备、改性、表征以及电极/固态电解质之间的固-固界面的稳定兼容问题。本文还涉及了以Li2S-P2S5为电解质的全固态锂离子电池性能的研究进展。 |
| 英文摘要: |
| All-solid-state lithium-ion batteries have been widely used in portable electronic devices, due to their advantages of good safety, high energy density, wide working-temperature range, etc. The Solid electrolytes are the key material of all-solid-state lithium-ion batteries. Among various electrolytes, the sulfide-based materials have the characteristics of high ionic conductivity, wide electrochemical window, low grain boundary resistance and easy film formation, which are promising to be used in all-solid-state batteries. In this paper, we focused on the recent progress of the solid electrolytes with respect to the preparation, characterization and modification of Li2S-P2S5 electrolytes, and stability/compatibility of the interface between the solid electrolyte and the electrode. Moreover, the performance of these solid electrolyte related all-solid-state lithium-ion batteries has also been reviewed. |
