【摘要】 采用烧结法,在严格制定的热处理制度下制备了Li2O-Al2O3-GeO2-SiO2-P2O5系统玻璃陶瓷电解质材料。XRD分析表明对该组分的玻璃产物,800℃热处理12h的产物具有最完善的晶相,交流阻抗测试得到最佳产物的室温锂离子电导率高达1.95×10-4 S/cm,其高的锂离子电导率、优良的抗热性能和简单的制备工艺表明这种材料是很有潜力的全固态锂离子电池用固体电解质。更多还原

【Abstract】 A Li2-Al2O3-GeO2-SiO2-P2O5 glass-ceramics was prepared by means of sintering under the precise treating process. X-ray diffraction analysis indicated that the crystal phase of the glass-ceramics treated at 800℃ for 12 h was the best. The highest value of the lithium ion conductivity was 1.59×10-4 S/cm at room temperature for the specimen treated at 800℃ for 12 h. The high conductivity, good heat-resistance and easy fabrication of Li1.8Al0.4Ge1.6Si0.4P2.6O12 glass-ceramics suggest they are promising solid electrolytes for all-solid state Li-ion rechargeable batteries.更多还原
