方向1:全钒液流电池隔膜

全钒液流电池具有容量和功率可调、大电流无损深度放电、使用寿命长、易操作和维护、氧化还原电对由单一金属离子(钒离子)构成、无交叉污染等优点。因此,全钒液流电池非常适用于调峰电源系统、大规模光电转换系统、风能利用系统、电动汽车电源等方面。目前,全钒液流电池使用的隔膜通常是具有高质子传导率和优异化学稳定性等优点的全氟磺酸基隔膜材料,如美国杜邦公司生产的Nafion型系列膜。然而,Nafion型隔膜的钒离子渗透率高、质子选择性低,从而使电池的自放电严重,且其成本达到整个电池体系的40%以上。因此,亟待开发可替代Nafion膜的新型隔膜材料。具体研究内容如下:(1)采用新型功能单体合成及分子调控策略,开发具有新型分子结构的膜材料;(2)采用功能性增强剂引入策略,构建复合膜材料;(3)采用“实验+计算”的手段阐明所创制膜材料的失效机理
