近年来,随着锂离子电池技术的发展,动力锂离子电池(LiFePO4/C)的应用技术得到了长足的进步,但安全性能仍是阻碍其发展的最大技术瓶颈.石墨负极作为锂离子电池的重要组成部分,在电池热失控后,其燃烧反应产物对全电池的影响至关重要,为研究锂离子电池热失控前的荷电状态对热失控后燃烧产物的影响,我们调整荷电状态(State of Charge,SOC)分别到0％、50％、100％,洗去电极表面残余电解液
与普通的二次电池相比,锂离子电池具有更高的能量密度,因此在手机、笔记本电脑、数码相机等移动电器领域得到广泛的应用.然而,目前的锂离子电池技术并不能满足混合动力汽车、纯电动汽车的发展要求,需进一步提高其能量密度和功率密度.
自Wright课题组[1]发现聚氧乙烯-碱金属盐复合体系在室温下具有离子导电性以来,锂离子电池用聚合物固态电解质受到了学术界的广泛关注[2].研究普遍认为锂离子的迁移与聚合物链段的运动有关[3],锂离子的传输主要存在于无定形区[4].
太阳能电池产业发展趋势包括提高电池光电转换效率和实现晶体硅的薄片化.当前获得减反射绒面的湿法刻蚀工艺需要对晶体硅片进行双面刻蚀,从而增加了不必要的硅材厚度损失与碎片率[1].同时,晶体硅的薄片化增加了表面少子复合效应,因此对丝网印刷制铝背场的背表面钝化技术提出了更高的要求,而背表绒面化不利于背钝化的实现[2].
近年来,染料敏化太阳能电池(DSSCs)越来越受到人们的关注[1].其中,对电极是DSSCs的重要组成部分,本课题组通过简单的固态高温热解的方法,一步合成了具有高结晶度的石墨化碳/碳化三铁复合材料(GC/Fe3C).
