锂离子电池高压电解液研究进展

, 2018
传统碳酸酯类电解液在高压(>4.3V,vs.Li/Li~+)下易发生氧化分解反应,导致锂离子电池不可逆容量增加、循环性能下降.为解决这一问题,需从理论和实验两方面对电解液溶剂、锂盐、添加剂及其基本组成等进行针对性设计.耐高压溶剂是提升电解液稳定性的关键因素之一,既经济又有效,添加高浓锂盐是近年来研究较多的可提升电解液电化学窗口和循环稳定性的新策略.本工作从耐高压溶剂、高压添加剂和高浓锂盐三方面综述了近几年锂离子电池高压电解液的研究进展.

提高非晶硅薄膜太阳能电池开路电压的方法

, 2010
本发明公开了一种提高非晶硅薄膜太阳能电池开路电压的方法，该方法包括:在不透明衬底上，采用等离子体辅助化学气相沉积技术依次生长N型层、本征层和P型层，其中，P型层又分为P层和P+层;在生长P层时，将P层的生长时间延长t秒，在P层生长完毕后，保持氢气流量、温度和辉光功率不变，采用氢等离子体刻蚀方法对P层刻蚀t秒，接着生长P+层;电池从反应室取出后，用磁控溅射生长ITO透明电极。利用本发明，处理过程简便易行，既能够有效提高非晶硅薄膜太阳能电池的开路电压，得到大面积高开压的非晶硅薄膜太阳能电池，同时又具有成本低，
