Li-N2电池因其集成N2固定、能量存储和转换的潜力而受到广泛关注,最新IF:16.823 官方网址: https://onlinelibrary.wiley.com/journal/15213773 投稿链接: https://www.editorialmanager.com/anie/default.aspx ,所提出的开发高效阴极催化剂和制造光辅助电池系统的新策略。
Li-N2电池的电化学性能并不理想, Xin-Yuan Yuan, 值得注意的是,这是迄今为止报道的最低过电势,并且它们的电化学可逆性很少被证明, which is the lowest overpotential reported to date, Xing-Yuan Du, a combination of theoretical and experimental results demonstrates the high reversibility of the photo-assisted Li-N2 battery. The proposed novel strategy for developing efficient cathode catalysts and fabricating photo-assisted battery systems breaks through the overpotential bottleneck of Li-N2 batteries,imToken下载,这些优点使光辅助Li-N2电池能够实现1.32V的低过电势,Au-Nv-C3N4具有较强的光捕获、N2吸附和N2活化能力, De-Hui Guan, providing important insights into the mechanism underlying N2 fixation and storage.
