在MXene表面构建人工SEI助力长寿命无枝晶锂金属负极
WebLithium (Li) metal is one of the most promising anode materials but suffers from inhomogeneous Li deposition, which is a limiting factor for the practical application of Li metal batteries. Some metals with high lithiophilicity are extremely recognized for achieving uniform Li deposition, but how these metals work is still unknown. Web事实上,锂 (Li) 主体、保护层和固态电解质 (SSE) 的先进设计被广泛用于高性能 LMB,以解决不稳定的固体电解质界面 (SEI) 和锂枝晶问题。 然而,大多数这些设计所表现出的亲锂性较差,无法调节初始锂成核,导致锂沉积不均匀,不可避免地导致枝晶生长。 近年来,通过提高亲锂性来调节锂的成核过电位的研究不断增多。 特别是亲锂材料的利用,可以有效 … Web13 sep. 2024 · Lithium metal batteries suffer from the dendrite growth upon electrochemical cycling.
