A new electrolyte solvent—1,1,3,3-tetramethylurea (TMU) is proposed for lithium–oxygen batteries (LOBs). Benefiting from its strong Li⁺-solvating ability and the absence of α-hydrogen atoms, a kinetically favorable one-electron Li₂O₂ oxidation pathway can occur in the charge process, and the hydrogen extraction side reactions can be effectively suppressed. Consequently, the TMU-based LOBs exhibit a low charge overpotential and a long cycle life.

使用具有动力学有利的单电子 Li2O2 氧化途径的尿素基电解质的高性能锂氧电池

一种新的电解质溶剂——1,1,3,3-四甲基脲（TMU）被提出用于锂氧电池（LOB）。得益于其强的Li ⁺溶剂化能力和不存在α-氢原子，在充电过程中可以发生动力学上有利的单电子Li ₂ O ₂氧化途径，并且可以有效抑制氢提取副反应。因此，基于 TMU 的 LOB 表现出低充电过电位和长循环寿命。
