  循环碳酸盐基聚合物电解质增强4.45 V LiCoO2 / Li金属电池诱导的聚合物增强SEI层

  摘要：

  锂（Li）金属电池（LMB）由于能量密度高而正在复兴。然而，它们仍然遭受由固体电解质相间（SEI）层的连续裂化引起的不可控制的Li枝晶和粉化的问题。为了解决这些问题，在电化学调节过程中自发构建坚固的聚合物增强SEI层可以是一种简单而有效的解决方案。本文中，通过原位聚合方法提出了一种坚固的环状碳酸酯氨基甲酸酯甲基丙烯酸酯均聚物作为聚合物基质，其中环状碳酸酯单元可以在循环过程中参与构建稳定的聚合物集成SEI层。研究中的凝胶聚合物电解质（GPE）组装LiCoO 2/ Li金属电池具有出色的循环能力，在0.5 C（1 C = 180 mAh g -1）下200次循环后的容量保持率为92％，明显超过了使用液体电解质的电池。值得注意的是，在接近锂金属阳极的聚合物上，环状碳酸酯单元的阴离子开环聚合可实现机械增强的SEI层，从而与锂阳极具有出色的相容性。原位形成的聚合物增强SEI层为开发与Li金属阳极兼容

• Evaluation of a Potential Ionic Contribution to the Polymerization of Highly Reactive (Meth)acrylate Monomers

  Monovinyl methacrylic and acrylic monomers that exhibit enhanced photopolymerization reactivities were studied to discern a possible secondary polymerization mechanism that involves an anionic contribution to the polymerization. To test for this possible anionic contribution, a strong acid, methanesulfonic acid, was added in small quantities to each of the (meth)acrylic monomers, and the steady-state photopolymerization rate was monitored. Initial control studies with conventional free-radical polymerizing monomers showed that the polymerization rate of these conventional (meth)acrylic monomers are not affected by small amounts of acid. Acid studies of secondary functionalized (meth)acrylate monomers, which typically exhibit rapid polymerization kinetics, demonstrated that the polymerization rate is decreased in these monomers by the addition of the strong acid. More specifically, the acid addition had a greater inhibitory effect on the monomers with faster bulk polymerization rates. The acid addition had a much more profound effect on the polymerization rate of the acrylate monomers compared to analogous methaerylate monomers. More specifically, addition of 250 ppm of the strong acid to the phenyl carbamate acrylate monomer showed that both the steady-state and unsteady-state polymerization profiles were similar to that of a traditional free-radical acrylate monomer. All experiments indicate that an anionic contribution to the polymerization is probable and has a profound impact on the polymerization rate.

  these issues, developing spontaneously built robust polymer‐reinforced SEI layers during electrochemical conditioning can be a simple yet effective solution. Herein, a robust homopolymer of cyclic carbonate urethane methacrylate is presented as the polymer matrix through an in situ polymerization method, in which cyclic carbonate units can participate in building a stable polymer‐integrated SEI layer during
