‘Anode-free’ Li metal batteries offer the highest possible energy density but face low Li coulombic efficiency when operated in carbonate electrolytes. Here we report a performance improvement of anode-free Li metal batteries using p-block tin octoate additive in the carbonate electrolyte. We show that the preferential adsorption of the octoate moiety on the Cu substrate induces the construction of a carbonate-less protective layer, which inhibits the side reactions and contributes to the uniform Li plating. In the mean time, the reduction of Sn2+ at the initial charging process builds a stable lithophilic layer of Cu6Sn5 alloy and Sn, improving the affinity between the Li and the Cu substrate. Notably, anode-free Li metal pouch cells with tin octoate additive demonstrate good cycling stability with a high coulombic efficiency of ~99.1%. Furthermore, this in situ p-block layer plating strategy is also demonstrated with other types of p-block metal octoate, as well as a Na metal battery system, demonstrating the high level of universality.
无阳极 "金属锂电池具有最高的能量密度，但在碳酸盐电解质中运行时，锂的库仑效率较低。在此，我们报告了在碳酸盐电解质中使用辛酸锡添加剂提高无阳极金属锂电池性能的方法。我们的研究表明，辛酸锡分子在铜基板上的优先吸附作用诱导构建了无碳酸盐保护层，从而抑制了副反应并促进了锂的均匀电镀。与此同时，初始充电过程中 Sn2+ 的还原作用在 Cu6Sn5 合金和 Sn 之间形成了稳定的嗜石层，从而提高了锂与 Cu 基底之间的亲和力。值得注意的是，使用辛酸锡添加剂的无阳极锂金属袋电池表现出良好的循环稳定性，库仑效率高达约 99.1%。此外，这种原位 p 块层电镀策略还在其他类型的 p 块八酸盐金属以及 Na 金属电池系统中得到了验证，证明了其高度的通用性。

The question of whether all materials can be put into glass form was raised half a century ago but has remained unanswered. Using picosecond pulsed laser ablation, the vitrification of gold — which has been notoriously difficult — and several other monatomic metals is demonstrated, indicating that vitrification is an intrinsic property of matter.

Nonlinear physics is one of the most important research fields in modern physics and materials science. It offers an unprecedented paradigm for exploring many fascinating physical phenomena and realizing diverse cutting-edge applications inconceivable in the framework of linear processes. Here we review the recent theoretical and experimental progress concerning the nonlinear physics of synthetic quantum moiré superlattices. We focus on the emerging nonlinear electronic, optical and optoelectronic properties of moiré superlattices, including but not limited to the nonlinear anomalous Hall effect, dynamically twistable harmonic generation, nonlinear optical chirality, ultralow-power-threshold optical solitons and spontaneous photogalvanic effect. We also present our perspectives on the future opportunities and challenges in this rapidly progressing field, and highlight the implications for advances in both fundamental physics and technological innovations. This Review introduces emerging nonlinear electronic, optical and optoelectronic properties of moiré superlattices and discusses opportunities and challenges in this rapidly progressing field, as well as implications for fundamental physics and technological innovations.

Recent discoveries of Mott insulating and unconventional superconducting states in twisted bilayer graphene with moiré superlattices have not only reshaped the landscape of ‘twistronics’ but also sparked the rapidly growing fields of moiré photonic and phononic structures. These innovative moiré structures have opened new routes of exploration for classical wave physics, leading to intriguing phenomena and robust control of electromagnetic and mechanical waves. Drawing inspiration from the success of twisted bilayer graphene, this Perspective describes an overarching framework of the emerging moiré photonic and phononic structures that promise novel classical wave devices. We begin with the fundamentals of moiré superlattices, before highlighting recent studies that exploit twist angle and interlayer coupling as new ingredients with which to engineer and tailor the band structures and effective material properties of photonic and phononic structures. Finally, we discuss the future directions and prospects of this emerging area in materials science and wave physics. Platforms that exhibit moiré patterns have the potential to tailor band structures and control electromagnetic and mechanical waves. This Perspective discusses the current state of the art, challenges and outlook within the realm of classical wave physics.
