Abstract

Highlights

A systematic comparison of anode-free lithium, sodium, and potassium battery systems, emphasizing their distinct energy density, volume change, and interfacial instability.
A current-collector-centered analysis of anode-free alkali metal batteries, highlighting how current collectors govern alkali metal nucleation, growth, stripping, and interphase evolution under limited alkali metal inventory.
A practical framework for the development of anode-free alkali metal batteries, integrating performance metrics, current collector design parameters, and manufacturability constraints.

实用无阳极碱金属电池阳极集流器的设计。

在简化电池配置的同时，无阳极碱金属电池（AFAMBs）正在成为超越锂离子电池电池级能量密度限制的一种引人注目的策略。在这些系统中，工作阳极在裸电流集电极上原位形成，并在有限碱金属库存的循环过程中不断重塑。因此，阳极集流器不仅是一个被动的电子导体，而且是一个多功能的界面平台，控制碱金属的成核、生长、剥离和界面演化。这篇综述探讨了无阳极锂、钠和钾系统之间的根本区别，并强调了实用AFAMBs的关键性能指标。然后总结了目前针对这些化学物质开发的集热器工程策略。确定了影响集热器设计的基本参数，包括电子导电性、碱金属亲和力、集热器形态和相间稳定性。最后，提出了在实际操作条件下平衡电化学性能和可制造性的实用设计原则。本文旨在阐明集电极依赖碱金属的设计逻辑，为下一代无阳极电池的实际开发提供指导。

期刊介绍： Nano-Micro Letters is a peer-reviewed, international, interdisciplinary, and open-access journal published under the SpringerOpen brand. Nano-Micro Letters focuses on the science, experiments, engineering, technologies, and applications of nano- or microscale structures and systems in various fields such as physics, chemistry, biology, material science, and pharmacy.It also explores the expanding interfaces between these fields. Nano-Micro Letters particularly emphasizes the bottom-up approach in the length scale from nano to micro. This approach is crucial for achieving industrial applications in nanotechnology, as it involves the assembly, modification, and control of nanostructures on a microscale.
