Abstract

Rechargeable metal-based batteries with the highest theoretical energy densities stand as highly promising candidates for next-generation energy storage devices. However, despite substantial progress in cycling reversibility, their calendar life remains critically undermined by persistent metal corrosion. This mismatch highlights corrosion as a distinct electrochemical process governed by an electron transfer pathway that differs fundamentally from that of operational cycling, particularly under non-operational (rest) conditions. Although corrosion-related studies have emerged across various battery chemistries, they have largely remained fragmented without a cohesive, in-depth understanding. In this perspective, we highlight ongoing debates surrounding corrosion phenomena and their mechanistic understandings, with particular emphasis on their critical implications for the calendar life. Building upon this expanded discussion, we integrate insights from existing corrosion suppression strategies and propose a spectrum of promising design principles—spanning metal electrode fabrication, surface modification, and electrolyte engineering—with the aim of fostering further developments in this important area.

新一代可充电金属电池的腐蚀挑战
具有最高理论能量密度的可充电金属基电池是下一代储能设备的极有前途的候选者。然而,尽管在循环可逆性方面取得了实质性进展,但它们的日历寿命仍然受到持续金属腐蚀的严重破坏。这种不匹配强调了腐蚀是一种独特的电化学过程,由电子传递途径控制,与操作循环有着根本的不同,特别是在非操作(休息)条件下。尽管与腐蚀相关的研究已经出现在各种电池化学成分中,但它们在很大程度上仍然是零散的,没有一个连贯的、深入的理解。从这个角度来看,我们强调了围绕腐蚀现象及其机制理解的持续争论,特别强调了它们对日历寿命的关键影响。在此扩展讨论的基础上,我们整合了现有腐蚀抑制策略的见解,并提出了一系列有前途的设计原则-跨越金属电极制造,表面改性和电解质工程-旨在促进这一重要领域的进一步发展。
