Abstract

Rechargeable lithium-ion batteries power consumer electronics and electric vehicles, making them an essential component of the modern economy. Although lithium-ion battery technology has improved continuously over the past decades, widespread adoption of electrified transportation requires charging in less than 15 min to be competitive with internal combustion engines. As a battery charges and discharges, lithium ions travel across the electrode-electrolyte interface. The rate at which lithium ions transfer is dictated by the structure and physical properties of electrolytes and lithium-storing electrodes. Yet, the exact chemical reaction mechanism underlying the insertion of lithium ions at the electrode-electrolyte interface remains elusive. On page 46 of this issue, Zhang et al. (1) report experimental evidence that shows that lithium-ion battery charge and discharge occur through a coupled ion-electron transfer mechanism. This could establish an experimental and theoretical platform to extract key parameters for optimizing charge transfer rates in lithium-ion batteries.
电池充电走向量子化
可充电锂离子电池为消费电子产品和电动汽车提供动力,使其成为现代经济的重要组成部分。尽管锂离子电池技术在过去几十年中不断改进,但电气化交通的广泛采用要求充电时间少于15分钟,才能与内燃机竞争。当电池充电和放电时,锂离子穿过电极-电解质界面。锂离子转移的速率取决于电解质和锂存储电极的结构和物理性质。然而,锂离子在电极-电解质界面插入的确切化学反应机制仍然难以捉摸。在这期的第46页,Zhang等人(1)报告了实验证据,表明锂离子电池的充放电是通过离子-电子耦合转移机制发生的。这可以为提取优化锂离子电池电荷转移速率的关键参数建立一个实验和理论平台。

期刊介绍: Science is a leading outlet for scientific news, commentary, and cutting-edge research. Through its print and online incarnations, Science reaches an estimated worldwide readership of more than one million. Science’s authorship is global too, and its articles consistently rank among the world's most cited research. Science serves as a forum for discussion of important issues related to the advancement of science by publishing material on which a consensus has been reached as well as including the presentation of minority or conflicting points of view. Accordingly, all articles published in Science—including editorials, news and comment, and book reviews—are signed and reflect the individual views of the authors and not official points of view adopted by AAAS or the institutions with which the authors are affiliated. Science seeks to publish those papers that are most influential in their fields or across fields and that will significantly advance scientific understanding. Selected papers should present novel and broadly important data, syntheses, or concepts. They should merit recognition by the wider scientific community and general public provided by publication in Science, beyond that provided by specialty journals. Science welcomes submissions from all fields of science and from any source. The editors are committed to the prompt evaluation and publication of submitted papers while upholding high standards that support reproducibility of published research. Science is published weekly; selected papers are published online ahead of print.
