Abstract

The increasing demand for advanced battery redox chemistry, surpassing intercalation, conversion, and alloying processes, is pivotal in driving the rapid progress of next-generation rechargeable batteries. Herein, we discover a new ionic storage mechanism of combined intercalation and space-charging chemistry in the transition metal dichalcogenides (TMDs) of group IV and V elements (specifically Ti, Nb, and Ta). Taking NbS2 as an example, a new ternary intercalation compound Cu0.43DME0.12NbS2 is spontaneously formed through a Cu+-ether co-intercalation process with Cu current collectors in ether-based electrolytes. Subsequently, Na+ ions can reversibly (de)intercalate into Cu0.43DME0.12NbS2 with limited volume expansion, and Na+ can adsorb on the surface of in-situ electrochemical-induced Cu nanoparticles with fast kinetics and extra storage. Such synergistic processes enable a high specific capacity of 705 mAh g-1, surpassing its theoretical limit, a superior rate capability of 116 mAh g-1 at 75 A g-1, and an impressive cycle longevity over 1 year. Combined with Na3V2(PO4)3 (NVP), the full cell demonstrates an exceptional power density of 17453 W kg-1. The study paves the way for designing functional electrode materials for high-power and long-lifespan batteries.

期刊介绍: Energy & Environmental Science, a peer-reviewed scientific journal, publishes original research and review articles covering interdisciplinary topics in the (bio)chemical and (bio)physical sciences, as well as chemical engineering disciplines. Published monthly by the Royal Society of Chemistry (RSC), a not-for-profit publisher, Energy & Environmental Science is recognized as a leading journal. It boasts an impressive impact factor of 8.500 as of 2009, ranking 8th among 140 journals in the category "Chemistry, Multidisciplinary," second among 71 journals in "Energy & Fuels," second among 128 journals in "Engineering, Chemical," and first among 181 scientific journals in "Environmental Sciences." Energy & Environmental Science publishes various types of articles, including Research Papers (original scientific work), Review Articles, Perspectives, and Minireviews (feature review-type articles of broad interest), Communications (original scientific work of an urgent nature), Opinions (personal, often speculative viewpoints or hypotheses on current topics), and Analysis Articles (in-depth examination of energy-related issues).
