Spheroidization: The Impact of Precursor Morphology on Solid‐State Lithiation Process for High‐Quality Ultrahigh‐Nickel Oxide Cathodes

Angewandte Chemie International Edition, Год журнала: 2024, Номер 63(34)

Опубликована: Июнь 7, 2024

Abstract Layered oxides with ultrahigh nickel content are considered promising high energy cathode materials. However, their cycle stability is constrained by a series of heterogeneous structural transformations during the complex solid‐state lithiation process. By in‐depth investigation into process LiNi 0.92 Co 0.04 Mn O 2 , it found that protruded parts on surface precursor particles tend to be surrounded locally excessive LiOH, which promotes formation rigid and dense shell early stage The will hinder diffusion lithium topotactic within particles, culminating in spatially intermediates can impair electrochemical properties material. spheroidization enhance uniformity evolution solid‐phase lithiation. Ultrahigh cathodes derived from spherical precursors demonstrate initial discharge specific capacity (234.2 mAh g −1 range 2.7–4.3 V) retention (89.3 % after 200 cycles), significantly superior non‐spherical samples. This study not only sheds light intricate relationship between shape transformation but also introduces novel strategy for enhancing performance through spheroidization.

Abstract In past few decades, the rapid advancement of lithium battery technology has revolutionized our lives by powering portable electronic devices and vehicles. However, increasing risk thermal runaway (TR) poses significant challenges to their wider application, particularly regarding detrimental effects on electric vehicles large‐scale energy storage. The separator, serving as a barrier between cathode anode, is critical in preventing active materials generate Joule heat, thereby playing vital role ensuring safety. As understanding TR mechanism deepens, it evident that numerous exothermic reactions substances are closely linked separator. Consequently, functional design development runaway‐blocking separators (TR‐blocking separators) regarded key strategies for mitigating TR. intricate relationships these remain poorly understood, making challenging gain progress targeted separators. This review presents an in‐depth analysis regulating internal side batteries minimize heat release during TR, summarize advancements TR‐blocking enhancing safety at different stages. Furthermore, insights into presented based previous studies various unfavorable reactions. Additionally, future directions suggested
