Abstract

The urgent demand for stable electrode materials, especially for the anode, arises in the pursuit of high-energy Li-ion batteries. This research focuses on bismuth oxide (Bi₂O₃) and uncovers its performance through a straightforward, commercially viable synthesis route, along with the optimization of binders and electrolytes. By employing a sodium carboxymethyl cellulose binder and fluoroethylene carbonate additives, the Bi₂O₃ anode demonstrates significantly enhanced performance compared to prior studies. It attains an impressive initial capacity of approximately 750 mA h g⁻¹, exhibits excellent rate capability at 1000 mA g⁻¹ and maintains stable cycling performance over 6000 cycles.

通过简单合成提高 Bi2O3 的电化学性能，将其作为超长循环寿命锂离子电池的负极材料

在开发高能锂离子电池的过程中，对稳定的电极材料，尤其是阳极材料的需求十分迫切。本研究以氧化铋（Bi2O3）为重点，通过直接、商业上可行的合成路线以及粘合剂和电解质的优化，揭示了其性能。通过采用羧甲基纤维素钠粘合剂和氟碳酸乙烯添加剂，Bi2O3 阳极的性能较之前的研究有了显著提高。它达到了令人印象深刻的初始容量（约 750 mA h g-1），在 1000 mA g-1 时表现出卓越的速率能力，并在 6000 个循环周期内保持稳定的循环性能。

期刊介绍： Electrochemistry Communications is an open access journal providing fast dissemination of short communications, full communications and mini reviews covering the whole field of electrochemistry which merit urgent publication. Short communications are limited to a maximum of 20,000 characters (including spaces) while full communications and mini reviews are limited to 25,000 characters (including spaces). Supplementary information is permitted for full communications and mini reviews but not for short communications. We aim to be the fastest journal in electrochemistry for these types of papers.
