摘要
本研究介绍了利用喷涂技术制造包覆碳纤维(CF)的磷酸铁锂(LFP),作为结构电池的正极元件。通过这种方法成功涂覆的碳纤维证明了其作为高效电流收集器的实用性。利用这种方法获得的电极进行了电化学评估。在 C/7 条件下进行的长时间循环测试中,最大比放电容量达到 146 mAh g-1,100 次循环后容量保持率为 77%。在以 1.5C 的较快 C 速率进行的速率性能评估中,容量测量值为 123 mAh g-1,容量保持率为 96%。喷涂技术是结构电池电极生产中一项前景广阔的技术,展示了其在优化多功能储能系统性能方面的潜力。
LiFePO4-coated carbon fibers as positive electrodes in structural batteries: Insights from spray coating technique
This study presents the fabrication of LiFePO4 (LFP)-coated carbon fibers (CFs) as a positive electrode component for structural batteries, utilizing a spray coating technique. The successful coating of CFs through this method demonstrated their usefulness as efficient current collectors. The electrodes obtained using this method underwent electrochemical evaluations. Throughout the extended cycling tests at C/7, the maximum specific discharge capacity reached 146 mAh/g, maintaining a 77% capacity retention after 100 cycles. In rate performance assessments at the faster C-rate of 1.5C, the capacity measured 123 mAh/g, with a retention of 96%. The application of spray coating emerges as a promising technique for electrode production in structural batteries, showcasing its potential for optimizing performance in multifunctional energy storage systems.
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.
