摘要(中) 近年來普魯士藍成為研究領域高度研究的話題,其中在應用在充放電電池之陰極材料擁有良好的成效,它具有穩定的三維結構框架,及具均勻的孔洞結構能容納多數鹼金屬陽離子,達到良好的電池充放電反應,有著低成本、壽命長且製作過程也環保的特質。
本研究以共沉積法製作Na-FeFe普魯士藍,分別以25°C、50°C、70°C以及85°C滴定溫度製作四種不同粒徑大小之樣品。利用X光繞射分析樣品晶格結構與了解化學組成成分,依不同的滴定溫度製作出粒徑12 nm、21 nm、37 nm以及54 nm之大小,於製作陰極極片添加銀奈米顆粒,將普魯士藍與銀奈米顆粒均勻混和塗布與烘乾,隨後壓定成電池,討論其電池充放電效率之影響。
將85°C滴定溫度54 nm 添加不同比例之銀奈米顆粒,比例分別為14%、25%以及35%之銀奈米顆粒,測試電池充放電循環效能分析。另外也討論利用不同充放電電流進行測試,探討不同電流對電池的效能穩定性與影響。
摘要(英) In recent years, Prussian blue has become a highly researched topic in the research field. Among them, it has good results in the application of cathode materials in charge and discharge batteries. It has a stable three-dimensional structural framework and a uniform pore structure that can accommodate most alkali metal cations. It has the characteristics of low cost, long life and environmentally friendly production process.
In this study, Na-FeFe Prussian blue was prepared by co-deposition method, and four samples with different particle sizes were prepared at 25°C, 50°C, 70°C and 85°C titration temperature respectively. Using X-ray diffraction to analyze the lattice structure of the sample and understand the chemical composition, the particle sizes of 12 nm, 21 nm, 37 nm and 54 nm were prepared according to different titration temperatures, and silver nanoparticles were added to the cathode electrode piece. Prussian blue and silver nanoparticles were uniformly mixed, coated and dried, and then pressed to form a battery, and the influence of the battery charge and discharge efficiency was discussed.
The 85°C titration temperature of 54 nm was added with different proportions of silver nanoparticles, the proportions of which were 14%, 25% and 35%, respectively, to test the battery charge-discharge cycle performance analysis. In addition, it also discusses the use of different charging and discharging currents for testing, and discusses the performance stability and impact of different currents on the battery.
