美利用3D打印机制造出沙粒大小微电池
美利用 3D打印机 制造 微电池
2013/6/20
据物理学家组织网6月18日报道，美国哈佛大学和伊利诺伊大学厄巴纳—尚佩恩分校研究人员合作，开发出一种3D打印的锂离子微电池，只有一粒沙子大小，而电化性能可媲美商用蓄电池。微电池可以为医疗、通讯等领域的微型设备，包括许多尚在实验室里、缺乏小电池的发明提供足够电力。相关论文在线发表于《先进材料》杂志上。
The self-assembly of artificial 3D nanostructures on a surface has been achieved for the first time, claims a team of researchers in the UK. Until now, such assembly was only possible in 2D and the sc...
