1.NiSi alloy powders were prepared by high energy ball-milling. The elemental powders of Si (―325 mesh, 99%;Aldrich) and Ni (―100 mesh, 99.8%; Aldrich) as well as hardened steel balls were put into the steel vial. 2.The alloy powders were characterised by X-ray diffraction on a Philips PW1730 diffractometers with a Cu Kα radiation and by scanning electron microscopy。 3. Lithium foil was used as counter and reference electrodes and Merck Selectipur LP32(1M LiPF6 in 2:1 DC/EC)was used as the electrolyte. 4.An Arbin battery testing system was used for galvanostatic cycling. All cells were cycled at 15mA/g active material and 20℃ unless otherwise noted. |

The elemental powders of Si (―325 mesh, 99%;Aldrich) and Ni (―100 mesh, 99.8%; Aldrich) as well as hardened steel balls were put into the steel vial. 通过高能球磨制备NiSi合金粉末。将Si（-325目，99％Aldrich）与Ni（-100目，99.8 ％Aldrich）基本粉体以及硬质刚球一同放入不锈钢容器中。 Aldrich这个专业词汇，我没见过，不知具体的意思。 [ Last edited by weichang on 2009-5-23 at 20:43 ] |
