J. Cent. South Univ. Technol. (2008) 15: 484-487 DOI: 10.1007/s11771-008-0091-y Relationship between initial efficiency and structure parameters of carbon anode material for Li-ion battery SHEN...; Abstract: The initial efficiency is a very important criterion for carbon anode material of Li-ion battery. The relationship between initial efficiency......
of a nanocomposite W-Cu material under arc breakdown was investigated. The arc erosion rates of the material were determined, and the eroded surfaces and arc erosion mechanisms were studied by scanning electron microscopy. It is concluded that the nanocomposite W-Cu electrical contact material shows a characteristic of spreading arcs. The arc breakdown of a commercially used W-Cu alloy was limited in a few areas......
