Abstract
When the composite particle containing Si or Sn is used for the negative electrode, the ratio of the median diameter 'Dc' of the conductive material to the median diameter 'Da' of the negative electrode material (Dc/Da) is made from 0.02 to 0.5 in order to improve reduction in electron conductivity, which is attributed to fine division of the particles due to repeated charge/discharge.
