PURPOSE:To provide a negative electrode, which is good on an output characteristic and a low temperature characteristic, for non-aqueous secondary battery. CONSTITUTION:In a porous negative electrode mainly consisting of carbonaceous material grains, the carbonaceous material grain mainly consists of a graphitic grain whose spacing d002 of a carbon network face is less than 0.337nm. The porous negative electrode whose percentage of the volume occupied by the holes, whose porosity is 10% or more and less than 60% while its hole diameter ranges from 0.1mum to 10mum, to the whole porous volume is 80% or more is used. Therefore, a high capacity non-aqueous secondary battery, which is good on an output characteristic and a low temperature characteristic, can be obtained by employing this porous negative electrode. |
