LITHIUM SECONDARY BATTERY AND METHOD FOR MANUFACTURING SAME

摘要

The present invention is a manufacturing method for a lithium secondary battery, wherein a negative electrode composite material layer, which is formed on a negative electrode for the battery, has a maximum point in each of (A) a pore diameter range of 0.3 - 4 µm and (B) a pore diameter range of 0 - less than 0.3µm in pore distribution measurements based on the mercury intrusion technique. The ratio (VA/VB) of a maximum point for pore volume (VA) for the range in A and a maximum point for pore volume (VB) for the range in B is 2.1 - 3.4.
