LITHIUM SECONDARY BATTERY AND METHOD FOR MANUFACTURING SAME

摘要

A method is provided for manufacturing a lithium secondary battery, wherein a negative electrode composite material layer formed on a negative electrode in this battery has a maximum point, in accordance with measurement of the pore distribution based on a mercury intrusion technique, in the pore diameter range (A) of from at least 0.3 μm to not more than 4 μm and in the pore diameter range (B) of from at least 0 μm to less than 0.3 μm, and has a ratio (VA/VB) between the pore volume (VA) at the maximum point in the range A and the pore volume (VB) at the maximum point in the range B of from at least 2.1 to not more than 3.4.
