LITHIUM SECONDARY CELL

WIPO Patent Application WO/2000/042669

A1

A lithium secondary cell comprising a positive electrode (10') capable of releasing and capturing lithium ions, a negative electrode (20') made of a material capable of being doped with lithium ions and being dedoped of lithium ions, metallic lithium, or a lithium alloy, and an electrolyte allowing migration of lithium ions, wherein at least either the positive electrode (10') or the negative electrode (20') is formed on a current collector (11') having an insulating resin layer (12') and a metal conductive layer (13') formed on the resin layer (12'), the thickness of the metal conductive layer (13') is 2.5 to 5 $g(m)m, and through holes (14') are preferably made through at least the metal conductive layer (13') in the direction of the thickness thereof.
