Claim:
1. An electrode plate of a lithium-ion battery, comprising: a collector; a film containing an active material formed on the collector, and the film and the collector forming an elementary electrode plate; and a lithium metal sheet having uniformly-distributed through holes and covering the film of the elementary electrode plate, wherein: each through hole has a predefined dimension such that the lithium metal sheet has a remaining area corresponding to a resulting capacity equal to or less than a predefined lithium-supplemental capacity of an anode of a lithium-ion battery made from the electrode plate; the lithium metal sheet increases a gap between the anode and a cathode of the lithium-ion battery; and the uniformly-distributed through holes in the lithium metal sheet improve an entry velocity of electrolyte flowing through the lithium metal sheet when the electrolyte is injected into the lithium-ion battery.
