摘要
The present disclosure provides a lithium-ion battery and a deformable safety valve as an overcharge protection device thereof. The deformable safety valve as the overcharge protection device of the lithium-ion battery comprises a short-circuit conductive plate and a deformable plate made from aluminum, a facing surface of the deformable plate being coated with a metal layer to reduce contact resistance between the deformable plate and the short-circuit conductive plate. The lithium-ion battery comprises a first electrode post; a cap plate electrically connected to the first electrode post; an electrolyte-injection hole provided in the cap plate; a vent provided in the cap plate; a deformable safety valve provided to the cap plate; and a second electrode post assembled to the cap plate in an insulating manner; wherein the deformable safety valve is the above deformable safety valve as the overcharge protection device of the lithium-ion battery.
