Title: SECONDARY BATTERY
Abstract:
An embodiment of the present invention provides a secondary battery including an electrode plate (for example, a negative plate), a one-side coated portion of which has a resistance higher than that of a both-side coated portion thereof, so as to minimize a difference of current amount between the one-side coated portion and the both-side coated portion.
