Abstract
Disclosed are a plate assembly for a battery, a core and a lithium ion battery. The plate assembly comprises a plate, a conductive terminal and a membrane bag, the plate is encapsulated in the membrane bag, an encapsulation line is formed when the membrane bag is encapsulated, and the conductive terminal is disposed at one end of the plate and protruded out of the membrane bag, wherein the encapsulation line has at least two loops around the periphery of the plate. The core comprises the plate assembly of the present invention. The lithium ion battery comprises the core of the present invention. Since the membrane bag included in the plate assembly of the present invention is encapsulated by at least two loops of encapsulation line around the periphery of the plate, the membrane bag can be encapsulated tightly, which can prevent effectively the membrane bag from being cracked, and prevent the short circuit from being occurred due to the contact of the positive and negative plates, and thereby effectively improves the mechanical impact resistance of the battery.
