The invention discloses a lithium ion battery, and an assembling method thereof, and belongs to the field of lithium battery. The assembling method is capable of solving a problem in the prior art that battery cost is increased because of electrical core swelling. The lithium ion battery comprises a support, and a battery casing used for accommodating the support; the support comprises an accommodating cavity and an upper cover; a plurality of sheet-shaped electrical cores are vertically arranged in the accommodating cavity, and are piled successively in the transverse direction; the side wallof the accommodating cavity is pressed against by a pressing belt, and the pressing direction is consist to that of the electrical core piling direction. The above structure is beneficial for realizing of rapid assembling, and reducing of manufacturing cost. The assembling method comprises following steps: 1, the electrical cores and a combination plate are arranged in the accommodating cavity; 2, the pressing belt is as
