The invention relates to the technical field of lithium ion batteries, in particular to an assembling frame of a lithium battery, a battery module and an assembling method of the battery module. The assembly frame of the lithium battery comprises a cover plate at the top and a plurality of spacers clamped below the cover plate, and bayonet positions of the cover plate are matched with buckle positions of the spacers; the battery module of the lithium battery comprises an acquisition wire harness, a single battery, a busbar, a terminal base, an end plate and a side plate. The cost is low, the universality is high, and production is easy; most parts are manufactured in a non-mold-opening mode, so that the mold opening cost is saved; the spacers between the batteries can play an insulating role and can also fix the wire harness and the cover plate, meanwhile, common complex plastic parts with the tops restraining the batteries are omitted, and the mold opening cost is saved; when single batteries of the same spe
