Power lithium ion battery module without shell and frame

The invention relates to the technical field of new energy automobile power batteries, and particularly discloses a shell and frame-free power lithium ion battery module which comprises a first clamping plate and a second clamping plate, connecting devices are arranged on the periphery of the first clamping plate and the periphery of the second clamping plate, and a limiting device is arranged between the first clamping plate and the second clamping plate. The limiting device comprises an object bearing barrel, embedded tables are arranged on the left side and the rear portion of the object bearing barrel, and the embedded tables and the object bearing barrel are of an integrated structure. Caulking grooves are formed in the right side and the front side of the object bearing barrel, and the caulking tables are matched with the caulking grooves. According to the lithium ion battery module, the battery is protected through the detachable limiting device, so that a shell and a frame do not need to be designed d
