Embodiment Construction

[0048] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

[0049] image 3 It is an exploded perspective view schematically showing a battery cell frame structure according to an embodiment of the present invention.

[0050] refer to image 3 , the battery unit frame structure includes a pouch battery unit 10 and a frame 100 for accommodating the pouch battery unit 10 .

[0051]The pouch battery unit 10 incorporates an electrode assembly (not shown) including an anode, a cathode, and a separation membrane disposed between the pouch case inside the pouch case. In addition, respective ends (taps) of the anode and the cathode are connected to a pair of electrode leads 11 and exposed on one side of the pouch cell 10 . The detailed structure of the pouch battery unit 10 is the same as or similar to known ones, and thus detailed description thereof will be omitted. The electrode lead 11 can be divided into an anode 11a ...

Abstract

The present invention discloses a cell unit frame stuctural body. According to an embodiment of the present invention, the frame stuctural body comprises: a bag-type cell unit, one side thereof is formed with a pair of electrode leads; a plurality of frames which are arranged on both sides of the bag and the battery cells and are combined with each other and accommodate the bag-type cell unit. The frame comprises: a first unit frame, the bag is disposed on one side of the battery cell; and a second unit frame having a first unit cell in the bag as a reference by 180-degree rotationally symmetrical shape and being combined with the first unit frame.

Description

technical field [0001] The present invention relates to a battery cell frame structure formed by combining a plurality of battery cell frames accommodating battery cells therein. Background technique [0002] With the active use of various electronic devices, the importance of chargeable and dischargeable secondary batteries as driving power sources is increasing. Lithium secondary batteries, in particular, are most widely used because they have a relatively high energy density per unit weight and can be rapidly charged compared to other secondary batteries. [0003] Generally, a secondary battery is manufactured by a cell module assembly (CMA, Cell Module Assembly) in which a plurality of battery cells are connected in series or in parallel. [0004] figure 1 It is a diagram schematically showing a conventional battery module assembly 10 . [0005] refer to figure 1 , the battery module assembly 10 includes: battery cells 11 connected in series or in parallel; a lower c...
