Abstract: A lithium battery cell includes an upper cover module, a first battery electrode group, a second battery electrode group, and a plurality of first electrode connection straps. The first electrode connection straps are stacked together and have the same width and length. A first end of the first electrode connection straps is welded to a first tab, a second end of the first electrode connection straps is welded to a second tab, and a middle part of the first electrode connection straps is welded to a first electrode terminal. An even number of first bending parts are formed between the middle part and the first end, and an even number of second bending parts are formed between the middle part and the second end, and the first bending parts and the second bending parts are symmetrical to each other. Furthermore, a lithium battery cell manufacturing method is also disclosed therein.

Abstract: A multifunctional probe includes a hand-held housing, a signal detector and an array probe. The signal detector is flexibly disposed on the hand-held housing or at its first end. The array probe is disposed at one end (e.g., second end) of the hand-held housing and electrically coupled to the signal detector. The first contact time of the signal detector in contact with the living body may at least partially overlap with the second contact time of the array probe in contact with the living body. The signal detector and the array probe generate the first electronic signal. The multifunctional probe includes a flexibly-connected signal detector and an array probe, which can contact and/or detect the living body at the same time. Thus, the detection efficiency and accuracy are effectively increased. A detection method applied to the multifunctional probe is also provided.
