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.

Lithium battery cell and manufacturing method thereof

An underwater ultrasonic device includes a curvilinear ultrasonic transducer and a plurality of straight linear ultrasonic transducers. The straight linear ultrasonic transducers are disposed with respect to the curvilinear ultrasonic transducer. A first angle is included between the straight linear ultrasonic transducers. One of the curvilinear ultrasonic transducer and the straight linear ultrasonic transducer is configured to transmit a plurality of ultrasonic signals. Another one of the curvilinear ultrasonic transducer and the straight linear ultrasonic transducer is configured to receive a plurality of reflected signals of the ultrasonic signals.
